Ambient Air Quality


          Central Pollution Control Board in collaboration with Karnataka State Pollution Control Board is executing a National programme known as National Air Quality Monitoring Programme (NAMP). The network consists of 20 manual operating stations covering 11 cities/towns in Karnataka State. Including 4 Board stations, totally 24 stations are being monitored for Ambient Air Quality.                      
           The objectives of the NAMP are to determine status and trends of ambient air quality & to identify Non-attainment Stations. Developing preventive and corrective measures in places where Air Quality Standards are violated.
         Under NAMP/Board Programme three air pollutants viz., Sulphur Dioxide (SO2), Oxides of Nitrogen as NO2 & Respirable Suspended Particulate Matter (RSPM/PM10) have been identified for regular monitoring at all the locations. The monitoring of these pollutants are carried out for 24 hours (4-hourly sampling for SO2 & NO2 and 8-hourly sampling for PM10) with a frequency of twice a week, to have one hundred and four (104) observations in a year.
             The data from April 2013 to December 2013 indicates that the quantity of Respirable Suspended Particulate Matter (RSPM/PM10) exceeds the limit (100 microgram / cubic meter) at five places in Bangalore City and at two places outside Bangalore viz., Davangere,  & Hubli. Values of SO2 & NO2 are within the limits.


              Karnataka State Pollution Control Board has installed and commissioned two Continuous Ambient Air Quality monitoring stations i.e, one at City Railway Station, Bangalore and another at Nisarga Bhavan, Saneguruvanahalli, Bangalore.
