Ambient Air Quality (AQI) of Belagavi city and its surroundings was monitored using a set of dust samplers, viz., APM-460, APM-550 and APM-433. The pollutants considered for the assessment of air quality were sulphur dioxide (SO2), nitrogen dioxide (NO2), ammonia (NH3) and particulate matter (PM10 and PM2.5) which gave a measure of pollution content in the air. The sampling sites have been monitored for 24 hours on an 8 hourly basis in three different seasons in 2013 and 2014. Air quality was quantified in terms of concentrations of PM10, PM2.5, NO2, SO2 and NH3. The results revealed that locations near Bus station and Macchae industrial area lie in the range of Moderate Air Pollution and Autonagar, Sadashivnagar and Kangralli village lie in the range of Light Air Pollution. Annual Air Quality index of presently selected sites of Belagavi has been determined to assess the degree of atmospheric pollution.
