The common air pollutants are:
- Particulate matter (PM10 and PM2.
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Carbon monoxide (CO)
- Sulphur dioxide (SO2)
Which gas causes the most air pollution?
Carbon dioxide (CO 2): Because of its role as a greenhouse gas it has been described as “the leading pollutant” and “the worst climate pollutant”. Carbon dioxide is a natural component of the atmosphere, essential for plant life and given off by the human respiratory system.
What are the 3 main air pollutants?
Common Air Pollutants
They are particulate matter (often referred to as particle pollution), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm human health, harm the environment, and cause property damage.
What are the 7 major air pollutants?
Major air pollutants include carbon monoxide (CO), ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), sulphur dioxide (SO2) and volatile organic compounds (VOC).

What are the 4 types of pollutants?
The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution.
What are the 2 main types of air pollution?
The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.
What are the 4 major indoor air pollutants?
They fall into one of four categories: VOCs, biological pollutants, combustion byproducts, and legacy pollutants. These pollutants can affect the health and comfort of building occupants.
What are the major types of pollutants?
Pollutants with the strongest evidence for public health concern include particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2) and sulphur dioxide (SO2). Health problems can occur as a result of both short- and long-term exposure to these various pollutants.
Which gas does not pollute air?
Most vehicles run on fuels that emit harmful gases when burnt. These gases mainly include carbon monoxide, nitrogen dioxide and sulphur dioxide. Oxygen, on the other hand, does not cause air pollution and is important for our survival.
What are main causes of air pollution?
Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.

What is the #1 cause of pollution?
The number one source of outdoor air pollution is the burning of fossil fuels, primarily by motor vehicles. However, manufacturing industries, mining, and coal- and gas-fired power stations are also responsible for polluting the atmosphere.
Who died from air pollution?
The combined effects of ambient air pollution and household air pollution is associated with 7 million premature deaths annually.
What makes air clean?
Clean, dry air consists primarily of nitrogen and oxygen—78 percent and 21 percent respectively, by volume. The remaining 1 percent is a mixture of other gases, mostly argon (0.9 percent), along with trace (very small) amounts of carbon dioxide, methane, hydrogen, helium, and more.
What is dirty air called?
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog.
