The fossil fuels like coal and petroleum contain small amounts of nitrogen and sulphur. When fossil fuels are burnt, it produces oxides of nitrogen and sulphur. These gases cause inhalation problems and in presence of rain forms acid rain. Burning of fossil fuels also increase the amount of suspended particles in air that reduce the visibility.

Coa l and petroleum are the fossil fuels. They are burnt to get energy. Combustion of fossil fuels produces (i) suspended particles (ii) sulphur oxides, (iii) nitrogen oxides, (iv) carbon dioxide, (v) carbon monoxide, (vi) vapour of hydrocarbons. All these are air pollutants. Hydrocarbos acts as a source of cancer. Along with nitrogen oxides, they produce ozone and smong. Sulphur and nitrogen oxides give rise to acid rain. They are also irritatants and damage eyes and nasal tract.
