The Government is closely monitoring the trend of various air pollutants across the country under the National Air Quality Monitoring Programme. The Monitoring network comprises manual stations spread over 300 cities in 29 States and 6 Union territories. Apart from manual stations, there are 54 Continuous Ambient Air Quality Monitoring Stations that cover 33 cities in 12 states. The monitoring network is being expanded to cover all metro cities and capital towns.
The result of the monitoring shows that, while the levels of Particulate Matters have a fluctuating trend, the value of SO2 is generally within permissible limits, while the value of NO2 is fluctuating and slightly above the permissible limits. The value of Particulate Matter is the main concern and the Government has been taking all necessary measures to mitigate this problem in a systematic manner.
