Essay on Air Pollution

Environmental changes are caused by the natural or artificial content of harmful pollutants and can cause instability, disturbance, or adverse effects on the ecosystem. Earth and its environment pose a more serious threat due to the increasing pollution of air, water, and soil. Environmental damage is caused by improper resource management or careless human activities. Therefore, any activity that violates the original nature of the environment and leads to degradation is called pollution. We need to understand the origin of these pollutants and find ways to control pollution. This can also be done by raising awareness of the effects of pollutants.

Air pollution is any physical, chemical, or biological change in the air. A certain percentage of the gas is present in the atmosphere. Increasing or decreasing the composition of these gasses is detrimental to survival. This imbalance in gas composition causes an increase in global temperature which is called global warming.

Introduction to air pollution 

The Earth and its environment are facing a serious threat by the increasing pollution of the air, water, and soil—the vital life support systems of the Earth. The damage to the environment is caused by improper management of resources or by careless human activity. Hence any activity that violates the original character of nature and leads to its degradation is called pollution. We need to understand the sources of these pollutants and find ways to control pollution. This can be also done by making people aware of the effects of pollutants. 

Air with 78% Nitrogen, 21% Oxygen, and 1% of all other gasses support life on Earth. Various processes take place to sustain the regular percentage of gasses and their composition in general. 

Atmospheric pollution can have natural sources, for example, volcanic eruptions. The gaseous by-products of man-made processes such as energy production, waste incineration, transport, deforestation and agriculture, are the major air pollutants.

Although air is made up of mostly Oxygen and Nitrogen, mankind, through pollution, has increased the levels of many trace gasses, and in some cases, released completely new gasses to the atmosphere. 

Air pollution can result in poor air quality, both in cities and in the countryside. Some air pollutants make people sick, causing breathing problems and increasing the likelihood of cancer. 

Some air pollutants are harmful to plants, animals, and the ecosystems in which they live. Statues, monuments, and buildings are being corroded by the air pollutants in the form of acid rain. It also damages crops and forests, and makes lakes and streams unsuitable for fish and other plant and animal life. 

Air pollution created by man-made resources is also changing the Earth’s atmosphere. It is causing the depletion of the ozone layer and letting in more harmful radiation from the Sun. The greenhouse gasses released into the atmosphere prevents heat from escaping back into space and leads to a rise in global average temperatures. Global warming affects the average sea-level and increases the spread of tropical diseases.

Air pollution occurs when large amounts of gas and tiny particles are released into the air and the ecological balance is disturbed. Each year millions of tons of gasses and particulate matter are emitted into the air. 

Primary air pollutants are pollutants, which are directly released into the air. They are called SPM, i.e., Suspended Particulate Matter. For example, smoke, dust, ash, sulfur oxide, nitrogen oxide, and radioactive compounds, etc.

Secondary Pollutants are pollutants, which are formed due to chemical interactions between the atmospheric components and primary pollutants. For example, Smog (i.e. Smoke and fog), ozone, etc.

Major gaseous air pollutants include Carbon Dioxide, Hydrogen Sulfide, Sulfur Dioxide and Nitrogen Oxide, etc.

Natural sources are volcanic eruptions, forest fires, dust storms, etc. 

Man-made sources include gasses released from the automobiles, industries, burning of garbage and bricks kilns, etc.

Effects of Air Pollution on Human Health

Air pollution has adverse effects on human health. 

Breathing polluted air puts you at higher risk of asthma.

When exposed to ground ozone for 6 to 7 hours, people suffer from respiratory inflammation.

Damages the immune system, endocrine, and reproductive systems.

A high level of air pollution has been associated with higher incidents of heart problems.

The toxic chemicals released into the air are affecting the flora and fauna immensely.

Preventive Measures to Reduce Air Pollution

We can prevent pollution by utilizing raw materials, water energy, and other resources more efficiently. When less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process, human health can be protected and economic wellbeing can be strengthened. 

There are several measures that can be adopted by people to reduce pollution and to save the environment.

Carpooling.

Promotion of public transport.

No smoking zone.

Restricted use of fossil fuels.

Saving energy.

Encouraging organic farming.

The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gasses, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.

FAQs on Air Pollution Essay

1. State the Causes of Air Pollution ?

The following are the causes of air pollution.

Vehicular pollution consisting of Carbon Monoxide causes pollution.

Emission of Nitrogen oxide by a large number of supersonic transport airplanes causes deterioration of the Ozone layer and also causes serious damage to the flora and fauna.

The release of Chlorofluorocarbons into the Stratosphere causes depletion of Ozone, which is a serious concern to animals, microscopic, and aquatic organisms.

Burning garbage causes smoke, which pollutes the atmosphere. This smoke contains harmful gases such as Carbon dioxide and Nitrogen oxides.

In India, brick kilns are used for many purposes and coal is used to burn the bricks. They give out huge quantities of Carbon dioxide and particulate matter such as smoke, dust that are very harmful to people working there and the areas surrounding it. 

Many cleansing agents release poisonous gases such as Ammonia and Chlorine into the atmosphere. 

Radioactive elements emit harmful rays into the air.

Decomposed animals and plants emit Methane and Ammonia gas into the air.

2. What Does Global Warming Mean?

Global warming is the gradual rising average temperature of the Earth's atmosphere due to the concentration of methane in certain toxic gasses such as carbon dioxide. This has a major impact on the world climate. The world is warming. The land and the sea are now warmer than they were at the beginning and temperatures are still rising. This rise in temperature is, in short, global warming. This temperature rise is man-made. The burning of fossil fuels releases greenhouse gasses into the atmosphere which capture solar heat and raise surface and air temperatures.

3. Name the Alternative Modes of Transport. In What Way Does it Help to Reduce Air Pollution?

Public transport could be an alternative mode of transport. Public transport like trains, buses and trams, can relieve traffic congestion and reduce air pollution from road transport. The use of public transport must be encouraged in order to develop a sustainable transport policy.

4. Mention other means of transportation! How can I help reduce air pollution?

Public transportation can be another mode of transportation. Public transport such as trains, buses and trams can reduce traffic congestion and reduce air pollution from road transport. The use of public transport and to develop sustainable transport policies should be encouraged. While one passenger vehicle has the convenience factor, other modes of transportation reduce travel costs, spend less time, reduce stress, improve health, and reduce energy consumption and parking. Other trips for work include walking/cycling, public transport, hybrid travel and transport.

5. What are the effects of pollution?

Excessive air pollution can increase the risk of heart attack, wheezing, coughing and difficulty breathing, as well as irritation of the eyes, nose and throat. Air pollution can also cause heart problems, asthma, and other lung problems. Due to the emission of greenhouse gases, the composition of the air in the air is disturbed. This causes an increase in global temperature. The damaging ozone layer due to air pollution does not prevent harmful ultraviolet rays from the sun, which cause skin and eye problems in individuals. Air pollution has caused a number of respiratory and heart diseases among people. The incidence of lung cancer has increased in recent decades. Children living in contaminated areas are more likely to develop pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution. When burning fossil fuels, harmful gases such as nitrogen oxides and sulfur oxides are released into the air. Water droplets combine with these pollutants and become acidic and fall as acid rain, which harms human, animal and plant life.

6. What is the solution to air pollution?

Production of renewable fuels and clean energy. The basic solution to air pollution is to get away from fossil fuels and replace them with other energies such as solar, wind and geothermal. The government limits the amount of fossil fuel that can be used and how much carbon dioxide and other pollutants it can emit. While the government is trying to save our environment from this harmful gas, it is not enough. We as a society need to keep the environment clean by controlling air pollution.

ENCYCLOPEDIC ENTRY

Air pollution.

Air pollution consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. It also damages buildings.

Biology, Ecology, Earth Science, Geography

Air pollution consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. It also damages buildings. Pollutants in the air take many forms. They can be gases , solid particles, or liquid droplets. Sources of Air Pollution Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans . Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources . Some types of air pollution, such as smoke from wildfires or ash from volcanoes , occur naturally. These are called natural sources . Air pollution is most common in large cities where emissions from many different sources are concentrated . Sometimes, mountains or tall buildings prevent air pollution from spreading out. This air pollution often appears as a cloud making the air murky. It is called smog . The word "smog" comes from combining the words "smoke" and " fog ." Large cities in poor and developing nations tend to have more air pollution than cities in developed nations. According to the World Health Organization (WHO) , some of the worlds most polluted cities are Karachi, Pakistan; New Delhi, India; Beijing, China; Lima, Peru; and Cairo, Egypt. However, many developed nations also have air pollution problems. Los Angeles, California, is nicknamed Smog City. Indoor Air Pollution Air pollution is usually thought of as smoke from large factories or exhaust from vehicles. But there are many types of indoor air pollution as well. Heating a house by burning substances such as kerosene , wood, and coal can contaminate the air inside the house. Ash and smoke make breathing difficult, and they can stick to walls, food, and clothing. Naturally-occurring radon gas, a cancer -causing material, can also build up in homes. Radon is released through the surface of the Earth. Inexpensive systems installed by professionals can reduce radon levels. Some construction materials, including insulation , are also dangerous to people's health. In addition, ventilation , or air movement, in homes and rooms can lead to the spread of toxic mold . A single colony of mold may exist in a damp, cool place in a house, such as between walls. The mold's spores enter the air and spread throughout the house. People can become sick from breathing in the spores. Effects On Humans People experience a wide range of health effects from being exposed to air pollution. Effects can be broken down into short-term effects and long-term effects . Short-term effects, which are temporary , include illnesses such as pneumonia or bronchitis . They also include discomfort such as irritation to the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea . Bad smells made by factories, garbage , or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant . Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death. Long-term health effects from air pollution include heart disease , lung cancer, and respiratory diseases such as emphysema . Air pollution can also cause long-term damage to people's nerves , brain, kidneys , liver , and other organs. Some scientists suspect air pollutants cause birth defects . Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution. People react differently to different types of air pollution. Young children and older adults, whose immune systems tend to be weaker, are often more sensitive to pollution. Conditions such as asthma , heart disease, and lung disease can be made worse by exposure to air pollution. The length of exposure and amount and type of pollutants are also factors. Effects On The Environment Like people, animals, and plants, entire ecosystems can suffer effects from air pollution. Haze , like smog, is a visible type of air pollution that obscures shapes and colors. Hazy air pollution can even muffle sounds. Air pollution particles eventually fall back to Earth. Air pollution can directly contaminate the surface of bodies of water and soil . This can kill crops or reduce their yield . It can kill young trees and other plants. Sulfur dioxide and nitrogen oxide particles in the air, can create acid rain when they mix with water and oxygen in the atmosphere. These air pollutants come mostly from coal-fired power plants and motor vehicles . When acid rain falls to Earth, it damages plants by changing soil composition ; degrades water quality in rivers, lakes and streams; damages crops; and can cause buildings and monuments to decay . Like humans, animals can suffer health effects from exposure to air pollution. Birth defects, diseases, and lower reproductive rates have all been attributed to air pollution. Global Warming Global warming is an environmental phenomenon caused by natural and anthropogenic air pollution. It refers to rising air and ocean temperatures around the world. This temperature rise is at least partially caused by an increase in the amount of greenhouse gases in the atmosphere. Greenhouse gases trap heat energy in the Earths atmosphere. (Usually, more of Earths heat escapes into space.) Carbon dioxide is a greenhouse gas that has had the biggest effect on global warming. Carbon dioxide is emitted into the atmosphere by burning fossil fuels (coal, gasoline , and natural gas ). Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane , nitrous oxide , and fluorinated gases. Methane is a major emission from coal plants and agricultural processes. Nitrous oxide is a common emission from industrial factories, agriculture, and the burning of fossil fuels in cars. Fluorinated gases, such as hydrofluorocarbons , are emitted by industry. Fluorinated gases are often used instead of gases such as chlorofluorocarbons (CFCs). CFCs have been outlawed in many places because they deplete the ozone layer . Worldwide, many countries have taken steps to reduce or limit greenhouse gas emissions to combat global warming. The Kyoto Protocol , first adopted in Kyoto, Japan, in 1997, is an agreement between 183 countries that they will work to reduce their carbon dioxide emissions. The United States has not signed that treaty . Regulation In addition to the international Kyoto Protocol, most developed nations have adopted laws to regulate emissions and reduce air pollution. In the United States, debate is under way about a system called cap and trade to limit emissions. This system would cap, or place a limit, on the amount of pollution a company is allowed. Companies that exceeded their cap would have to pay. Companies that polluted less than their cap could trade or sell their remaining pollution allowance to other companies. Cap and trade would essentially pay companies to limit pollution. In 2006 the World Health Organization issued new Air Quality Guidelines. The WHOs guidelines are tougher than most individual countries existing guidelines. The WHO guidelines aim to reduce air pollution-related deaths by 15 percent a year. Reduction Anybody can take steps to reduce air pollution. Millions of people every day make simple changes in their lives to do this. Taking public transportation instead of driving a car, or riding a bike instead of traveling in carbon dioxide-emitting vehicles are a couple of ways to reduce air pollution. Avoiding aerosol cans, recycling yard trimmings instead of burning them, and not smoking cigarettes are others.

Downwinders The United States conducted tests of nuclear weapons at the Nevada Test Site in southern Nevada in the 1950s. These tests sent invisible radioactive particles into the atmosphere. These air pollution particles traveled with wind currents, eventually falling to Earth, sometimes hundreds of miles away in states including Idaho, Utah, Arizona, and Washington. These areas were considered to be "downwind" from the Nevada Test Site. Decades later, people living in those downwind areascalled "downwinders"began developing cancer at above-normal rates. In 1990, the U.S. government passed the Radiation Exposure Compensation Act. This law entitles some downwinders to payments of $50,000.

Greenhouse Gases There are five major greenhouse gases in Earth's atmosphere.

• water vapor
• carbon dioxide
• nitrous oxide

London Smog What has come to be known as the London Smog of 1952, or the Great Smog of 1952, was a four-day incident that sickened 100,000 people and caused as many as 12,000 deaths. Very cold weather in December 1952 led residents of London, England, to burn more coal to keep warm. Smoke and other pollutants became trapped by a thick fog that settled over the city. The polluted fog became so thick that people could only see a few meters in front of them.

What is air pollution?

What causes air pollution, effects of air pollution, air pollution in the united states, air pollution and environmental justice, controlling air pollution, how to help reduce air pollution, how to protect your health.

Air pollution  refers to the release of pollutants into the air—pollutants that are detrimental to human health and the planet as a whole. According to the  World Health Organization (WHO) , each year, indoor and outdoor air pollution is responsible for nearly seven million deaths around the globe. Ninety-nine percent of human beings currently breathe air that exceeds the WHO’s guideline limits for pollutants, with those living in low- and middle-income countries suffering the most. In the United States, the  Clean Air Act , established in 1970, authorizes the U.S. Environmental Protection Agency (EPA) to safeguard public health by regulating the emissions of these harmful air pollutants.

“Most air pollution comes from energy use and production,” says  John Walke , director of the Clean Air team at NRDC. Driving a car on gasoline, heating a home with oil, running a power plant on  fracked gas : In each case, a fossil fuel is burned and harmful chemicals and gases are released into the air.

“We’ve made progress over the last 50 years in improving air quality in the United States, thanks to the Clean Air Act. But climate change will make it harder in the future to meet pollution standards, which are designed to  protect health ,” says Walke.

Air pollution is now the world’s fourth-largest risk factor for early death. According to the 2020  State of Global Air  report —which summarizes the latest scientific understanding of air pollution around the world—4.5 million deaths were linked to outdoor air pollution exposures in 2019, and another 2.2 million deaths were caused by indoor air pollution. The world’s most populous countries, China and India, continue to bear the highest burdens of disease.

“Despite improvements in reducing global average mortality rates from air pollution, this report also serves as a sobering reminder that the climate crisis threatens to worsen air pollution problems significantly,” explains  Vijay Limaye , senior scientist in NRDC’s Science Office. Smog, for instance, is intensified by increased heat, forming when the weather is warmer and there’s more ultraviolet radiation. In addition, climate change increases the production of allergenic air pollutants, including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season). “Climate change–fueled droughts and dry conditions are also setting the stage for dangerous wildfires,” adds Limaye. “ Wildfire smoke can linger for days and pollute the air with particulate matter hundreds of miles downwind.”

The effects of air pollution on the human body vary, depending on the type of pollutant, the length and level of exposure, and other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.

Smog and soot

These are the two most prevalent types of air pollution. Smog (sometimes referred to as ground-level ozone) occurs when emissions from combusting fossil fuels react with sunlight. Soot—a type of  particulate matter —is made up of tiny particles of chemicals, soil, smoke, dust, or allergens that are carried in the air. The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines, generally anything that combusts fossil fuels such as coal, gasoline, or natural gas,” Walke says.

Smog can irritate the eyes and throat and also damage the lungs, especially those of children, senior citizens, and people who work or exercise outdoors. It’s even worse for people who have asthma or allergies; these extra pollutants can intensify their symptoms and trigger asthma attacks. The tiniest airborne particles in soot are especially dangerous because they can penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death. In  2020, a report from Harvard’s T.H. Chan School of Public Health showed that COVID-19 mortality rates were higher in areas with more particulate matter pollution than in areas with even slightly less, showing a correlation between the virus’s deadliness and long-term exposure to air pollution. 

These findings also illuminate an important  environmental justice issue . Because highways and polluting facilities have historically been sited in or next to low-income neighborhoods and communities of color, the negative effects of this pollution have been  disproportionately experienced by the people who live in these communities.

Hazardous air pollutants

A number of air pollutants pose severe health risks and can sometimes be fatal, even in small amounts. Almost 200 of them are regulated by law; some of the most common are mercury,  lead , dioxins, and benzene. “These are also most often emitted during gas or coal combustion, incineration, or—in the case of benzene—found in gasoline,” Walke says. Benzene, classified as a carcinogen by the EPA, can cause eye, skin, and lung irritation in the short term and blood disorders in the long term. Dioxins, more typically found in food but also present in small amounts in the air, is another carcinogen that can affect the liver in the short term and harm the immune, nervous, and endocrine systems, as well as reproductive functions.  Mercury  attacks the central nervous system. In large amounts, lead can damage children’s brains and kidneys, and even minimal exposure can affect children’s IQ and ability to learn.

Another category of toxic compounds, polycyclic aromatic hydrocarbons (PAHs), are by-products of traffic exhaust and wildfire smoke. In large amounts, they have been linked to eye and lung irritation, blood and liver issues, and even cancer.  In one study , the children of mothers exposed to PAHs during pregnancy showed slower brain-processing speeds and more pronounced symptoms of ADHD.

Greenhouse gases

While these climate pollutants don’t have the direct or immediate impacts on the human body associated with other air pollutants, like smog or hazardous chemicals, they are still harmful to our health. By trapping the earth’s heat in the atmosphere, greenhouse gases lead to warmer temperatures, which in turn lead to the hallmarks of climate change: rising sea levels, more extreme weather, heat-related deaths, and the increased transmission of infectious diseases. In 2021, carbon dioxide accounted for roughly 79 percent of the country’s total greenhouse gas emissions, and methane made up more than 11 percent. “Carbon dioxide comes from combusting fossil fuels, and methane comes from natural and industrial sources, including large amounts that are released during oil and gas drilling,” Walke says. “We emit far larger amounts of carbon dioxide, but methane is significantly more potent, so it’s also very destructive.” 

Another class of greenhouse gases,  hydrofluorocarbons (HFCs) , are thousands of times more powerful than carbon dioxide in their ability to trap heat. In October 2016, more than 140 countries signed the Kigali Agreement to reduce the use of these chemicals—which are found in air conditioners and refrigerators—and develop greener alternatives over time. (The United States officially signed onto the  Kigali Agreement in 2022.)

Pollen and mold

Mold and allergens from trees, weeds, and grass are also carried in the air, are exacerbated by climate change, and can be hazardous to health. Though they aren’t regulated, they can be considered a form of air pollution. “When homes, schools, or businesses get water damage, mold can grow and produce allergenic airborne pollutants,” says Kim Knowlton, professor of environmental health sciences at Columbia University and a former NRDC scientist. “ Mold exposure can precipitate asthma attacks  or an allergic response, and some molds can even produce toxins that would be dangerous for anyone to inhale.”

Pollen allergies are worsening  because of climate change . “Lab and field studies are showing that pollen-producing plants—especially ragweed—grow larger and produce more pollen when you increase the amount of carbon dioxide that they grow in,” Knowlton says. “Climate change also extends the pollen production season, and some studies are beginning to suggest that ragweed pollen itself might be becoming a more potent allergen.” If so, more people will suffer runny noses, fevers, itchy eyes, and other symptoms. “And for people with allergies and asthma, pollen peaks can precipitate asthma attacks, which are far more serious and can be life-threatening.”

More than one in three U.S. residents—120 million people—live in counties with unhealthy levels of air pollution, according to the  2023  State of the Air  report by the American Lung Association (ALA). Since the annual report was first published, in 2000, its findings have shown how the Clean Air Act has been able to reduce harmful emissions from transportation, power plants, and manufacturing.

Recent findings, however, reflect how climate change–fueled wildfires and extreme heat are adding to the challenges of protecting public health. The latest report—which focuses on ozone, year-round particle pollution, and short-term particle pollution—also finds that people of color are 61 percent more likely than white people to live in a county with a failing grade in at least one of those categories, and three times more likely to live in a county that fails in all three.

In rankings for each of the three pollution categories covered by the ALA report, California cities occupy the top three slots (i.e., were highest in pollution), despite progress that the Golden State has made in reducing air pollution emissions in the past half century. At the other end of the spectrum, these cities consistently rank among the country’s best for air quality: Burlington, Vermont; Honolulu; and Wilmington, North Carolina. 

No one wants to live next door to an incinerator, oil refinery, port, toxic waste dump, or other polluting site. Yet millions of people around the world do, and this puts them at a much higher risk for respiratory disease, cardiovascular disease, neurological damage, cancer, and death. In the United States, people of color are 1.5 times more likely than whites to live in areas with poor air quality, according to the ALA.

Historically, racist zoning policies and discriminatory lending practices known as  redlining  have combined to keep polluting industries and car-choked highways away from white neighborhoods and have turned communities of color—especially low-income and working-class communities of color—into sacrifice zones, where residents are forced to breathe dirty air and suffer the many health problems associated with it. In addition to the increased health risks that come from living in such places, the polluted air can economically harm residents in the form of missed workdays and higher medical costs.

Environmental racism isn't limited to cities and industrial areas. Outdoor laborers, including the estimated three million migrant and seasonal farmworkers in the United States, are among the most vulnerable to air pollution—and they’re also among the least equipped, politically, to pressure employers and lawmakers to affirm their right to breathe clean air.

Recently,  cumulative impact mapping , which uses data on environmental conditions and demographics, has been able to show how some communities are overburdened with layers of issues, like high levels of poverty, unemployment, and pollution. Tools like the  Environmental Justice Screening Method  and the EPA’s  EJScreen  provide evidence of what many environmental justice communities have been explaining for decades: that we need land use and public health reforms to ensure that vulnerable areas are not overburdened and that the people who need resources the most are receiving them.

In the United States, the  Clean Air Act  has been a crucial tool for reducing air pollution since its passage in 1970, although fossil fuel interests aided by industry-friendly lawmakers have frequently attempted to  weaken its many protections. Ensuring that this bedrock environmental law remains intact and properly enforced will always be key to maintaining and improving our air quality.

But the best, most effective way to control air pollution is to speed up our transition to cleaner fuels and industrial processes. By switching over to renewable energy sources (such as wind and solar power), maximizing fuel efficiency in our vehicles, and replacing more and more of our gasoline-powered cars and trucks with electric versions, we'll be limiting air pollution at its source while also curbing the global warming that heightens so many of its worst health impacts.

And what about the economic costs of controlling air pollution? According to a report on the Clean Air Act commissioned by NRDC, the annual  benefits of cleaner air  are up to 32 times greater than the cost of clean air regulations. Those benefits include up to 370,000 avoided premature deaths, 189,000 fewer hospital admissions for cardiac and respiratory illnesses, and net economic benefits of up to $3.8 trillion for the U.S. economy every year.

“The less gasoline we burn, the better we’re doing to reduce air pollution and the harmful effects of climate change,” Walke explains. “Make good choices about transportation. When you can, ride a bike, walk, or take public transportation. For driving, choose a car that gets better miles per gallon of gas or  buy an electric car .” You can also investigate your power provider options—you may be able to request that your electricity be supplied by wind or solar. Buying your food locally cuts down on the fossil fuels burned in trucking or flying food in from across the world. And most important: “Support leaders who push for clean air and water and responsible steps on climate change,” Walke says.

• “When you see in the news or hear on the weather report that pollution levels are high, it may be useful to limit the time when children go outside or you go for a jog,” Walke says. Generally, ozone levels tend to be lower in the morning.
• If you exercise outside, stay as far as you can from heavily trafficked roads. Then shower and wash your clothes to remove fine particles.
• The air may look clear, but that doesn’t mean it’s pollution free. Utilize tools like the EPA’s air pollution monitor,  AirNow , to get the latest conditions. If the air quality is bad, stay inside with the windows closed.
• If you live or work in an area that’s prone to wildfires,  stay away from the harmful smoke  as much as you’re able. Consider keeping a small stock of masks to wear when conditions are poor. The most ideal masks for smoke particles will be labelled “NIOSH” (which stands for National Institute for Occupational Safety and Health) and have either “N95” or “P100” printed on it.
• If you’re using an air conditioner while outdoor pollution conditions are bad, use the recirculating setting to limit the amount of polluted air that gets inside.

Air pollution is high on the global agenda and is widely recognised as a threat to both public health and economic progress. The World Health Organization (WHO) estimates that 4.2 million deaths annually can be attributed to outdoor air pollution. Recently, there have been major advances in methods that allow the quantification of air pollution-related indicators to track progress towards the Sustainable Development Goals and that expand the evidence base of the impacts of air pollution on health. Despite efforts to reduce air pollution in many countries there are regions, notably Central and Southern Asia and Sub-Saharan Africa, in which populations continue to be exposed to increasing levels of air pollution. The majority of the world’s population continue to be exposed to levels of air pollution substantially above WHO Air Quality Guidelines and, as such, air pollution constitutes a major, and in many areas, increasing threat to public health.

Health impacts of air pollution exposure from 1990 to 2019 in 43 European countries

Introduction.

In 2016, the WHO estimated that 4.2 million deaths annually could be attributed to ambient (outdoor) fine particulate matter air pollution, or PM 2.5 (particles smaller than 2.5 μm in diameter) 1 . PM 2.5 comes from a wide range of sources, including energy production, households, industry, transport, waste, agriculture, desert dust and forest fires and particles can travel in the atmosphere for hundreds of kilometres and their chemical and physical characteristics may vary greatly over time and space. The WHO developed Air Quality Guidelines (AQG) to offer guidance for reducing the health impacts of air pollution. The first edition, the WHO AQG for Europe, was published in 1987 with a global update (in 2005) reflecting the increased scientific evidence of the health risks of air pollution worldwide and the growing appreciation of the global scale of the problem 2 . The current WHO AQG states that annual mean concentration should not exceed 10 μg/m 3  2 .

The adoption and implementation of policy interventions have proved to be effective in improving air quality 3 , 4 , 5 , 6 , 7 . There are at least three examples of enforcement of long-term policies that have reduced concentration of air pollutants in Europe and North America: (i) the Clean Air Act in 1963 and its subsequent amendments in the USA; (ii) the Convention on Long-range Transboundary Air Pollution (LRTAP) with protocols enforced since the beginning of the 1980s in Europe and North America 8 ; and (iii) the European emission standards passed in the European Union in the early 1990s 9 . However, between 1960 and 2009 concentrations of PM 2.5 globally increased by 38%, due in large part to increases in China and India, with deaths attributable to air pollution increasing by 124% between 1960 and 2009 10 .

The momentum behind the air pollution and climate change agendas, and the synergies between them, together with the Sustainable Development Goals (SDGs) provide an opportunity to address air pollution and the related burden of disease. Here, trends in global air quality between 2010 and 2016 are examined in the context of attempts to reduce air pollution, both through long-term policies and more recent attempts to reduce levels of air pollution. Particular focus is given to providing comprehensive coverage of estimated concentrations and obtaining (national-level) distributions of population exposures for health impact assessment. Traditionally, the primary source of information has been measurements from ground monitoring networks but, although coverage is increasing, there remain regions in which monitoring is sparse, or even non-existent (see Supplementary Information) 11 . The Data Integration Model for Air Quality (DIMAQ) was developed by the WHO Data Integration Task Force (see Acknowledgements for details) to respond to the need for improved estimates of exposures to PM 2.5 at high spatial resolution (0.1° × 0.1°) globally 11 . DIMAQ calibrates ground monitoring data with information from satellite retrievals of aerosol optical depth, chemical transport models and other sources to provide yearly air quality profiles for individual countries, regions and globally 11 . Estimates of PM 2.5 concentrations have been compared with previous studies and a good quantitative agreement in the direction and magnitude of trends has been found. This is especially valid in data rich settings (North America, Western Europe and China) where trends results are consistent with what has been found from the analysis of ground level PM 2.5 measurements.

Figure 1a shows average annual concentrations of PM 2.5 for 2016, estimated using DIMAQ,; and Fig. 1b the differences in concentrations between 2010 and 2016. Although air pollution affects high and low-income countries alike, low- and middle-income countries experience the highest burden, with the highest concentrations being seen in Central, Eastern Southern and South-Eastern Asia 12 .

a Concentrations in 2016. b Changes in concentrations between 2010 and 2016.

The high concentrations observed across parts of the Middle East, parts of Asia and Sub-Saharan regions of Africa are associated with sand and desert dust. Desert dust has received increasing attention due to the magnitude of its concentration and the capacity to be transported over very long distances in particular areas of the world 13 , 14 . The Sahara is one of the biggest global source of desert dust 15 and the increase of PM 2.5 in this region is consistent with the prediction of an increase of desert dust due to climate change 16 , 17 .

Globally, 55.3% of the world’s population were exposed to increased levels of PM 2.5 , between 2010 and 2016, however there are marked differences in the direction and magnitude of trends across the world. For example, in North America and Europe annual average population-weighted concentrations decreased from 12.4 to 9.8 μg/m 3 while in Central and Southern Asia they rose from 54.8 to 61.5 μg/m 3 . Reductions in concentrations observed in North America and Europe align with those reported by the US Environmental Protection Agency and European Environmental Agency (EEA) 18 , 19 . The lower values observed in these regions reflect substantial regulatory processes that were implemented thirty years ago that have led to substantial decreases in air pollution over previous decades 18 , 20 , 21 . In high-income countries, the extent of air pollution from widespread coal and other solid-fuel burning, together with other toxic emissions from largely unregulated industrial processes, declined markedly with Clean Air Acts and similar ‘smoke control’ legislation introduced from the mid-20th century. However, these remain important sources of air pollution in other parts of the world 22 . In North America and Europe, the rates of improvements are small reflecting the difficulties in reducing concentrations at lower levels.

Assessing the health impacts of air pollution requires detailed information of the levels to which specific populations are exposed. Specifically, it is important to identify whether areas where there are high concentrations are co-located with high populations within a country or region. Population-weighted concentrations, often referred to as population-weighted exposures, are calculated by spatially aligning concentrations of PM 2.5 with population estimates (see Supplementary Information).

Figure 2 shows global trends in estimated concentrations and population-weighted concentrations of PM 2.5 for 2010–2016, together with trends for SDG regions (see Supplementary Fig. 1.1 ). Where population-weighted exposures are higher than concentrations, as seen in Central Asia and Southern Asia, this indicates that higher levels of air pollution coincide with highly populated areas. Globally, whilst concentrations have reduced slightly (from 12.8 μg/m 3 in 2010 to 11.7 in 2016), population-weighted concentrations have increased slightly (33.5 μg/m 3 in 2010, 34.6 μg/m 3 in 2016). In North America and Europe both concentrations and population-weighted concentrations have decreased (6.1–4.9 and 12.4–9.8 μg/m 3 , respectively). The association between concentrations and population can be clearly seen for Central Asia and Southern Asia where concentrations increased from 29.6 to 31.7 μg/m 3 (a 7% increase) while population-weighted concentrations were higher both in magnitude and in percentage of increase, increasing from 54.8 to 61.5 μg/m 3 (a 12% increase).

a Concentrations. b Population-weighted concentrations.

For the Eastern Asia and South Eastern Asia concentrations increase from 2010 to 2013 and then decrease from 2013 to 2016, a result of the implementation of the ‘Air Pollution Prevention and Control Action Plan’ 21 and the transition to cleaner energy mix due to increased urbanization in China 23 , 24 , 25 . Population-weighted concentrations for urban areas in this region are strongly influenced by China, which comprises 62.6% of the population in the region. Population-weighted concentrations are higher than the concentrations and the decrease is more marked (in the population-weighted concentrations), indicating that the implementation of policies has been successful in terms of the number of people affected. The opposite effect of population-weighting is observed in areas within Western Asia and Northern Africa where an increasing trend in population-weighted concentrations (from 42.0 to 43.1. μg/m 3 ) contains lower values than for concentrations (from 50.7 to 52.6 μg/m 3 ). In this region, concentrations are inversely correlated with population, reflecting the high concentrations associated with desert dust in areas of lower population density.

Long-term policies to reduce air pollution have been shown to be effective and have been implemented in many countries, notably in Europe and the United States. However, even in countries with the cleanest air there are large numbers of people exposed to harmful levels of air pollution. Although precise quantification of the outcomes of specific policies is difficult, coupling the evidence for effective interventions with global, regional and local trends in air pollution can provide essential information for the evidence base that is key in informing and monitoring future policies. There have been major advances in methods that expand the knowledge base about impacts of air pollution on health, from evidence on the health effects 26 , modelling levels of air pollution 1 , 11 and quantification of health impacts that can be used to monitor and report on progress towards the air pollution-related indicators of the Sustainable Development Goals: SDG 3.9.1 (mortality rate attributed to household and ambient air pollution); SDG 7.1.2 (proportion of population with primary reliance on clean fuels and technology); and SDG 11.6.2 (annual mean levels of fine particulate matter (e.g., PM 2.5 and PM 10 ) in cities (population weighted)) 1 . There is a continuing need for further research, collaboration and sharing of good practice between scientists and international organisations, for example the WHO and the World Meteorological Organization, to improve modelling of global air pollution and the assessment of its impact on health. This will include developing models that address specific questions, including for example the effects of transboundary air pollution and desert dust, and to produce tools that provide policy makers with the ability to assess the effects of interventions and to accurately predict the potential effects of proposed policies.

Globally, the population exposed to PM 2.5 levels above the current WHO AQG (annual average of 10 μg/m 3 ) has fallen from 94.2% in 2010 to 90.0% in 2016, driven largely by decreases in North America and Europe (from 71.0% in 2010 to 48.6% in 2016). However, no such improvements are seen in other regions where the proportion has remained virtually constant and extremely high (e.g., greater than 99% in Central, Southern, Eastern and South-Eastern Asia Sustainable Development Goal (SDG) regions. See Supplementary Information for more details).

The problem, and the need for solutions, is not confined to cities: across much of the world the vast majority of people living in rural areas are also exposed to levels above the guidelines. Although there are differences when considering urban and rural areas in North America and Europe, in the vast majority of the world populations living in both urban and rural areas are exposed to levels that are above the AQGs. However, in other regions the story is very different (see Supplementary Information Fig. 7.1 and Supplementary Information Sections 7 and 8), for example population-weighted concentrations in rural areas in the Central and Southern Asia (55.5 μg/m 3 ), Sub-Saharan Africa (39.1 μg/m 3 ), Western Asia and Northern Africa (42.7 μg/m 3 ) and Eastern Asia and South-Eastern Asia (34.3 μg/m 3 ) regions (in 2016) were all considerably above the AQG. From 2010 to 2016 population-weighted concentrations in rural areas in the Central and Southern Asia region rose by approximately 11% (from 49.8 to 55.5 μg/m 3 ; see Supplementary Information Fig. 7.1 and Supplementary Information Sections 7 and 8). This is largely driven by large rural populations in India where 67.2% of the population live in rural areas 27 . Addressing air pollution in both rural and urban settings should therefore be a key priority in effectively reducing the burden of disease associated with air pollution.

Attempts to mitigate the effects of air pollution have varied according to its source and local conditions, but in all cases cooperation across sectors and at different levels, urban, regional, national and international, is crucial 28 . Policies and investments supporting affordable and sustainable access to clean energy, cleaner transport and power generation, as well as energy-efficient housing and municipal waste management can reduce key sources of outdoor air pollution. Interventions would not only improve health but also reduce climate pollutants and serve as a catalyst for local economic development and the promotion of healthy lifestyles.

Assessment of trends in global air pollution requires comprehensive information on concentrations over time for every country. This information is primarily based on ground monitoring (GM) from 9690 monitoring locations around the world from the WHO cities database for 2010–2016. However, there are regions in this may be limited if not completely unavailable, particularly for earlier years (see Supplementary Information). Even in countries where GM networks are well established, there will still be gaps in spatial coverage and missing data over time. The Data Integration Model for Air Quality (DIMAQ) supplements GM with information from other sources including estimates of PM2.5 from satellite retrievals and chemical transport models, population estimates and topography (e.g., elevation). Specifically, satellite-based estimates that combine aerosol optical depth retrievals with information from the GEOS-Chem chemical transport model 29 were used, together with estimates of sulfate, nitrate, ammonium, organic carbon and mineral dust 30 .

The most recent release of the WHO ambient air quality database, for the first time, contains data from GM for multiple years, where available The version of DIMAQ used here builds on the original version 11 , 30 by allowing data from multiple years to be modelled simultaneously, with the relationship between GMs and satellite-based estimates allowed to vary (smoothly) over time. The result is a comprehensive set of high-resolution (10 km × 10 km) estimates of PM2.5 for each year (2010–2016) for every country.

In order to produce population-weighted concentrations, a comprehensive set of population data on a high-resolution grid (Gridded Population of the World (GPW v4) database 31 ) was combined with estimates from DIMAQ. In addition, the Global Human Settlement Layer 32 was used to define areas as either urban, sub-urban or rural (based on land-use, derived from satellite images, and population estimates). A further dichotomous classification of whether grid-cells within a particular country were urban or rural (allocating sub-urban as either urban or rural) was based on providing the best alignment (at the country-level) to the estimates of urban-rural populations produced by the United Nations 27 .

It is noted that the estimates from DIMAQ used in this article may differ slightly from those used in the WHO estimates of the global burden of disease associated with ambient air pollution 1 , and the associated estimates of air pollution related SDG indicators, due to recent updates in the database and further quality assurance procedures.

Essay on Air Pollution – Sample 1 (200 Words)

Air pollution is a serious issue and a cause for major concern in today’s world. A report published in 2014  by the World Health Organisation states that 4.21 million individuals died prematurely in 2012 as a result of air pollution. Air pollution existed much before humans, in the form of volcanic eruptions and forest fires. However, it became much more prevalent after the Industrial Revolution.

Rapid industrial growth, unregulated emissions and a host of other issues significantly contributed to the rise in air pollution. In some cases, the severity of air pollution reached an extent where government intervention was necessary. The Great Smog of London, 1952, was an extreme case of air pollution where visibility was severely hampered. It also caused a host of illnesses and the consequent deaths of countless civilians. In November 2017, the levels of air pollution in Delhi were ten times above the safe limits. For reference, the healthy air quality index is between 0 to 50, but during that particular time period, the air quality index hit 500+. This event is now called the Great Smog of Delhi.

An air quality index of 500 and above indicates that the air is heavily polluted and will cause irreversible lung damage and a host of other illnesses to everyone who is exposed to it. Therefore, to avoid such situations in the future, relevant actions must be implemented.

Essay on Air Pollution – Sample 2 (500 Words)

Air pollution may seem like the result of anthropological activities, however, it has been around even before humans evolved. Places which are naturally arid and have minimal vegetation are prone to dust storms. When this particulate matter is added to the air, it can cause health issues in animals exposed to the dust storms.

Furthermore, active volcanoes pump extremely large amounts of toxic plumes and particulate matter into the atmosphere. Wildfires also pump large amounts of carbon monoxide into the atmosphere and hamper photosynthesis for plants. Even animals, especially ruminants such as cows contribute to global warming by producing large quantities of methane, a greenhouse gas.

However, air pollution was never a major concern until the industrial revolution. Industries grew rapidly, untreated emissions were pumped into the atmosphere, and the rise of automobiles significantly contributed to air pollution. Such activities continued without any restrictions until they started to cause a wide range of repercussions.

In humans, air polluted with contaminants can cause a wide array of illnesses ranging from asthma and bronchitis the various forms of cancer. Air pollution is not only present outdoors; interior air pollution is also a great concern. Recent research has actually found credible evidence that room fresheners have the many compounds within them, some of which are classified carcinogens. This means some of those compounds present in the aerosol has the potential to cause some forms of cancer. Other sources of air pollution can include gases such as carbon monoxide and radon.

Radon, in particular, is quite alarming. It is an odourless, colourless gas that occurs naturally. It is found in the soil as Uranium, which breaks down and eventually turns into radon gas. Radon has limited repercussions on health if exposed to low concentrations, however, when this gas gets trapped indoor, the higher levels of concentration can have wreak havoc or ultimately be lethal. Radon is also reported to be released from building materials such as granite. Exposure to radon causes no immediate health effects, but long term exposure has the potential to cause lung cancer.

Air pollution not only affects the lungs but the central nervous system too. It has been linked to a lot of diseases such as schizophrenia and autism. A study also implied that it can cause short-term memory losses or distortion of memory.

Historically, air pollution has caused many crises with the worst ever being the Bhopal Disaster in 1984. Fatalities were estimated at 3,800, with at least 600,000 injured. Next in severity was the Great Smog of 1952 which formed over London, killing an estimated 4,000 civilians over the course of four days.

Though measures have been taken to reduce the effects of air pollution, a lot of irreversible damage has been done. For instance, the effects of global warming have drastically increased; this is very apparent with the rise in sea levels and melting glaciers. If the ice caps continue to melt, then we will have to face drastic repercussions. Scientists have proposed a hypothetical scenario where the greenhouse effect becomes “uncontrolled.” Here, greenhouse gases build up and temperatures continue to rise steeply. Oceans will start to evaporate, adding more water vapour into the earth’s atmosphere. This intensifies the effect, reaching a point where temperatures are sufficiently high for rocks start sublimating. Though this scenario is hypothetical, some speculate that this phenomenon already occurred on Venus. The supporters of this theory back this up by claiming Venus has an atmosphere composed primarily of carbon dioxide. The theory also explains why Venus has an extremely high surface temperature of 462 degrees Celcius; which is in fact, the hottest planet in the solar system.

Hence, we need to reduce our impact on the planet and make a conscious effort to reduce air pollution. Explore more essay topics or other fascinating concepts by registering at BYJU’S

Essay on Air Pollution for Students and Children

500+ words essay on air pollution.

Essay on Air Pollution – Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases . Moreover, the rapidly increasing human activities like the burning of fossil fuels, deforestation is the major cause of air pollution.

How Air Gets Polluted?

The fossil fuel , firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree.

Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in the air .

Causes Of Air Pollution

Its causes include burning of fossil fuel and firewood, smoke released from factories , volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.

Besides, there are some other air pollutants like industrial waste, agricultural waste, power plants, thermal nuclear plants, etc.

Greenhouse Effect

The greenhouse effect is also the cause of air pollution because air pollution produces the gases that greenhouse involves. Besides, it increases the temperature of earth surface so much that the polar caps are melting and most of the UV rays are easily penetrating the surface of the earth.

Ways To Reduce Air Pollution

Although the level of air pollution has reached a critical point. But, there are still ways by which we can reduce the number of air pollutants from the air.

Reforestation- The quality of air can be improved by planting more and more trees as they clean and filter the air.

Policy for industries- Strict policy for industries related to the filter of gases should be introduced in the countries. So, we can minimize the toxins released from factories.

Use of eco-friendly fuel-  We have to adopt the usage of Eco-friendly fuels such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), bio-gas, and other eco-friendly fuels. So, we can reduce the amount of harmful toxic gases.

To sum it up, we can say that the air we breathe is getting more and more polluted day by day. The biggest contribution to the increase in air pollution is of fossil fuels which produce nitric and sulphuric oxides. But, humans have taken this problem seriously and are devotedly working to eradicate the problem that they have created.

Above all, many initiatives like plant trees, use of eco-friendly fuel are promoted worldwide.

Air Pollution Essay for Students in English: 100, 200 and 500 Words

Air pollution is becoming a serious issue that’s affecting human health, flora and fauna and overall well-being of Earth. As responsible citizens of the world, it’s our duty to take care of anything that’s harming the planet and leave it in better condition for future generations. Here are a few sample essays children can use to write about air pollution and learn about different ways to mitigate this crisis.

100 Words Essay on Air Pollution

200 words essay on air pollution, 500 words essay on air pollution.

Any physical, chemical, or biological alteration in the air is referred to as air pollution. The atmosphere contains a specific portion of the gas. It is harmful to survival to change the makeup of these gases. “Global warming” is the term used to describe the rise in global temperature caused by this imbalance in gas composition. Hazardous pollutants, whether present naturally or artificially, can modify the environment and have a negative impact on the ecosystem. Ineffective resource management and reckless human activity are harming the environment and therefore it is our responsibility as inhabitants of Earth to take care of it.

Pollution is any activity that tampers with the environment's fundamental characteristics and causes damage. The air we breathe is no longer clean and fresh, it has been contaminated by pollutants. The threat to Earth and its ecosystem is getting worse as a result of the contamination of the air, water, and soil. These pollutants are causing a number of respiratory and cardiovascular diseases—our immune system is getting affected negatively, and children are at a high risk of developing asthma and other breathing problems. There are numerous factors that frequently increase this air pollution. Automobiles, transportation methods, industrialization, expanding cities, etc. are the main causes of air pollution. The contamination of the entire atmosphere is brought on by the release of various toxic gases or dangerous components from such sources.

Air pollution, which has a negative impact on the environment, also has a significant impact on the ozone layer. The primary contributor to pollution is the ever-increasing demands of the human population. Daily human activities pump harmful chemicals into the atmosphere, making it more polluted than ever and accelerating climate change. The flora and fauna are also being severely impacted by the airborne harmful chemical releases. The rising contamination of the Earth's air, water, and soil—the essential life support systems of the planet—poses a major threat to the planet and its environment.

One of today's top environmental concerns is air pollution. There are numerous factors that frequently increase this air pollution. Toxic gases, particulates, paint, and batteries containing lead are released throughout the industrialization process. The ozone layer is also being destroyed and the world is being exposed to dangerous solar rays as a result of all the contaminants in touch with the atmosphere.

Ozone is a contaminant that exists at the ground level and can be harmful to human health. But the same ozone creates a layer of defence in the stratosphere. The "good" ozone, however, is being destroyed by ozone-depleting substances—such as hydrochlorofluorocarbons, and chlorofluorocarbons. These chemicals were once used in coolants, foaming agents, insecticides, solvents, and fire extinguishers and occasionally still are.

Primary and secondary pollutants are the two categories that have emerged as a result of the growing number of air pollutants. Primary pollutants, which include smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, and radioactive substances, have a direct negative impact on fresh air. Secondary pollutants are those that interact chemically with primary pollutants, as well as other elements in the atmosphere, such as sulphate trioxide, ozone, hydrocarbons, and nitrogen dioxide.

Causes of Air Pollution

The disposal of solid wastes that release methane gas and the breakdown of trash landfills are major sources of air pollution. This problem has become a severe environmental and health issue as a result of the population's rapid development, industrialisation, and greater use of cars, planes, and other transportation.

Common Effects of Air Pollution

Pollutants in the air we breathe every minute enter our bloodstream and travel to our lungs and entire body, producing a plethora of health issues. Animals can have health issues similar to people if they are exposed to air toxics in high enough quantities over an extended period of time. Air toxics also play a role in animal sickness, infertility, and birth abnormalities. Therefore, both directly and indirectly, pollution of the environment harms both plants, animals, and people.

What Can We Do

Using public transportation is a surefire short method to reduce air pollution because it uses less gas and electricity, even carpools help with the situation. A permanent, non-polluting, and extremely secure source of energy is the sun or solar power. Solar panels, which are special in design and simple to install, are also a technical benefit to society and the planet. They take in solar energy and store it to power various equipment and electronics. Another step you can take on this path is to plant more trees and live a simplistic life. Minimalist living is not only a trendy millennial lifestyle, but it also has significant societal and environmental benefits.

Air pollution may reach one million tonnes annually in the next decades if environmental protection measures are not taken seriously and effectively enforced. We need to drastically alter our everyday routines if we want to lower the level of air pollution. By making better use of raw materials, water energy, and other resources, we can reduce pollution. Human health can be safeguarded and economic wellbeing can be increased when less harmful compounds are exchanged for hazardous ones.

Global Air Pollution

Introduction.

Air pollution is a global issue that requires international collaborating and cooperating. Statistics reveal that human activities produce a tremendous amount of contaminating substances. These processes also cause climate change and global warming. The purpose of this paper is to summarize the video that describes the issues of air quality and climate change and discuss these problems to highlight the main aspects.

The Quality of the Air

Our atmosphere is composed of various gases like nitrogen, oxygen, argon, carbon dioxide, neon, helium, and others. However, nitrogen and oxygen make up most of the air. The air quality has a significant impact on people’s health as the average person breathes in over 3000 gallons of air per day. Approximately a quarter of the US’s population resides in areas that do not meet environmental requirements. Different chronic diseases are caused by low-quality air. Some of them are asthma, lung diseases, and cancer. In addition, air pollution contributes to high death rates. It also affects the environment, causing acid rains and climate change.

One of the essential gases is nitrogen as it is necessary for crops to grow. However, nitrogen fertilizers that are widely used in the farm industry contaminate the environment. Oxygen is needed by all plants, animals, and humans. During respiration, it is converted to carbon dioxide that is used by plants for photosynthesis. Another important component of our atmosphere is ozone. Our planet has the ozone layer that protects the Earth from UV rays. However, there are many ozone holes caused by the use of CFC’s and refrigerants. Due to these ozone holes, the level of radiation in the atmosphere has increased. There is a technological solution to this issue. New types of gases that do not affect the ozone layer have been invented and are widely used instead of CFC’s and other refrigerants.

There are six criteria pollutants defined by EPA. These are sulfur dioxide, NOX, methane, lead, ozone, and particulate matter. The main sources of these contaminators are factories, electric utilities, power plants, and automobiles. The effect of thermal inversion causes forming a dense cool layer of air near the earth with warmer air above that catches pollutants. Thermal inversion traps mass of smog, pollution, and dirty city air.

Another important aspect is the greenhouse effect. It is a natural process in which some of the sun’s energy reaches the earth’s surface. It regulates the temperature, making our planet livable. However, greenhouse gases emitted by people’s activities increase the greenhouse effect that causes global climate change. This is manifested in the rise in sea level, flooding on coastlines, and the spread of diseases.

There are many laws that regulate the level of air pollution in the US. The Air Pollution Control Act of 1955, the Clean Air Act of 1963, the Motor Vehicle Pollution act of 1965, and other normative acts were established to set the standards of air quality. Due to these acts, the emission of mentioned above pollutants decreased by 60%.

Some changes relating to improving air quality were made on a federal level as well. Bush, Obama, and Trump administrations issued several acts that regulate the operating of power plants and motor vehicles. However, some programs failed to comply with international standards.

Air quality is a prominent issue and certain measures are to be taken. Socioeconomic changes made automobiles highly affordable. The number of cars on the road has dramatically increased, and now automobiles are the greatest polluter. Therefore, it has become necessary to switch the entire transportation regime. However, there are other important pollution reduction strategies like voluntary actions by industries and open burning laws. Hence, it is necessary to make more efforts to implement such methods throughout the world.

Air pollution came into being with an increase in the level of carbon dioxide, with the increase in pollutants which are contaminating the air and causing breathing discomfort as well as skin diseases to human beings. Talking about the other aspect, there is no life without water.

The water bodies are polluting and becoming unsafe for drinking or any other use because of industrial development, rapid urbanisation and various other reasons. Due to air pollution, diseases that can occur in human beings are asthma, various skin diseases, cancer, etc. Therefore, it is the essential need of the hour to take serious steps to reduce pollution to its core.

At a personal level, we can minimise environmental pollution by taking public transport or carpools to reduce vehicular smoke, avoiding firecrackers at festivals and celebrations can also cut down on air and noise pollution, and not using fertilisers and pesticides which can cause both water and soil pollution, and switching over to organic farming. The government can also bring strict rules and regulations to lessen industrial pollution.  

To sum up, any type of pollution is harmful to the environment with serious consequences like global warming, uneven climatic changes, etc. Due to our greediness and illegal human activities, the innocent lives of animals are lost. The time has come to join hands and work towards preserving and protecting the environment for the present as well as future generations.

Some people think that it does not exist, often saying that it’s a scam from a certain group of individual or even the government to get their hard earn […]

About Air, Water and Soil Pollution

Air Pollution What health hazards are associated with living indoors? Indoor air pollution can cause big health problems. People who may be exposed to these indoor air pollutants for long periods of time are most at risk to the effects of air pollution. This includes children, adults, and people with long term chronic illnesses. Most indoor air pollution comes from sources that release gases into the air. Things such as air fresheners, and building materials constantly give off air pollution. […]

The Impact of Wildfires on Air Pollution and Human Health

Climate change has many consequences. Some of the most well-known consequences include rising sea levels and increasing temperatures. However, one of the less studied consequences of climate change is the increasing frequency and intensity of wildfires that are occurring due to a drier and warmer climate.8 Therefore, vegetation in those climates lose more water and the amount of dry fuel in the environment will increase. Wildfires that occur due to climate change can also spread faster as climate change has […]

Can you stay without light in your life?! Our environment is our light. God created the surroundings in their most beautiful form, but when a shadow got here over this light, our surroundings grew to become darkish and this shadow is us. The environment includes the living and non-living things that an organism interacts with or has an impact on it. Living elements that an organism interacts with are known as biotic elements: animals, plants, etc., abiotic elements are non-living […]

Air Pollution and Health

Air pollution is an evident mater that is only getting worse as time goes on. This is an issue that affects everyone, and it has been proven several times that poor air quality is severely damaging to people's health and wellbeing. There are several things that contribute to air pollution, even things that humans do on a day to day basis. It is imperative that we do all in our power to limit the pollution of our air in order […]

What you Need to Know about Air Pollution

With climate change becoming a major area of concern across the globe, air pollution is a topic that needs to be a closely paid attention to. Globally, cities track and report the air pollution that is produced within their area. To better fix and ideally prevent the air pollution issues in the world, cities are beginning to take steps to improve the air quality that its citizens are breathing daily. Air pollution is a mixture of solid particles and gas […]

Air Pollution and Environmental Quality

Environment refers to the surroundings. These could either be people, houses, factories or anything visible. Policy, on the other hand, is a term used to point out at rules or guidelines set to govern or protect something. In this case, the rules are set to guide the surrounding (Wu 184). Air pollution comes in when a surrounding gets overwhelmed by activities done by people in the name of earning a living (Knox 173). Human activities result in the emission of […]

Air Pollution in Houston

Introduction Houston has been facing an air pollution problem which affects our daily lives. With the establishment of numerous companies and refineries, the smoke and chemicals from them, and the enormous amount of automobile usage contribute to air pollution. The quality of air that Houstonians have been inhaling is detrimental to their health and it consequently places them at risk of suffering from major diseases like asthma, heart disease, and stroke. Although many controls have been considered to reduce air […]

During the Industrial Revolution

During the Industrial Revolution the urbanization of cities and the rise in factories in the US contributed to environmental damage and the health hazards of humans through pollution. This quote, Industries discharged foul, sometimes toxic, solid, liquid, and gaseous wastes into the surrounding air, water, and land (Rosen, 565) tells us how unregulated factories expelled dangerous wastes into the ecosystem without being treated to be harmless. During the Industrial Revolution the lifestyle of Americans in the US changed and population […]

Air Pollution in Vietnam Today

The development of technologies and the demands of human beings are creating severe problems to our planet. Global warming and polluted environment are being reinforced due to the human activities. This is also occurring in my country. Vietnam is developing, so the processes of industrialization are strongly pushed by my government. Tons of gas and industrial waste are emitted to the sky and into the sea. Also, the exploited activities in the forest and ocean are ruining a lot habitats […]

Impact of Air Pollution on Human Health

The quality of the air influences a lot in people lives. Living in an environment free of pollution supposes a better quality of life. In most cases we do not even know the way in which this pollution affects us. According to the World Health Organization website, because air pollution, around 7 million people died (7 million premature death). The growth of our population, the way in which energy is consumed, transportation, the air-conditioned systems, and others cause the emission […]

Solution to Air Pollution and Environmental Degradation

Introduction In his book, The Ocean of Life, Callum Roberts states, 'Our failure to notice creeping environmental degradation has compromised more than our quality of life.' This is one of many warnings that have been relayed throughout the news, movies, and even children's books, such as Doctor Seuss's The Lorax. These cautionary tales warn us to respect our planet and come together to find solutions. Unfortunately, our ever-growing population, constant consumption of non-renewable resources, poor waste management practices, and over-use […]

Catastrophic Effect of the Pollution in the World

Pollution has a catastrophic effect in the world today and our future. Its caused by the process of making new land, water , air or other parts of the environment that are unsanitary and not able to be used. Simple abiotic factors such as light, sound, and temperature can be considered as a pollutants once they are initiated artificially into an environment. There are three different types of pollution today land, air and water. A pollutant that is most common […]

Essay About Air Pollution Air pollution is a type of environmental pollution that affects the air and mostly happens because of smoke or other harmful gases, mainly oxides of carbon, sulphur, and nitrogen. It occurs when those gases are introduced into the atmosphere in a way that makes it harmful to humans, animals, and plant. One of the biggest things that cause air pollution are cars, every time you see that smoke that comes from below your car's exhaust pipe, you see air pollution. Air pollution refers to the presence of foreign substances in the air that doesn’t belong there or excessive amounts of certain impurities that wouldn't harm us otherwise. When cars burn gasoline, they emit pollutants. Gasoline fumes escape into the air even when we pump gasoline into our fuel tanks. There are a large number of pollutions that come from cares, the first one is when cars produce carbon monoxide. That happens when the carbon in fuel doesn't burn completely and ruins the air. Second, is when a car's exhaust emits hydrocarbons meaning a toxic compound of hydrogen and carbon. Last, When fuel burns, nitrogen and oxygen react with each other and form nitrogen oxides and that pollutes the air. The air pollution causes a lot of problems like global warming, climate change and it also ruins the environment. An example is that air pollution impacts the process of photosynthesis in many cases, with serious consequences for the purification of the air we breathe. A solution that was invented for air pollution from cars was the Tesla. Tesla is an American automotive and energy company based in California. The main difference between normal cars and Teslas is powering. If gas is the number one fuel for cars around the world, Tesla cars are using electricity as their fuel. This makes a huge impact on the environment pollution as electricity lives no trace whatsoever in the air and the noise is minimal. Aside from air pollution, cities are battling with enormous sound pollution, and if cars become powered by electricity globally, a lot of the environmental problems that I listed will be solved just with this change. Regular vehicles need constant oil checks and if the oil runs out, much of the car won’t function because almost all the parts of the car need some kind of oil. Tesla cars do not need oil at all. Tesla cars work with a powerful battery, which is charged with electricity. This gives juice for the car to run for a certain period of time. This battery is a little similar to the batteries that you can find in your laptop and smartphone, you charge it, it drives for a couple 100 kilometers and then you need to charge it again. Tesla uses lithium-ion batteries in order to power up their supercars. These batteries are extremely powerful. In fact, a battery that you can find in a Tesla car is made out of thousands of lithium-ion cells and weights at least a thousand pound. Tesla cars work with a small motor, which is about the size of a watermelon. This is one of the latest innovations in electronic engineering. It converts electrical energy drawn from the batteries to mechanical power in order to move the vehicle. This is a more efficient technology when compared to the combustion engines that you can find on traditional cars. In other words, people who drive Tesla cars will be able to get a longer range for their charge, which can help them to save money in the long run. In conclusion, I think that Teslas are one of the best solutions for air pollution right now. They don't use gas which helps the environment and decreases the possibilities of global warming which is a very dangerous thing in our world right now. Sure, they aren’t the perfect solution and I'm sure that better solutions will be made in the future or are in the making right now but Tesla is a simple easy solution that is accessible for a lot of people and it makes a big change in our world for the better.

The world’s 100 worst polluted cities are in Asia — and 83 of them are in just one country

A ll but one of the 100 cities with the world’s worst air pollution last year were in Asia, according to a new report , with the climate crisis playing a pivotal role in bad air quality that is risking the health of billions of people worldwide.

The vast majority of these cities — 83 — were in India and all exceeded the World Health Organization’s air quality guidelines by more than 10 times, according to the report by IQAir , which tracks air quality worldwide.

The study looked specifically at fine particulate matter, or PM2.5, which is the tiniest pollutant but also the most dangerous. Only 9% of more than 7,800 cities analyzed globally recorded air quality that met WHO’s standard, which says average annual levels of PM2.5 should not exceed 5 micrograms per cubic meter.

“We see that in every part of our lives that air pollution has an impact,” said IQAir Global CEO Frank Hammes. “And it typically, in some of the most polluted countries, is likely shaving off anywhere between three to six years of people’s lives. And then before that will lead to many years of suffering that are entirely preventable if there’s better air quality.”

When inhaled, PM2.5 travels deep into lung tissue where it can enter the bloodstream. It comes from sources like the combustion of fossil fuels, dust storms and wildfires, and has been linked to  asthma , heart and lung disease, cancer, and other respiratory illnesses, as well as cognitive impairment in children.

Begusarai, a city of half a million people in northern India’s Bihar state, was the world’s most polluted city last year with an average annual PM2.5 concentration of 118.9 — 23 times the WHO guidelines. It was followed in the IQAir rankings by the Indian cities of Guwahati, Assam; Delhi; and Mullanpur, Punjab.

Across India, 1.3 billion people, or 96% of the population, live with air quality seven times higher than WHO guidelines, according to the report.

Central and South Asia were the worst performing regions globally, home to all four of the most polluted countries last year: Bangladesh, Pakistan, India and Tajikistan.

South Asia is of particular concern, with 29 of the 30 most polluted cities in India, Pakistan or Bangladesh. The report ranked the major population centers of Lahore in 5th, New Delhi in 6th and Dhaka in 24th place.

Hammes said no significant improvement in pollution levels in the region is likely without “major changes in terms of the energy infrastructure and agricultural practices.”

“What’s also worrisome in many parts of the world is that the things that are causing outdoor air pollution are also sometimes the things that are causing indoor air pollution,” he added. “So cooking with dirty fuel will create indoor exposures that could be many times what you’re seeing outdoors.”

A global problem

IQAir found that 92.5% of the 7,812 locations in 134 countries, regions, and territories where it analyzed average air quality last year exceeded WHO’s PM2.5 guidelines.

Only 10 countries and territories had “healthy” air quality : Finland, Estonia, Puerto Rico, Australia, New Zealand, Bermuda, Grenada, Iceland, Mauritius and French Polynesia.

Millions of people die each year from air pollution-related health issues. Air pollution from fossil fuels is killing 5.1 million people worldwide every year, according to a study published in the BMJ in November. Meanwhile, WHO says 6.7 million people die annually from the combined effects of ambient and household air pollution.

The human-caused climate crisis, driven by the burning of fossil fuels, plays a “pivotal” role in influencing air pollution levels, the IQAir report said.

The climate crisis is altering weather patterns, leading to changes in wind and rainfall, which affects the dispersion of pollutants. Climate change will only make pollution worse as extreme heat becomes more severe and frequent, it said.

The climate crisis is also leading to more severe wildfires in many regions and longer and more intense pollen seasons, both of which exacerbate health issues linked to air pollution.

“We have such a strong overlap of what’s causing our climate crisis and what’s causing air pollution,” Hammes said. “Anything that we can do to reduce air pollution will be tremendously impactful in the long term also for improving our climate gas emissions, and vice versa.”

Regional rankings

North America was badly affected by wildfires that raged in Canada from May to October last year. In May, the monthly average of air pollution in Alberta was nine times greater than the same month in 2022, the report found.

And for the first time, Canada surpassed the United States in the regional pollution rankings.

The wildfires also affected US cities such as Minneapolis and Detroit, where annual pollution averages rose by 30% to 50% compared to the previous year. The most polluted major US city in 2023 was Columbus, Ohio for the second year running. But major cities like Portland, Seattle and Los Angeles experienced significant drops in annual average pollution levels, the report said.

In Asia, however, pollution levels rebounded across much of the region.

China reversed a five-year trend of declining levels of pollution, the report found. Chinese cities used to dominate global rankings of the world’s worst air quality but a raft of clean air policies over the past decade has transformed things for the better.

A study last year had found the campaign meant the average Chinese citizen’s lifespan is now 2.2 years longer. But thick smog returned to Beijing last year, where citizens experienced a 14% increase in the annual average PM2.5 concentration, according to the IQAir report. China’s most polluted city, Hotan, was listed at 14 in the IQAir ranking.

In Southeast Asia, only the Philippines saw a drop in annual pollution levels compared to the previous year, the report found.

Indonesia was the most polluted country in the region, with a 20% increase compared to 2022. Indonesia, Vietnam and Thailand all had cities that exceeded WHO PM2.5 guidelines by more than 10 times, according to the report.

Last month, Thai authorities ordered government employees to work from home due to unhealthy levels of pollution in the capital Bangkok and surrounding areas, according to Reuters. On Friday, tourism hot spot Chiang Mai was the world’s most polluted city as toxic smog brought by seasonal agricultural burning blanketed the northern city.

Inequality… and one bright spot

The report also highlighted a worrying inequality: the lack of monitoring stations in countries in Africa, South America and the Middle East, which results in a dearth of air quality data in those regions.

Although Africa saw an improvement in the number of countries included in this year’s report compared with previous years  the continent largely remains the most underrepresented. According to IQAir, only 24 of 54 African countries had sufficient data available from their monitoring stations.

Seven African countries were among the new locations included in the 2023 rankings, including Burkina Faso, the world’s fifth most polluted country, and Rwanda, in 15th.

Several countries that ranked high on the most polluted list last year were not included for 2023 due to a lack of available data. They include Chad, which was the most polluted country in 2022.

“There is so much hidden air pollution still on the planet,” said Hammes.

One bright spot is increasing pressure and civic engagement from communities, NGOs, companies, and scientists to monitor air quality.

“Ultimately that’s great because it really shows governments that people do care,” Hammes said.

Earth Day: How a senator’s idea more than 50 years ago got people fighting for their planet

Millions of people around the world will pause on Monday, at least for a moment, to mark Earth Day. It’s an annual event founded by people who hoped to stir activism to clean up and preserve a planet that is now home to some 8 billion humans and assorted trillions of other organisms.

Here are answers to some common questions about Earth Day and how it came to be:

WHY DO WE CELEBRATE EARTH DAY?

Earth Day has its roots in growing concern over pollution in the 1960s, when author Rachel Carson’s 1962 book “Silent Spring,” about the pesticide DDT and its damaging effects on the food chain, hit bestseller lists and raised awareness about nature’s delicate balance.

But it was a senator from Wisconsin, Democrat Gaylord Nelson, who had the idea that would become Earth Day. Nelson had long been concerned about the environment when a massive offshore oil spill sent millions of gallons onto the southern California coast in 1969. Nelson, after touring the spill site, had the idea of doing a national “teach-in” on the environment, similar to teach-ins being held on some college campuses at the time to oppose the war in Vietnam.

Nelson and others, including activist Denis Hayes, worked to expand the idea beyond college campuses, with events all around the country, and came up with the Earth Day name.

WHY WAS APRIL 22 CHOSEN FOR EARTH DAY?

A history of the movement by EarthDay.org, where Hayes remains board chair emeritus, says the date of the first Earth Day — April 22, 1970 — was chosen because it fell on a weekday between spring break and final exams and the aim was to attract as many students as possible.

IS EARTH DAY A REAL HOLIDAY?

It’s not a federal holiday. But many groups use the day to put together volunteer events with the environment in mind, such as cleanups of natural areas. You can see a list of events worldwide , or register your own event, at EarthDay.org.

HAS IT HAD AN IMPACT?

It has. The overwhelming public response to the first Earth Day is credited with adding pressure for the U.S. Congress to do more to address pollution, and it did, passing landmark legislation including the Clean Air Act and Clean Water Act. More broadly, it’s seen as the birth of the modern environmental movement. In later years, Earth Day expanded to become a truly global event. It now claims to have motivated action in more than 192 countries.

In 2000, Earth Day began taking aim at climate change, a problem that has grown rapidly more urgent in recent years.

WHAT’S THE THEME THIS YEAR?

This year’s Earth Day is focusing on the threat that plastics pose to our environment, with a call to end all single-use plastic and find replacements for their use so they can quickly be phased down.

‘Where can you hide from pollution?’: cancer rises 30% in Beirut as diesel generators poison city

Lebanon’s economy and electricity system are broken and much power is now generated locally, with devastating effects on air quality and health

S mog hangs over Beirut most days, a brownish cloud that darkens the city’s skyline of minarets and concrete towers. An estimated 8,000 diesel generators have been powering Lebanese cities since the nation’s economic collapse in 2019. The generators can be heard, smelled and seen on the streets, but their worst impact is on the air the city’s inhabitants are forced to breathe.

New research, to be published by scientists at American University of Beirut (AUB), has found that the Lebanese capital’s over-reliance on the diesel generators in the past five years has directly doubled the risk of developing cancer. Rates of positive diagnosis, oncologists say, are shooting up.

• A common condition

The human toll of non-communicable diseases (NCDs) is huge and rising. These illnesses end the lives of approximately 41 million of the 56 million people who die every year – and three quarters of them are in the developing world.

NCDs are simply that; unlike, say, a virus, you can’t catch them. Instead, they are caused by a combination of genetic, physiological, environmental and behavioural factors. The main types are cancers, chronic respiratory illnesses, diabetes and cardiovascular disease – heart attacks and stroke. Approximately 80% are preventable, and all are on the rise, spreading inexorably around the world as ageing populations and lifestyles pushed by economic growth and urbanisation make being unhealthy a global phenomenon.

NCDs, once seen as illnesses of the wealthy, now have a grip on the poor. Disease, disability and death are perfectly designed to create and widen inequality – and being poor makes it less likely you will be diagnosed accurately or treated.

Investment in tackling these common and chronic conditions that kill 71% of us is incredibly low, while the cost to families, economies and communities is staggeringly high.

In low-income countries NCDs – typically slow and debilitating illnesses – are seeing a fraction of the money needed being invested or donated. Attention remains focused on the threats from communicable diseases, yet cancer death rates have long sped past the death toll from malaria, TB and HIV/Aids combined.

'A common condition' is a Guardian series reporting on NCDs in the developing world: their prevalence, the solutions, the causes and consequences, telling the stories of people living with these illnesses.

Tracy McVeigh, editor

“The results are alarming,” says Najat Saliba, an atmospheric chemist who led the study. In the area of Makassed, one of the more densely populated parts of Beirut tested, levels of pollution from fine particulates – that is, less than 2.5 micrometres in diameter (PM2.5) – peaked at 60 micrograms a cubic metre, four times the 15 mcg/m³ level the World Health Organization says people should be not exposed to for more than 3-4 days a year.

Since 2017, the last time AUB took these measurements, the level of carcinogenic pollutants emitted into the atmosphere has doubled across three areas of Beirut. Saliba says calculations suggest cancer risk will have risen by approximately 50%.

“It’s directly related,” she says. “We calculate the cancer risk based on the carcinogen materials emitted from diesel generators, some of which are classified as category 1A carcinogens .”

Generators used to fill a three-hour gap in national grid provision. Then, in 2019, one of the world’s most catastrophic economic collapses since the mid-19th century began in Lebanon. Within months the state energy grid came close to collapse and the diesel generators took over. The explosion in August 2020 , which killed more than 200 people and devastated Beirut’s commercial port, further brought the country to its knees.

Anecdotally, oncologists in Beirut now estimate that general cancer rates have been rising by 30% annually since 2020. There is a common observation – although as yet no definite data – that patients are getting younger and the tumours more aggressive.

Hani Nassar runs a cancer support association in the name of his late wife, Barbara Nassar. In his office in Beirut he points to a box of Lynparza, used to treat ovarian cancer. It is one of the medications not subsidised by the health ministry and costs $6,000 for a month’s supply. His association supports 40 women and he sometimes has to share one box among all of them.

Money is the biggest problem facing cancer patients in Lebanon , he says. The crisis has wreaked chaos. The average public sector salary is about $150 a month, far below the cost of chemotherapy.

“We have a lot of cancer patients who have not even begun any treatment,” says Hani. “They just end up saying, ‘OK, I will die – I don’t want to deprive my family of our house, our car, etc, just to pay for this.’”

In 2023, Human Rights Watch reported that lack of a reliable power supply had affected people’s right to electricity, and pointed to the Lebanese government continually adopting policies that entrenched oil dependency even as nations around the world try to transition to renewable energy.

“Diesel importers exert great influence, primarily because of the overlap between the shareholders of these companies and the political establishment,” the report noted.

Saliba says generator-owners and fuel importers are “making a fortune from burning diesel inside the city and suffocating people”. In 2017, Lebanon imported around $900m (£720m) worth of diesel for generators. By 2022, that figure was reported to have jumped to $1.9bn .

Lebanon’s government, paralysed politically and failing to enact anti-corruption measures that could unlock a bailout deal from the International Monetary Fund, has frozen ministry budgets, affecting all areas of life.

The air pollution monitor network – funded by the EU – has been out of service since 2019.

Lebanon is stuck in a “big vicious cycle” Saliba says. “We are a very poor country now, so we keep asking for all this money. But the trend across all sectors – and everything the government has handled over the past 10 years – is to take the money, install what needs installing, and then leave it without operating costs or any willingness to put the effort in to keep it running.”

The billions of dollars pumped into Lebanon by various international donors for infrastructure projects have not corrected the most basic issues, she says: “There is still no clean air, water or soil. There is nothing to show for any of it.”

after newsletter promotion

Julien Jreissati from Greenpeace Middle East and North Africa says an inoperative air pollution monitor network is consistent with other environmental projects.

“At least it was used and was a useful source of information for a time,” Jreissati says. “Unlike in the waste-management sector – which has seen millions of dollars poured into infrastructure projects, by the EU and other funders, such as funding wastewater-treatment plants or recycling plants.”

Many of these internationally funded projects, he adds, were never operational and some were never connected to the wastewater network.

A 2020 Greenpeace study estimated that 2,700 people died prematurely in Lebanon because of air pollution in 2018 – the highest rate per capita in the Middle East, joint with Egypt. The report found that the economic cost of air pollution in Lebanon amounted to $1.4bn – 2% of its GDP. Now, with no systemic data, there is no way to estimate the premature deaths.

Oncologists interviewed by the Guardian were keen to stress that while diesel generators harm public health, there is no getting away from Lebanon’s tobacco consumption.

An estimated 70% of the adult population of Lebanon smoke regularly and 38% are full-time smokers.

Dr Fadlo Khuri, the president of AUB and an oncologist specialising in lung and neck cancer says what is happening in Beirut is “a confluence of circumstances”.

Lebanon only taxes imported tobacco products: a packet of 20 Marlboro Gold costs £2.20 (in the UK it costs about £15), while the local brand Cedars costs 60p for 20. The domestic tobacco industry, Khuri says dryly, is “probably the only remaining functional branch of the government, besides the armed forces”.

He also says the health effects caused by long-term exposure to the airborne carcinogens from the generators – such as emphysema, heart disease and cancers – could take years more to see.

“The AUB did measurements and mathematic modelling and found that 40% of daily exposure by people in Lebanon to airborne carcinogens comes from one source: diesel generators,” Khuri says. “You’re not going to see the impact of that on lung and neck and bladder cancer rates for years because these are diseases which take years of chronic exposure.”

For Pia Saadeh, 27, diagnosed with stage 2 breast cancer six months ago, the government does not take the link between Lebanon’s worsening environment and rising cancer rates seriously enough.

“Generators should be gone,” she says. “The government has to take back control over the electricity sector. Where can you hide from the pollution here? It’s in the water, it’s the air, it’s in what you eat, it’s everywhere.”

The Chinese lesson to India: how can air pollution make or break your economy?

Beijing and New Delhi have more in common than being two of the world’s most populated capital cities – extreme air pollution has blanketed both their skies.

While stories of air pollution in Delhi resemble “Beijing from 20 years ago” to climate policy expert Saurabh Jain-Punamiya, the Delhi problem has grown into a pan-India problem, with air pollution cutting almost six years off the life expectancy of the country’s residents…

…Whlie India can improve its air quality, Michael Greenstone, economics professor and director of the Energy Policy Institute at the University of Chicago, said it is challenging to “find regulatory tools that work and that are consistent with the urgent and vital need for continued, rapid economic growth.”

But moving to market-based approaches such as pollution markets or taxes has shown major promise.

Greenstone, whose research inspired the Air Quality Life Index (AQLI) which links air quality with life expectancy, has been involved in an “exciting” initiative by the state government of Gujarat called India Clean Air Markets.

Essentially, the government sets a cap on emissions but then allows industries to buy and sell permits to stay below that cap.

The state ran a randomised experiment where firms were either regulated under the existing rules or by the new cap and trade regulations. The new regulations came out as the clear winner.

“Pollution went down by 20 to 30 percent, and industries’ compliance costs went down,” Greenstone said.

“The current form of regulation is so costly for polluters,” he said. By India moving to a more environmentally conscious market approach, it can “facilitate faster economic growth by reducing the cost to industry.”

It is an approach that has been widely used in developed countries like the United States, but the Gujarat initiative has show it is also effective in India, according to Greenstone.

“There is a remarkable opportunity sitting there to be grabbed that will allow for faster economic growth and allow for people to live in a cleaner and healthier environment,” he said.

Providing information can also develop political will to address air quality, which is what Greenstone hopes to achieve with the AQLI, which uses satellite air quality data to form an index of average global life expectancy loss due to air pollution.

“Economic growth is great, but it is a limited measure,” he said, adding that “if you are making everyone sick” and reducing the length of lives, these are real human costs.
