various chemicals that causes air pollution
Answers
Various chemicals (pollutants) that causes air pollution are:-
Main air pollutants are:
Sulphur oxides (SOx) – Mainly Sulphur dioxide (SO2). It is one of the causes for concern over the environmental impact of the use of fuels as power sources.
Nitrogen oxides (NOx) - NO2 is one of the most prominent air pollutants. Nitrogen (N) compounds, emitted as NOX and NH3, are now the principal acidifying components in our air and cause eutrophication of ecosystems.
Particulate matter - Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols.
Ozone (O3) - Ozone is not directly emitted into the atmosphere but formed from a chain of photochemical reactions following emissions of precursor gases: nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOC).
Carbon monoxide (CO) - It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide.
Carbon dioxide (CO2) - emitted from sources such as combustion, cement production, and respiration.
Heavy metals, such as arsenic (As), cadmium (Cd), lead (Pb) and nickel (Ni)
Benzene and benzo(a)pyrene
Ammonia (NH3) - emitted from agricultural processes.

and various aerosols.
GHG like CO2 , NO2 , NO3 , oxides of sulphur , etc.
