Air Pollution

What is air pollution?

Air pollution is a problem which has been plaguing the Earth for decades. This is an issue which is a danger to the planet. The pollution in the air is caused by a variety of things. The fuel you use for an internal combustion engine is one of them. The other is the burning of coal and the production of chemicals. The issue is that these emissions are not only harming the environment. It is also harming the people.

There are many ways to combat this issue. One way is to reduce the amount of air pollution generated. Another is to find new ways of generating electricity. This is a difficult solution as we still need to power our cars, but it is a viable one. A final solution is to increase the capacity of the air filter. This is one of the easier solutions as it is quite easy to do.

Air Pollution

Air pollution facts.

  1. According to the American Lung Association,
    “Excessive exposure to air pollution is linked to nearly 60,000 premature deaths every year in the United States.”
  2. Nearly half of all Americans live in counties that do not meet air quality standards set by the EPA.
  3. A new study found that air pollution can cause sudden death in people who have pre-existing heart problems.
  4. In 2012, air pollution was linked to the early deaths of 1.7 million people in China.
  5. If the European Union continues to violate air pollution standards, it will face fines of $330 million per year.

What Causes Air Pollution?

Air pollution is the release of chemicals and particulates into the air that can eventually harm human health and the environment. Air pollution can come from natural sources, such as wildfires, or from human-made sources such as factories, vehicles, and power plants.

Air pollution can be classified into two types: primary and secondary.

Primary air pollutants are those that are emitted directly into the air, such as nitrogen and sulfur oxides, volatile organic compounds, and carbon monoxide. These pollutants are usually released directly into the air by the industries, power plants, vehicles, and other man-made sources that produce them.

Secondary air pollutants are those that form in the air when primary pollutants react with each other. For example, nitrogen oxide reacts with hydrocarbons in the presence of sunlight to form ground-level ozone (smog).

  • Air pollution can affect human health in several ways, including:
  • Coughing, wheezing, shortness of breath, and asthma attacks in people with asthma
  • Increased risk of heart attacks and premature death in people with cardiovascular disease
  • Aggravation of existing respiratory and cardiovascular disease
  • Aggravation of existing lung disease, such as bronchitis and emphysema
  • Development of lung disease, such as bronchitis, in otherwise healthy people
  • Damage to plants and trees

Causes of Air Pollution

There are many causes of air pollution. In many cases, several causes are linked together. For example, vehicle emissions are the leading cause of air pollution in the United States. In addition, transportation is responsible for 75 percent of U.S. oil consumption, and oil consumption is the leading cause of global warming.

Some of the most common include:


Combustion is the process of burning fuel. Combustion releases pollutants into the air.

When fuel is burned, it releases gases into the air, including carbon dioxide, carbon monoxide, nitrogen oxides, sulfur oxides, and hydrocarbons.


Petroleum is the material extracted from crude oil. It is used to make fuels and chemicals.

Petroleum is burned to power vehicles, generate electricity, and heat buildings.

Industrial Activities

Industrial activities such as mining, manufacturing, and processing can release pollutants into the air.

Mining Coal is an important source of energy in the United States. It is burned to generate electricity and to heat buildings. Mining coal releases pollutants into the air. Iron and steel industries also release pollutants. Manufacturing Industries release many different kinds of pollutants. Some of the most common are: Chemicals released into the air by chemical plants during the manufacturing process.

Waste products released from manufacturing facilities

Particulates released into the air by factories that make concrete, paper and wood products, and other non-metallic products.

Smoke and gases released from manufacturing facilities that produce metal products.

Emissions from factories that produce glass and chemicals.

Fuel used in factories and other industrial facilities.

Some industrial pollutants can also be released directly into water. For example, animal waste from factory-farmed animals is sometimes released directly into rivers.

Fossil Fuels

Fossil fuels are a primary source of energy in the United States and around the world. They are burned to generate electricity, produce heat, and drive vehicles.

Fossil fuels include coal, oil, and natural gas. They are formed when dead animals and plants are buried in sediment and undergo chemical changes.

Burning fossil fuels releases pollutants into the air. Some of the most common are:

  • Carbon dioxide, a greenhouse gas.
  • Particulate matter, tiny particles that can aggravate respiratory diseases.
  • Sulfur dioxide, which can induce asthma symptoms and cause acid rain.
  • Nitrogen oxides, which can cause smog and aggravate respiratory diseases.
  • Volatile Organic Compounds, which are responsible for the creation of smog.
  • Volatile organic compounds are chemical compounds that easily change from gas to liquid or solid. They are released into the air during the burning of fossil fuels, and are also released into water and soil during the manufacturing of pesticides, herbicides, and other chemicals.

Pesticides and herbicides

Pesticides are chemicals used to kill pests, such as insects and weeds.

Herbicides are chemicals used to kill weeds.

Pesticides and herbicides are used on crops, lawns, and gardens. They are also used on farms and in forests to kill insects and weeds.

Pesticides and herbicides are often made from petroleum. Sometimes, they are made from naturally occurring organic compounds, like arsenic and lead.

Pesticides and herbicides can also create secondary air pollutants. For example, sulfates are formed when sulfur is used as a pesticide. Sulfates are a primary component of acid rain.

Effects of Air Pollution


Smog can cause a variety of health problems. Smog irritates eyes and lungs. It can cause asthma attacks and bronchitis, and aggravate existing respiratory and cardiovascular disorders such as emphysema and heart disease.

Children are especially susceptible to the effects of smog. The elderly and people with respiratory ailments are also at greater risk from smog.


The first step in solving smog problems is understanding what causes smog. The next step is to determine what can be done to prevent or reduce smog.

Toxic emissions from cars and trucks are a major cause of smog. To reduce smog, you should:

  • Limit the use of your car
  • If possible, work at home on days when air pollution is high
  • Keep the car tuned up to reduce emissions
  • Avoid driving when the air quality is bad
  • In the home, an air conditioner can help reduce smog. However, air conditioning can also add to smog problems by increasing the load on the power plant and increasing energy consumption. You can save energy by keeping your house cool without air conditioning.
  • Smog can also be reduced by recycling. Recycling paper, glass, metal, and plastic materials saves energy and limits the amount of waste that must be incinerated or buried.

Finally, the best way to fight smog is to reduce its major sources. Some sources can be reduced by individuals. For example, you can help reduce smog by:

  • Turning off lights when you leave a room
  • Avoiding the use of solvents and pesticides
  • Carpooling
  • Using a broom instead of a vacuum cleaner
  • Insulating your home
  • Using low-energy light bulbs

Other sources of smog cannot be reduced by individuals. The federal government has established standards and regulations for most major sources of smog. These sources include factories, chemical plants, vehicle emissions, and trash incinerators.

The Effects of Smoking

Smoking tobacco products is the most important preventable cause of death in the U.S. Smoking is responsible for about 3 out of every 10 deaths, or an estimated 300,000 deaths each year.

Tobacco smoke contains more than 4,000 chemicals, many of which are harmful. These chemicals include carbon monoxide, ammonia, hydrogen cyanide, and formaldehyde. Some of these can cause cancer, and most can damage the lungs.

Acid rain

What are the effects of Acid Rain?

  1. Acidification.
  2. Transforms soil and freshwater.
  3. Damages and kills trees.
  4. Damages and kills crops.
  5. Damages and kills buildings.

Acid rain can cause the acid content of soil to increase, which decreases the amount of minerals that plants can absorb. Acidic rain can also cause metal and concrete to corrode, and it can also cause respiratory problems in humans.

How can the effects of acid rains be prevented?

Acid rains can be prevented by reducing the amount of sulphur and nitrogen compounds that are released into the air. These compounds can be released by burning coal, oil, and gas, and by certain manufacturing processes.

Water pollution

What is a negative effect of water pollution?

The negative effects of water pollution are many, and they range from the general to the specific. The specific effects of water pollution are a bit more difficult to enumerate, but general effects of water pollution include the death of aquatic life, the spread of diseases and infections, and the decrease of the population of organisms living in the area.

A decrease in the population of organisms living in the area is one of the most specific effects of water pollution. Even if aquatic life can survive in the area, the population of those organisms can decrease as a result of water pollution. This is because the negative effects of water pollution are not limited to the organisms that live in the water. Instead, water pollution spreads and affects other organisms, including the organisms that live on land.

How air pollution causes water pollution?

The relationship between air pollution and water pollution is a bit complicated. Air pollution can cause water pollution, but water pollution can also cause air pollution. The two types of pollution are related in a variety of ways, and understanding that relationship is important for understanding how to prevent air pollution and water pollution.

Air pollution can cause water pollution because the pollutants in the air eventually fall to the ground. When the pollutants fall to the ground, they enter the aquifers and the rivers. Air pollution can also cause water pollution because rain can be polluted with air pollutants.

Greenhouse gases

The CO2 emissions in the atmosphere are an important factor in climate change. The CO2 emissions have increased by more than 40% since the beginning of the Industrial Revolution, from 280 ppm (parts per million) in 1750 to 400 ppm in 2005.

Most of the CO2 emissions come from fossil fuel combustion, such as the burning of coal, oil and natural gas.

The burning of fossil fuels liberates CO2, which was captured by plants and soil over millions of years.

The CO2 emission from fossil fuels is also responsible for other air pollutants, like SO2 and NOx. These air pollutants cause acid rain and ground-level ozone (smog) and contribute to the formation of fine particulate matter (PM2.5) in the air.

How air pollution causes greenhouse gases?

In addition to CO2, burning fossil fuels also releases other greenhouse gases, such as methane, N2O and HFCs.

Emissions from agriculture, such as methane from rice paddies and CO2 from animal husbandry, are also important.

These greenhouse gases cause the greenhouse effect that causes global warming.

Aerosols (solid or liquid particles suspended in the atmosphere) have direct and indirect effects on climate change. The aerosols can have a cooling effect by reflecting light. The direct effect of aerosols on climate change is more important.

Particulate matter (PM) or fine particulate matter (PM2.5) can cause health problems, such as respiratory diseases, bronchitis and other diseases.

A study from 2013 found that the PM2.5 in the air killed some 670,000 people in China in 2010, accounting for 17.8% of all deaths in China.

China has made great efforts in improving air quality in recent years and the number of deaths from PM2.5 has dropped to about 50,000.

The link between air pollution and climate change is complex and interwoven. The major air pollutants that cause climate change are CO2, CH4 and N2O, which are also greenhouse gases.

Other air pollutants can cause CO2 to be released from the land, such as the release of CO2 through the degradation of peatlands in Indonesia. The air pollutants, especially fine particulate matter, also cause the formation of secondary organic aerosols (SOA) in the atmosphere. The SOA can enhance the formation of cloud droplets and make clouds more reflective. The SOA can also absorb sunlight. The effects of SOA on climate change play a significant role in climate change.

The combination of all these effects results in more climate change.

What is the Air Quality Index (AQI)?

The Air Quality Index is a scale that measures the concentration of pollutants in the air. It goes from 0 to 500, with the higher numbers indicating the worse the quality. Zero, for example, means that there aren’t any pollutants in the air.

Why is today’s AQI higher than yesterday’s?

If the AQI is higher than yesterday, it doesn’t necessarily mean that the air quality is getting worse. It could be that the weather conditions are different today than they were yesterday.

For example, a higher AQI can be caused by windy conditions, which can push pollutants around and spread them into different areas.

How is the AQI calculated?

The Air Quality Index is calculated by averaging the level of five of the most common pollutants, including ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.

Why are some pollutants measured and others not?

For the AQI, only the five pollutants listed above are measured because they are the ones most likely to affect human health.

The Air Quality Index does not include other pollutants such as carbon dioxide, nitrogen, and water vapor, because they are not likely to affect human health.

What is the health impact of different levels of the AQI?

The AQI is divided into six categories—excellent, good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy—according to health impact. However, different countries use different definitions.

For example, China’s AQI includes seven categories, and India’s AQI includes eight categories. In China, the air quality is divided into three categories: good, semi-good, and bad. In India, there are four categories: very good, good, moderate, and poor.

What are the health risks associated with different levels of the AQI?

The EPA defines the effects of different levels of the AQI according to health impact:

  1. Levels of the AQI below 50 indicate good air quality. At these levels, people may see, smell, or taste pollutants but they are unlikely to have any adverse health effects.
  2. At levels from 50 to 100, air quality is deemed to be acceptable. At these levels, people are unlikely to experience health effects. However, people with heart or lung disease, older adults, and children are more sensitive to air pollution.
  3. At levels from 101 to 150, the air quality is considered to be moderate. In the short term, people may experience health effects if they are active outdoors. In the long term, the EPA states that people who are active outdoors are at a greater risk of developing lung diseases, like asthma, or heart disease.
  4. At levels from 151 to 200, the air quality is considered to be unhealthy for sensitive groups. At these levels, people with heart or lung disease, older adults, and children are at an even greater risk of developing lung diseases, like asthma, or heart disease.
  5. At levels above 200, the air quality is considered to be unhealthy. At these levels, everyone is at risk of experiencing health effects.
  6. At levels above 300, the air quality is considered to be very unhealthy. At these levels, everyone is at risk of experiencing more serious health effects.
  7. At levels above 500, the air quality is considered to be hazardous. At these levels, everyone is at risk of experiencing serious health effects.

What are the health risks associated with air pollution?

Many people are exposed to air pollution levels that are considered unhealthy. The EPA states that exposure to air pollution can cause a number of adverse health effects, including:

  • Migraines and mood disorders
  • Reduced lung function
  • Cardiovascular disease
  • Asthma
  • Respiratory symptoms

The EPA also states that there is evidence linking exposure to air pollution to cancer, but more research is needed to confirm this.

How can I reduce my exposure to air pollution?

The EPA recommends following these steps to reduce your exposure to air pollution:

  • Minimize your exposure: If you can’t avoid being outside, stay in the shade, wear a face mask, and limit your exercise.
  • If you can’t avoid being outside, stay in the shade, wear a face mask, and limit your exercise. Avoid the peaks: Avoid being outside when air pollution levels are highest. The best times to avoid outside activities are between 11 a.m. and 4 p.m.
  • Avoid being outside when air pollution levels are highest. The best times to avoid outside activities are between 11 a.m. and 4 p.m. Know your AQI: Check the AQI before going outside so you know what your level of exposure is.
  • Check the AQI before going outside so you know what your level of exposure is. Reduce your time outdoors: If your AQI is unhealthy, limit your time outdoors.

How to Help Reduce Air Pollution?

Some ways to reduce air pollution include the following:

  • Create a clean air act that bans the use of the worst air polluting substances, which are many types of plastics
  • Create the “Keep Your Country Beautiful”-like campaign to get people to recycle and buy products that are less polluting
  • Create public transportation so people have less of a need to drive and rely on vehicles that pollute the air. I.e. increase the number of people who use public transportation, such as trains and buses
  • Create more trees and plant grass to help reduce air pollution
  • Create more and better recycling programs
  • Require factories and companies to use less polluting fuels
  • Require that factories and companies use more clean technology
