One could claim that Air Pollution started when humans
began burning fuels or open-burning. In other words, all man made emissions into the air can be called air pollution, because they alter the chemical composition of the natural atmosphere.

Pollutants emitted directly into the air. Primary pollutants are usually produced from a process.
Sulphur oxides (SOx) Carbon monoxide (CO) Nitrogen oxides (NOx) Ammonia (NH3)

A chemical compound with the formula SO2 . Coal and petroleum often contain sulphur compounds, and theircombustion generates sulphur dioxide.
