Air pollution

The composition of materials in the atmosphere can alter due to natural and man-made activities. Chemicals, particulates, and biological matter can cause health problems for organisms
and environmental harm for the land.

Primary pollutants are emitted directly
e.g. from naturally occurring events such as volcanic ash, dust storms, forest fires, or man-made activities such as sulphur dioxide from industries; CO2 from vehicle exhausts.
