What can be causes of air pollution?
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.
What activity causes the most air pollution?
The Burning of Fossil Fuels The Burning of Fossil Fuels Most of the air pollution takes place due to the burning of fossil fuels such as coal, oil, and gasoline to produce energy for electricity or transportation. The release of carbon monoxide at a high level indicates how much fossil fuel is burned.
What are 5 ways humans cause air pollution?
Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills.
What are the causes of indoor air pollution in which regions is indoor air pollution a problem?
Indoor air pollution is caused by burning solid fuel sources – such as firewood, crop waste, and dung – for cooking and heating. The burning of such fuels, particularly in poor households, results in air pollution that leads to respiratory diseases which can result in premature death.
What is air pollution causes and effects?
The main cause of air pollution is the burning of fossil fuels. Harmful gases like sulphur dioxide, carbon monoxide etc. are released into the atmosphere due to incomplete combustion of fossil fuels which pollutes the air.
What are the main causes of air pollution Class 8?
The sources of air pollutants are factories, power plants, automobile exhausts and burning of firewood and dung cakes. The Vehicles produce high levels of pollutants like carbon monoxide, carbon dioxide, nitrogen oxides and smoke.
What are the 6 types of air pollution?

What are causes and effects of air pollution?
The main cause of air pollution is the burning of fossil fuels. Harmful gases like sulphur dioxide, carbon monoxide etc. are released into the atmosphere due to incomplete combustion of fossil fuels which pollutes the air.
What causes outdoor air pollution?
The common sources of outdoor air pollution are emissions caused by combustion processes from motor vehicles, solid fuel burning and industry. Other pollution sources include smoke from bushfires, windblown dust, and biogenic emissions from vegetation (pollen and mould spores).
