Which are the 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 is the main source of pollutants in photochemical smog?
Photochemical smog is a mixture of about one hundred primary and secondary pollutants formed under the influence of sunlight. Ozone is the main pollutant.
What is air pollution and its sources?
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.
What are the main causes of air pollution in metro cities?
