ENVIRONMENTAL EFFECTS OF AIR POLLUTION AND APPLICATION OF ENGINEERED METHODS TO COMBAT THE PROBLEM

摘要

Air pollution can have serious costs, penalties and consequences for the health of human beings and also ruthlessly distresses the natural bio-network and ecosystems. The main consequences of air pollution are global warming, acid rain, smog, ozone depletion etc. India ranks 13th most polluted country with an annual mean of 109 μg/m~3 of PM_(10). China contributes 21.5% of the total CO_2 emission followed by U.S. (20.2%), Russia (5.5%) and India (5.3%). On a larger scale, government is taking measures to limit emissions of carbon dioxide and other greenhouse gases to protect the quality of environment. According to W.H.O. report air pollution causes about 2 million premature deaths worldwide per year. The Clean Air Act is a superb representation of the government's role in air pollution prevention. It aids to influence and enforce laws that attempt to eliminate or dilute the causes of air pollution. This paper deals with the causes, effects, present status and the remedial measures to counter the existing problem of air pollution, so as to create quality atmosphere in existence.
