Environmental pollution remains a serious issue in the developing world, affecting the lives of billion people, reducing their life expectancy, and damaging children's growth and development. The Government has recently revised the National Ambient Air Quality Standards (NAAQS) and limits for 12 pollutants have been notified. Area classification based on land -use has been done away with so that industrial areas have to conform to the same standards as those for residential areas. The annual average norms for Lead, Nitrogen Dioxide (No2), Arsenic, Nickel, Benzene and Benzo(a ) Pyrene in ambient air are at par with the European Union norms. However, the norms for Particulate Matter having size less than 10 micron (PM10 ) and Particulate Matter having size less than 2.5 micron (PM2..5) are more relaxed than EU norms. Indian norms for Carbon Monoxide, Ozone and Sulphur Dioxide (SO2) are more stringent than EU norms. Ammonia is additionally included in our NAAQS.
