Photo: Air pollution is obvious when it pours from a smokestack (chimney), but it's not always so easy to spot. This is an old photo of the kind of smoke that used to come from coal-fired power plants and, apart from soot (unburned carbon particles), its pollutants include sulfur dioxide and the greenhouse gas carbon dioxide. Thanks to tougher pollution controls, modern power plants produce only a fraction as much pollution. Modern pollution made by traffic consists of gases like nitrogen dioxide and "particulates" (microscopic soot and dust fragments) that are largely invisible.

What is air pollution?

Air pollution is a gas (or a liquid or solid dispersed through ordinary air) released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly, damage or disrupt some other aspect of the environment (such as making buildings crumble), or cause some other kind of nuisance (reduced visibility, perhaps, or an unpleasant odor).

Natural air pollution

Photo: Forest fires are a completely natural cause of air pollution. We'll never be able to prevent them breaking out or stop the pollution they cause; our best hope is to manage forests, where we can, so fires don't spread. Ironically, that can mean deliberately burning areas of forest, as shown here, to create firebreaks. Forests are also deliberately burned to regenerate ecosystems. Photo by courtesy of US Fish and Wildlife Service .

Top-ten kinds of air pollution Photo: Flying molecules—if you could see air pollution close up, this is what it would look like. Image courtesy of US Department of Energy. Any gas could qualify as pollution if it reached a high enough concentration to do harm. Theoretically, that means there are dozens of different pollution gases. It's important to note that not all the things we think of as pollution are gases: some are aerosols (liquids or solids dispersed through gases). In practice, about ten different substances cause most concern: Sulfur dioxide : Coal, petroleum, and other fuels are often impure and contain sulfur as well as organic (carbon-based) compounds. When sulfur (spelled "sulphur" in some countries) burns with oxygen from the air, sulfur dioxide (SO 2 ) is produced. Coal-fired power plants are the world's biggest source of sulfur-dioxide air pollution, which contributes to smog, acid rain, and health problems that include lung disease. [5] Large amounts of sulfur dioxide are also produced by ships, which use dirtier diesel fuel than cars and trucks. [6] Carbon monoxide : This highly dangerous gas forms when fuels have too little oxygen to burn completely. It spews out in car exhausts and it can also build up to dangerous levels inside your home if you have a poorly maintained gas boiler , stove, or fuel-burning appliance. (Always fit a carbon monoxide detector if you burn fuels indoors.) [7] Carbon dioxide : This gas is central to everyday life and isn't normally considered a pollutant: we all produce it when we breathe out and plants such as crops and trees need to "breathe" it in to grow. However, carbon dioxide is also a greenhouse gas released by engines and power plants. Since the beginning of the Industrial Revolution, it's been building up in Earth's atmosphere and contributing to the problem of global warming and climate change . [8] Nitrogen oxides : Nitrogen dioxide (NO 2 ) and nitrogen oxide (NO) are pollutants produced as an indirect result of combustion, when nitrogen and oxygen from the air react together. Nitrogen oxide pollution comes from vehicle engines and power plants, and plays an important role in the formation of acid rain, ozone and smog. Nitrogen oxides are also "indirect greenhouse gases" (they contribute to global warming by producing ozone, which is a greenhouse gas). [9] Volatile organic compounds (VOCs) : These carbon-based (organic) chemicals evaporate easily at ordinary temperatures and pressures, so they readily become gases. That's precisely why they're used as solvents in many different household chemicals such as paints , waxes, and varnishes. Unfortunately, they're also a form of air pollution: they're believed to have long-term (chronic) effects on people's health and they play a role in the formation of ozone and smog. VOCs are also released by tobacco smoke and wildfires. [10] Particulates : There are many different kinds of particulates, from black soot in diesel exhaust to dust and organic matter from the desert. Airborne liquid droplets from farm pollution also count as particulates. Particulates of different sizes are often referred to by the letters PM followed by a number, so PM 10 means soot particles of less than 10 microns (10 millionths of a meter or 10µm in diameter, roughly 10 times thinner than a thick human hair). The smaller ("finer") the particulates, the deeper they travel into our lungs and the more dangerous they are. PM 2.5 particulates are much more dangerous (they're less than 2.5 millionths of a meter or about 40 times thinner than a typical hair). In cities, most particulates come from traffic fumes. [11] Ozone : Also called trioxygen, this is a type of oxygen gas whose molecules are made from three oxygen atoms joined together (so it has the chemical formula O 3 ), instead of just the two atoms in conventional oxygen (O 2 ). In the stratosphere (upper atmosphere), a band of ozone ("the ozone layer") protects us by screening out harmful ultraviolet radiation (high-energy blue light) beaming down from the Sun. At ground level, it's a toxic pollutant that can damage health. It forms when sunlight strikes a cocktail of other pollution and is a key ingredient of smog (see box below). [12] Chlorofluorocarbons (CFCs) : Once thought to be harmless, these gases were widely used in refrigerators and aerosol cans until it was discovered that they damaged Earth's ozone layer. We discuss this in more detail down below. [13] Unburned hydrocarbons : Petroleum and other fuels are made of organic compounds based on chains of carbon and hydrogen atoms. When they burn properly, they're completely converted into harmless carbon dioxide and water ; when they burn incompletely, they can release carbon monoxide or float into the air in their unburned form, contributing to smog. Lead and heavy metals : Lead and other toxic "heavy metals" can be spread into the air either as toxic compounds or as aerosols (when solids or liquids are dispersed through gases and carried through the air by them) in such things as exhaust fumes and the fly ash (contaminated waste dust) from incinerator smokestacks. [14] What are the causes of air pollution?

Chart: Most of the world's major cities routinely exceed World Health Organization (WHO) air pollution guidelines, though progress is being made: you can see that the 2022 figures (green) show a marked improvement on the 2016 ones (orange) in almost every case. This chart compares annual mean PM 2.5 levels in 12 representative cities around the world with the recently revised (2021) WHO guideline value of 5μg per cubic meter (dotted line). PM 2.5 particulates are those smaller than 2.5 microns and believed to be most closely linked with adverse health effects. For more about this chart and the data sources used, see note [22] .

Photo: Smokestacks billowing pollution over Moscow, Russia in 1994. Factory pollution is much less of a problem than it used to be in the world's "richer" countries—partly because a lot of their industry has been exported to nations such as China, India, and Mexico.

What effects does air pollution have?

Acid rain—a closer look.

Photo: Acid rain can turn lakes so acidic that fish no longer survive. Picture courtesy of U.S. Fish and Wildlife Service Division of Public Affairs. Why does that matter? Pure water is neither acidic nor alkaline but completely neutral (we say it has an acidity level or pH of 7.0). Ordinary rainwater is a little bit more acidic than this with about the same acidity as bananas (roughly pH 5.5), but if rain falls through sulfur dioxide pollution it can turn much more acidic (with a pH of 4.5 or lower, which is the same acidity as orange or lemon juice). When acid rain accumulates in lakes or rivers, it gradually turns the entire water more acidic. That's a real problem because fish thrive only in water that is neutral or slightly acidic (typically with a pH of 6.5–7.0). Once the acidity drops below about pH 6.0, fish soon start to die—and if the pH drops to about 4.0 or less, all the fish will be killed. Acid rain has caused major problems in lakes throughout North America and Europe. It also causes the death of forests, reduces the fertility of soil, and damages buildings by eating away stonework (the marble on the US Capitol in Washington, DC has been eroded by acid-rain, for example). One of the biggest difficulties in tackling acid rain is that it can happen over very long distances. In one notable case, sulfur dioxide air pollution produced by power plants in the UK was blamed for causing acid rain that fell on Scandinavian countries such as Norway, producing widespread damage to forests and the deaths of thousands of fish in acidified lakes. The British government refused to acknowledge the problem and that was partly why the UK became known as the "dirty man of Europe" in the 1980s and 1990s. [18] Acid rain was a particular problem in the last 30–40 years of the 20th century. Thanks to the decline in coal-fired power plants, and the sulfur dioxide they spewed out, it's less of a problem for western countries today. But it's still a big issue in places like India, where coal remains a major source of energy. Global air pollution It's hard to imagine doing anything so dramatic and serious that it would damage our entire, enormous planet—but, remarkable though it may seem, we all do things like this everyday, contributing to problems such as global warming and the damage to the ozone layer (two separate issues that are often confused). Global warming Every time you ride in a car, turn on the lights, switch on your TV , take a shower, microwave a meal, or use energy that's come from burning a fossil fuel such as oil, coal, or natural gas, you're almost certainly adding to the problem of global warming and climate change: unless it's been produced in some environmentally friendly way, the energy you're using has most likely released carbon dioxide gas into the air. While it's not an obvious pollutant, carbon dioxide has gradually built up in the atmosphere, along with other chemicals known as greenhouse gases . Together, these gases act a bit like a blanket surrounding our planet that is slowly making the mean global temperature rise, causing the climate (the long-term pattern of our weather) to change, and producing a variety of different effects on the natural world, including rising sea levels.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Air Lecture 2

Dr. IEcheverry, CAMS, KSU, 2nd3637 Objectives • Define • Air • Air pollution • Identify the different forms of air pollution • Identify the determinants of indoor and outdoor air quality • Identify common air pollutants • Identify the effects of air pollution on human health and the environment

Dr. IEcheverry, CAMS, KSU, 2nd3637 Introduction Air supplies the oxygen essential to human life. • Pure air is a mixture of several gases that are invisible and odorless. Middlecamp CH et al. Chemistry in Context: Applying Chemistry to Society. 7th Ed. McGrawHill. 2012

Dr. IEcheverry, CAMS, KSU, 2nd3637 Introduction Older people are more likely to suffer from cardiovascular disease and impairment of immune response. Increased susceptibility to air pollutants, especially fine particulates. • Humans may survive for up to three (3) minutes without air. • Adults ~ 12-20 breaths/min • Children ~ 15-30 breaths/min • Infants ~ 25-50 breaths/min • Children have higher respiratory rates and may receive higher doses of pollutants relative to their body weight. • Children’s respiratory systems are still maturing and are more susceptible to the effects of polluted air. Levy, B. et al. Occupational and Environmental Health. 2006. Lippincott Williams & Wilkins.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Introduction Atmosphere The bottom two kilometers of the troposphere contain most of the air and weather (rain, clouds, wind) that affect us, along with most air pollutants. • Mixture of gases that surround the earth. • Sustains life by retaining heat and blocking out harmful radiation (ultraviolet radiation) from the sun. • The troposphere is the layer closest to the earth and the thinnest. BC Air Quality http://www.bcairquality.ca/101/what-is-air-quality.html

Dr. IEcheverry, CAMS, KSU, 2nd3637 Air pollution • The presence of substances not normally found in air, and that in concentrations high enough can harm the environment, or the health of living organisms.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Air pollutants Gases and vapors: form true solutions in the air and cannot be distinguished from the air. Aerosols: dispersions of solid or liquid particles in the air. • Air pollutants can be gases, liquids (vapor) or very small solid particles (dust or smoke) emitted into the atmosphere. • At levels harmful to the environment, or human, animal and plant health.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Emissions Airshed – geographic area that shares the same air. • Discharges of a pollutant from a particular source (a factory) or group of sources (vehicles) into the air.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Emission Sources 1. Natural and Man-made Sources 2. Point and Non-point Sources Point – single, largestationary sources of pollution –industrial facilities, power plants. Non-point – multiple, smaller sources that can be stationary or mobile: motor vehicles, airplanes, residential and business areas.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Types of emissions Anthropogenic - come from man-made sources. Chlorofluorocarbons (CFCs), CO2. Human activity can also influence geogenic and biogenic emissions. Agriculture, deforestation, construction. • Geogenic - come from the non-living world, such as volcanic emissions, soil emissions, and natural fires. • Smoke, SO2, CO2. • Biogenic - come from the living world: plants, animals, microbes, soil. • VOCs and CH4 . http://www.envirocomp.org/books/chapters/1aap.pdf Daly, A. and P. Zannetti. 2007. An Introduction to Air Pollution – Definitions, Classifications, and History. Chapter 1 of AMBIENT AIR POLLUTION (P. Zannetti, D. Al-Ajmi, and S. Al-Rashied, Editors). Published by The Arab School for Science and Technology (ASST) (http://www.arabschool.org.sy) and The EnviroComp Institute (http://www.envirocomp.org/).

Dr. IEcheverry, CAMS, KSU, 2nd3637 Air Quality Poor air quality occurs when substances that are not normal components of the air (pollutants) are present in amounts that can harm human health or the environment. Pollutants can come from natural or man-made sources. • The state of the surrounding air. • Good air quality = clean, clear, unpolluted air. BC Air Quality http://www.bcairquality.ca/101/what-is-air-quality.html

Dr. IEcheverry, CAMS, KSU, 2nd3637 Factors Affecting Air Quality 1. The amountof pollutants 2. Thetypeof pollutants released into the air. • Physical and chemical propertiesof pollutants. 3. Topography(geography of the terrain) - mountains and valleys. 4. Weather- wind, temperature, air turbulence, air pressure, rainfall and cloud cover.

Dr. IEcheverry, CAMS, KSU, 2nd3637 Types of air pollutants Secondary pollutants are the products of chemical reactions between pollutants in the air. Secondary acidic aerosols and other particles. Oxidant pollutants produced by photochemical reactions between hydrocarbons and nitrogen oxides. Ground-level ozone is a secondary pollutant. • Primary pollutantsare emitted directly into the atmosphere. • Sulfur dioxide, nitrogen oxides, particles.

Table of contents.

To live, we need to breathe. To breathe, we need fresh air. Fresh air is one of the basic and essential things we need to live on earth. Fresh air is equally important to every one us as food and water. Even plants need oxygen to convert food into energy. From these things, we can understand the importance of oxygen and fresh air. A place without oxygen will be a dead zone with no humans, animals, and plants. Without oxygen, nobody can survive on earth.

All these facts point the fingers at the importance of keeping air pollution-free. But the truth is, the air is getting polluted at a massive rate every day. There are hundreds of causes. In these, there are some which are very harmful to us. But how can we reduce the rate of air pollution? Well, there are different ways that we could try to stop air pollution. Before that, let us find out what are the utmost causes of air pollution. Here are they. 

What Do We Mean By Air Pollution?

It’s simple. Air pollution refers to the release of pollutants into the air like Nitrogen Oxide, Volatile Organic Compounds, Carbon Dioxide, Sulphur Oxide, dioxins, and other harmful gases. Once these gases are released, they become a colossal threat to the environment and human health.

How Do We Know the Quality of Air?

The purity of air measured using an AQI thermometer that runs on a scale from 0 to 500. The AQI refers to Air Quality Index. It measures how pure or polluted the surrounding air is. If the numeric value on the scale is between 0-50, the quality of the surrounding air is considered healthy and satisfactory. As the values increase, the quality of the air decreases. If AQI is showing a value of 500, that means you are standing in a hazardous surrounding. Have a look at the AQI chart below for more details.

Major Causes Of Air Pollution

It is well known to everyone how air pollution happens. It happens in many ways. Sometimes careless and reckless human activities lead to the major reasons for air pollution. Even though, here are some of the common causes of air pollution.

Burning of Plastic Wastes.

How do we avoid plastics from our houses? Either we throw them or light them up, right? These careless acts will lead to the worst pollution ever. Burning them releases toxic gases like dioxins, furans, mercury, and polychlorinated. These gases are a threat to the atmosphere, vegetation, humans, and animal health. If we throw them out, they can remain in the soil for 20-500 years before fully decomposing based on the material and structure. Over these years, it pollutes the soil and harms the earth. 

So, burning and throwing plastic does not work and leads to air pollution or soil pollution in the long term perspective. Then what will we do? Well, we can recycle and reuse plastic to an extent. But once the plastic is melted and reformed into new products, the quality of plastic gets reduced. In addition, the quality of plastic will keep reducing with every successive recycling. Furthermore, recycling is limited to a number 3 or 4 times because of the quality compromise of plastic. 

In fact, we only have a limited number of opportunities in the case of plastic. Either we reduce the use of plastic or recycle and reuse them as much as we can. 

Limiting the use of plastic seems more practical and smooth in our day-to-day life. There are many instances where we can reduce the use of plastic. Here are some of the tracts where we can instantly act to limit the usages of plastic

• Use cloth bags instead of plastics bags while going to the shops.
• Use paper plates and tumblers instead of plastic ones when you arrange a tea party or get-togethers. 
• Use paper straws in restaurants and coffee shops.
• Use paper bottled soft drinks.

There are more and more situations where we can reduce the unnecessary use of plastic covers and materials. It can turn out well when more people come forward with the same mindset of bringing down plastic use. 

Are there any alternatives for plastic?

Yes, there are. But literally, there are no materials with the exact matching properties with plastic. For instance, properties like durability, strength, water-resistant, lightweight, and inexpensive are rare to find in materials without polymer as an ingredient. Scientists and researchers are trying to formulate materials with the matching properties as plastic but with less pollution.

As said earlier, there are many instances where we can reduce the use of plastic and always try to avoid it as much as we can. Even if they are baby steps towards reducing plastic, take it and help our environment. Moreover, be a part of keeping the city and your premises clean.

Industrial Emission

Industries play a colossal role in all kinds of pollutions. They contribute almost one-third to the overall when we compare industrial pollution with other causes. Industries will be the 2nd largest cause of air pollution, water pollution, and sound pollution. Pollutants like carbon monoxide, Nitrogen dioxide, and Sulfur dioxide are released when they operate factories and industries. The volume of pollutants released into the atmosphere is way more than we imagine and the problems they can make are huge.

It is necessary to know where the pollution happens and who pollutes the air the most. Studies say that industries that produce electricity pollute the atmosphere more than any other industry.

A considerable amount of pollutants is kicked from the industries when the continuous burning of fossil fuels happened. These emitted gases make the most of the troubles to the ozone layer and cause ozone layer depletion. We need both electricity and the earth. We can not avoid one or the other for any reason. The only way is to protect both without harming each other. The only solution for this will be the rise of green energy. Only the challenge facing is the continuous supply of energy. Green energy like solar and wind are very cost-effective and pollution-free when comparing to the traditional ones.

Each and every individual can contribute and can be a part of saving the earth from air pollution and global warming. Switch to green energy as much as we can and reduce the consumption of traditional electricity from the government or private companies. Nowadays, everybody has inverters in the home as a standard facility. It will not cost you much to connect 2 or 3 solar panels to the battery and save 60% power usage from the traditional electric supply.

How can we reduce industrial air pollution?

As we said earlier, industries and factories are essential for the growth of the people and nation. We can’t stop factories in the name of air pollution. What we can do is, we can find some ways to reduce the amount of air pollution. For instance, we should try to convert these harmful gases to regular gases with the help of proper techniques and setups.

Most importantly, people living near industrial areas are very likely to have many allergies and lung diseases. Always wear a mask when you are going out or going near industrial and factory areas. If you are working in an industrial area, always wear a mask and other safety gear to ensure maximum safety.

Wildfires can take place at any time. It is an unplanned and uncontrolled fire caused by lightning strikes. As the name says, it occurs largely in forest areas. Mostly, the lighting strikes on the trees, branches, dry grass, and then the fire is generated. Eventually, this fire will spread to other trees, branches, and grasses and becomes wildfires, and causes air pollution.

Wildfires are common forested areas of the United States and Canada. It is one of the causes of air pollution, deforestation, and animal extinction. In a wildfire, many animals lose their lives and shelter. Some get burns and wounds in the running through the wildfire. 

All these will continue until fire settles down. Sometimes it takes 2-3 days to settle down completely. But in the end, we lose animals, trees, the environment, and what not?

Also, sometimes the causes of wildfire can be different. Sometimes it happens due to the carelessness of people living around the forest. For instance, even trash burning and campfires can spread fire if not concerned well. So it is always recommended to take precautions while doing wildfire potential activities.

Wildfires get worse when unattended. If you notice any fires or burns that need attention, call the authorities. Sometimes the fire can be controlled before getting worse.

Transportation

Transportation holds a neck-to-neck position with industries in the rate of air pollution. As we all know, the number of vehicles on the road is increasing day by day. Just look around, we could see houses with more than three vehicles even if they don’t need all of them. As the number of vehicles increases, the rate of pollution also tends to be increased. Old model vehicles are more likely to produce more pollution than new ones. Because when the vehicles get older and older, the amount of carbon emission increases. The rate of pollution is still on the rise even after the government and authorities made pollution laws strict. 

Every country has its own vehicle emission standards or norms for the safety of the environment and people living in the country. But still, transportation holds the position for the majority of air pollutions happening around the world.

How can we reduce pollution caused by vehicles?

Earlier, it was challenging to find an alternative for fuels like petrol or diesel. Right now, technology has improved – researchers found a better alternative solution for the petrol and diesel engines for automobiles. Yes, they are EV’s. Electric vehicles are completely different from traditional vehicles. They are pollution-free and highly efficient than fuel engines. Electric vehicles can be charged from the house or charging stations in and around the city. EV’s have 5x efficiency more than the regular diesel or petrol-fueled automobiles and 4x lesser reduced pollution.

EV’s are on the rise. By 2025, at least 50% of the new vehicles coming out from the factories will be electric vehicles. It will seriously help to reduce the rate of pollution to some extend. People will switch to EV’s when companies launch better models with luxury and comfort.

It may sound crazy to most of us. But think about walking a little every day and avoid taking cars or bikes for smaller distances. Or, use a bicycle to travel nearby. It will help us to improve both our health and the earth’s health.

What are the health issues due to air pollution?

The quality of the air we breathe is very crucial. Poor quality can cause many health diseases in both adults and kids. Especially to the people living in cities, the chances of getting a disease like heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung cancer, and acute lower respiratory infections are very high.

Long-term exposure to polluted air in kids can lead to loss of lung capacity, asthma and emphysema. In addition, senior citizens are more likely to get allergies and breathing difficulties since they are less immune to the conditions. As a precaution to all of these, we can wear a mask while going out and traveling. If you are living in a highly polluted area, consider buying an air purifier for your home. An air purifier can help to improve the quality of air by filtering and thereby enabling a healthy environment inside our home for everyone.

How does air pollution affect environmental health?

The toxic gases also affect the environment in the same way. As the amount of harmful gases increases in the earth, the uncertainty of the environment’s health also increases. Changes in climates like temperature hikes, monsoon pattern shifts, and unexpected cyclones are a few examples. In these, ozone layer depletion is being the most complicated one.

We already know what is an ozone layer, and whats does it do? Let’s recall them for a while. The ozone layer is a part of the earth’s atmosphere, and it absorbs almost all of the sun’s harmful ultraviolet light. Guess what will happen when the ozone layer gets holes. All the harmful rays will fall into the animals, plants, and people on earth through the ozone layer holes. Studies say that by 2064 the ozone layer concentration levels may come to zero if the rate of pollution continues invariably. If that happens, the earth will not be a suitable place to live. The fun factor is, we don’t have any space other than earth to live right now. So, we have to protect the planet from being a desert.

Day by day, the rate of pollution is increasing. The hard truth is, nobody is really caring about the future of our planet. Even the government and authorities are keeping their eyes closed on social issues like global warming, air pollution, and soil erosion. If it keeps going like this, the earth will become uninhabitable.

Protecting the earth from pollutions is not deputed on somebody else. Each one of us should take responsibility and behave sensibly to protect the earth from pollution.

Air Pollution Control

Air pollution & its control, air pollution definition.

“Air Pollution is the release of pollutants such as gases, particles, biological molecules, etc. into the air that is harmful to human health and the environment.”

Air Pollution Diagram

Table of Contents

What is Air Pollution?

Types of air pollutants, primary pollutants, secondary pollutants, causes of air pollution.

Air pollution refers to any physical, chemical or biological change in the air. It is the contamination of air by harmful gases, dust and smoke which affects plants, animals and humans drastically.

There is a certain percentage of gases present in the atmosphere. An increase or decrease in the composition of these gases is harmful to survival. This imbalance in the gaseous composition has resulted in an increase in earth’s temperature, which is known as global warming.

There are two types of air pollutants:

The pollutants that directly cause air pollution are known as primary pollutants. Sulphur-dioxide emitted from factories is a primary pollutant.

The pollutants formed by the intermingling and reaction of primary pollutants are known as secondary pollutants. Smog, formed by the intermingling of smoke and fog, is a secondary pollutant.

Also Read:  Water Pollution

Following are the important causes of air pollution:

Burning of Fossil Fuels

The combustion of fossil fuels emits a large amount of sulphur dioxide. Carbon monoxide released by incomplete combustion of fossil fuels also results in air pollution.

Automobiles

The gases emitted from vehicles such as jeeps, trucks, cars, buses, etc. pollute the environment. These are the major sources of greenhouse gases and also result in diseases among individuals.

Agricultural Activities

Ammonia is one of the most hazardous gases emitted during agricultural activities. The insecticides, pesticides and fertilisers emit harmful chemicals in the atmosphere and contaminate it.

Factories and Industries

Factories and industries are the main source of carbon monoxide, organic compounds, hydrocarbons and chemicals. These are released into the air, degrading its quality.

Mining Activities

In the mining process, the minerals below the earth are extracted using large pieces of equipment. The dust and chemicals released during the process not only pollute the air, but also deteriorate the health of the workers and people living in the nearby areas.

Domestic Sources

The household cleaning products and paints contain toxic chemicals that are released in the air. The smell from the newly painted walls is the smell of the chemicals present in the paints. It not only pollutes the air but also affects breathing.

Effects of Air Pollution

The hazardous effects of air pollution on the environment include:

Air pollution has resulted in several respiratory disorders and heart diseases among humans. The cases of lung cancer have increased in the last few decades. Children living near polluted areas are more prone to pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution.

Global Warming

Due to the emission of greenhouse gases, there is an imbalance in the gaseous composition of the air. This has led to an increase in the temperature of the earth. This increase in earth’s temperature is known as global warming . This has resulted in the melting of glaciers and an increase in sea levels. Many areas are submerged underwater.

The burning of fossil fuels releases harmful gases such as nitrogen oxides and sulphur oxides in the air. The water droplets combine with these pollutants, become acidic and fall as acid rain which damages human, animal and plant life.

Ozone Layer Depletion

The release of chlorofluorocarbons, halons, and hydrochlorofluorocarbons in the atmosphere is the major cause of depletion of the ozone layer. The depleting ozone layer does not prevent the harmful ultraviolet rays coming from the sun and causes skin diseases and eye problems among individuals. Also Read:  Ozone Layer Depletion

Effect on Animals

The air pollutants suspend in the water bodies and affect aquatic life. Pollution also compels the animals to leave their habitat and shift to a new place. This renders them stray and has also led to the extinction of a large number of animal species.

Following are the measures one should adopt, to control air pollution:

Avoid Using Vehicles

People should avoid using vehicles for shorter distances. Rather, they should prefer public modes of transport to travel from one place to another. This not only prevents pollution, but also conserves energy.

Energy Conservation

A large number of fossil fuels are burnt to generate electricity. Therefore, do not forget to switch off the electrical appliances when not in use. Thus, you can save the environment at the individual level. Use of energy-efficient devices such as CFLs also controls pollution to a greater level.

Use of Clean Energy Resources

The use of solar, wind and geothermal energies reduce air pollution at a larger level. Various countries, including India, have implemented the use of these resources as a step towards a cleaner environment.

Other air pollution control measures include:

• By minimising and reducing the use of fire and fire products.
• Since industrial emissions are one of the major causes of air pollution, the pollutants can be controlled or treated at the source itself to reduce its effects. For example, if the reactions of a certain raw material yield a pollutant, then the raw materials can be substituted with other less polluting materials.
• Fuel substitution is another way of controlling air pollution. In many parts of India, petrol and diesel are being replaced by CNG – Compressed Natural Gas fueled vehicles. These are mostly adopted by vehicles that aren’t fully operating with ideal emission engines.
• Although there are many practices in India, which focus on repairing the quality of air, most of them are either forgotten or not being enforced properly. There are still a lot of vehicles on roads which haven’t been tested for vehicle emissions.
• Another way of controlling air pollution caused by industries is to modify and maintain existing pieces of equipment so that the emission of pollutants is minimised.
• Sometimes controlling pollutants at the source is not possible. In that case, we can have process control equipment to control the pollution.
• A very effective way of controlling air pollution is by diluting the air pollutants.
• The last and the best way of reducing the ill effects of air pollution is tree plantation. Plants and trees reduce a large number of pollutants in the air. Ideally, planting trees in areas of high pollution levels will be extremely effective.

Educational Resources Related to Air Sensor Technology

Air sensor technologies are increasingly being used by a variety of audiences and offer opportunities for educational enrichment. EPA developed several presentations that provide background information on air quality, air pollution sources, and air sensors. Additionally, EPA and collaborators developed educational activities and curriculum which are available to the public. These resources may be used in group settings such as classrooms or community workshops, in other educational settings, or by individuals exploring on their own. These materials may also be adaptable for a variety of age groups from elementary school students to adults.

• Introductory Presentation on Air Quality and Air Sensors
• Air Sensor Loan Programs - Air Quality Lesson Plans

Using Vegetative Barriers to Improve Air Quality – Activities and Lessons for K-5 Educators

Build your own particle sensor kit, airmapper and retigo lesson plans, science to achieve results (star) grant funded resources, introductory presentations on air quality and air sensors.

To help facilitate the use of air sensors, EPA developed several presentations that overview general and more technical information on air quality, air pollution, and air sensors. The presentations include:

• Air Quality 101: A Background on Air Pollution Presentation Slides  –  covers several topics including the history of air pollution and regulation in the US, common air pollutants and their sources, the health and environmental effects of air pollution, how air pollutants are measured in the US, and where air quality data can be found.
• Advanced Topics in Using Sensors to Measure Air Quality Presentation Slides  –  covers the difference between air sensors and regulatory monitors, interpreting air sensor evaluations, and sensor collocation, siting, quality control, and data analysis.

Air Sensor Loan Programs – Air Quality Lesson Plans

Between 2019 and 2021, EPA launched pilot air sensor loan programs with several local partners associated with public libraries, public museums, and tribal communities. To support those programs and to encourage the use of air sensor technology for air quality education, a series of educational resources were developed.

These resources include hands-on lesson plans for classroom, group, or individual instruction. The lesson plans are written for the AirBeam2 or PurpleAir sensors but are adaptable for use with any handheld particulate matter (PM) sensor or stationary PM sensor with a crowdsourced map, respectively. The available lesson plans include:

• What is in the Outdoor Air? Exploring Particulate Matter (PM) Sources and Air Quality Outdoors
• Hidden Particulate Matter Indoors! Explore Your Environment
• My Pollution Bubble! Exploring My Personal Particulate Matter (PM) Exposure
• The Power of Plants! How Vegetation Can Help Protect Us from Air Pollution
• Is That Smoke Affecting Me? ​Using Crowdsourced Public Data to Explore Air Quality During Smoke Events

Each lesson plan includes:

• Instructor guide that includes discussion points and answers to the questions posed to the participants
• Participant guide which includes a worksheet for observations and discussion question responses
• Slides introducing the topic and activity
• Summary of how the lesson aligns with Next Generation Science Standards (NGSS)
• Resource guide to connect users to additional information and activities
• Frequently asked questions document to answer common inquires

In addition to the introductory presentation mentioned in the section above, the following resources may also provide support for these lesson plans:

• AirBeam2 Quick Start Guide and Presentation Slides
• AirBeam2 Instructional Video ( approximately 13 minutes long )
• PurpleAir Quick Start Guide and Presentation Slides (coming soon)

For questions or more information, please contact Andrea Clements ( [email protected] ) and Rachelle Duvall  ( [email protected] ).

Vegetative barriers, which include trees and bushes, can help reduce pollution near busy highways and roads. EPA has been researching how vegetative barriers can improve air quality. Researchers developed custom-built air sensors that can be used to measure air quality to see the effects of vegetative barriers over time. As part of this research, K-5 lesson plans and activities have been developed that focus on air quality, air sensors, air pollution, and the impact of air pollution on human health. Although written with the custom-built air sensor in mind, these lessons are adaptable to other types of air sensors.

For questions, contact Rebecca Dodder ( [email protected] ).

Particle pollution, known as particulate matter (PM), is one of the major air pollutants regulated by EPA to protect public health and the environment. A PM air sensor kit was developed by EPA researchers as an educational tool to teach the public about air quality and air science. This activity can be completed in under an hour and gives hands-on experience with electronics and coding, but it is not intended to be used as a long-term air monitoring device. This resource provides instructions on buying the parts for the kit, step-by-step instructions for assembly, and a lesson plan. 

• Build your own particle sensor information

The AirMapper is a custom-built portable air monitoring device that was developed by EPA. The device measures fine particulate matter (PM 2.5 ), carbon dioxide (CO 2 ), and other parameters, including temperature, humidity, and noise. Data collected on the AirMapper can be downloaded and viewed using the RETIGO web-platform. Six lesson plans and five classroom activities were developed based on the AirMapper and RETIGO. These resources are designed for 3 rd to 8 th grades.

Additionally, a manual for the AirMapper has been developed for anyone who wants to build this device. The manual includes instructions on buying the parts for the device, assembly, operation, and troubleshooting.

• AirMapper Design, Operation and Maintenance Report  
• Real Time Geospatial Data Viewer (RETIGO)

To obtain the lesson plans, contact Rachelle Duvall ( [email protected] )

University of Washington - Air Pollution Monitoring for Communities

This curriculum was used by university researchers in an after-school program with high school students mentored by undergraduate students. The program focused on preparing students to conduct their own research on particulate matter using low-cost sensors.

UAE does not plan to re-open F-35 fighter jet talks with US

The United Arab Emirates does not expect to resume talks with the U.S. about a multi-billion dollar deal for F-35 warplanes, irrespective of who is elected to the White House in November, a senior UAE government official said on Saturday.

White House news photographers accuse Harris of 'reduction in access,' Axios reports

by JACKSON WALKER | The National Desk

WASHINGTON (TND) — The White House News Photographers Association sent a letter last month to Vice President Kamala Harris’s campaign condemning what it called an “unprecedented reduction in access," according to Axios .

Jessica Koscielniak, president of the WHNPA, reportedly expressed outrage that "the four independent news photographer seats have been downgraded to one” aboard Air Force Two. The group had reportedly been told White House officials were weighing a “chaser plane” to transport press behind the vice president.

"The current situation puts the still photographers at a distinct disadvantage on every trip,” White House news photographer Doug Mills told Axios. "It's essential to us for people to understand the importance of having a full photographer pool. Every photographer sees each event differently.”

Neither Harris’s campaign nor the White House responded to a request for comment from The National Desk (TND). However, Harris's office told WHNPA following the letter it learned both adding a chase plane and more seats on Air Force Two "are not viable given available resources, including personnel and aircraft," according to Axios.

Some have accused Harris of avoiding the media during her campaign. However, U.S. Commerce Secretary Gina Raimondo on Monday told CNBC it is challenging for Harris to allocate time for media interviews due to her “punishing schedule.”

“This is a presidential election like no other,” Raimondo said. “[Harris] only has a few weeks to do everything, and she’s spending her time talking to Americans. She has a punishing schedule out and about, everywhere, being with the people who she wants to elect her."
