National Ambient Air Quality Standards.pdf

National Ambient Air Quality Standards (NAAQS) are standards for air quality that are set by the Central Pollution Control Board (CPCB) that are applicable all over the country. Topics related to the environment, especially, air pollution/quality are essential for the UGC NET ENVIRONMENTAL SCIENCES .

National Ambient Air Quality Standards (NAAQS)
The NAAQS set by the CPCB are applicable to the whole country. The CPCB draws this power from the Air (Prevention and Control of Pollution) Act, 1981.

These standards are essential for the development of effective management of ambient air quality.
The first ambient air quality standards were developed in 1982 pursuant to the Air Act.
Later, in 1994 and 1998, these standards were revised. The latest revision to the NAAQS was done in 2009 and this is the latest version being followed.
The 2009 standards further lowered the maximum permissible limits for pollutants and made the standards uniform across the nation. Previously, industrial zones had less stringent standards as compared to residential areas.
The compliance of the NAAQS is monitored under the National Air Quality Monitoring Programme (NAMP). NAMP is implemented by the CPCB.
The current standards (2009) comprise 12 pollutants as follows:
Particulate Matter 10 (PM10)
Particulate Matter 2.5 (PM2.5)
Nitrogen Dioxide (NO2)
Sulphur Dioxide (SO2)
Carbon Monoxide (CO)
Ozone (O3)
Ammonia (NH3)
Lead (Pb)
Benzene
Benzopyrene
Arsenic
Nickel
