AIr Pollution in India

Abstract Air pollution is an increasingly important environmental issue in urban areas. The rapid growth of motor vehicles along with the industrial development contributes to a definite air pollution pattern with clear trends of deteriorated air quality. Air pollution is basically the presence of foreign substances in the Air. "Air pollution is the excessive concentration of foreign matter in the air which adversely affects the well-being of the individual or causes damage to the property (American, Medical Association). Air pollution is not a recent phenomenon: King Edward I of England tried to clear the smoky sky over London in 1272by banning the use of coal. The British Parliament ordered the torturing and hanging of man who sold and burned the outward coal. Under Richard II (1377-1399) and later under Henry V (1413~1422), England took steps to regulate and restrict the use of coal. Such natural processes as forest fires, decaying vegetation, dust storms and volcanic eruptions have always contaminated the air. Although the total global production of many gases and particulate matter recognized as pollutants is much greater from natural resources than from man-made sources, but global distribution and dispersion of those natural pollutants result in low average concentrations. By precipitation, oxidation and absorption into the ocean and the soil, atmosphere can clean itself of all known pollutants if given sufficient time. On the other hand, man generated pollutants are continuously emitted and concentrated in small geographic region; hence air pollution problem is generally anthropogenic phenomena. Presently the rate of pollutants discharged into the atmosphere in highly populated regions exceeds the natural cleaning rate of atmosphere. In the present research focused on the status of Air Pollution in India. Keywords: Suspended Particles, Sulphur dioxide, Nitrogen oxides, Carbon monoxide. ozone and hydrocarbon pollutants
