Air Quality Indexing For Selected Areas in Bangalore City, Karnataka State, India

Kamath , Lokeshappa

The present investigation was carried out to significant of air pollutant concentrations at Residential, Industrial &Sensitive Areas Bangalore. Sulphur dioxide (SO2), oxides of nitrogen (NOX) and R.S.P.M were collected over six sites in Bangalore. First sampling station location at Victoria Hospital, second sampling station location at Graphite Industrial Area, and third sampling station location at Amco Apartments, fourth sampling station location at Peenya Industrial Area, fifth sampling station location at Yeshwantapur Residential Area and sixth sampling station location at K.H.B Industrial Area. All the sampling stations selected are located in Residential, Industrial and Sensitive areas. Meteorological parameters like Temperature, Relative humidity, Wind speed, Wind direction & Rain fall data were also recorded simultaneously during the sampling period. Monthly and seasonal variation of these pollutions have been observed and recorded. The annual average and range values have also been calculated. It has been observed that the concentrations of the pollutants are high in summer in comparison to the Pre monsoon and post monsoon seasons. In the present study, it was noticed that the R.S.P.M levels at all selected sites exceeds the prescribed limits as stipulated by Central Pollution Control Board (CPCB) New Delhi. A part from this the SO2 and NOX levels in industrial areas remain under prescribed limits of CPCB.
