Human Activities that are leads to air pollution:-

Air Pollution by industries, which in some regions has already led to a decrease in air transparency.It results from the waste from steel mills,cement and coking plants,chemical industries,gas plants and the smelting of ferrous metals.Among these residues are toxic and irritant subtances,photochemical pollutants,dust etc.
