Abstract
Chittagong, the commercial capital of Bangladesh, is experiencing crucial health impacts resulting from deficient air quality. The ambient air quality data for particulate matter as well as criteria of gaseous pollutants were assembled during December 2013 to December 2015 from the Continuous Air Quality Monitoring Station (CAMS) located at Agrabad, Chittagong. Analysis showed that during April- October, 24 hour average concentration of PM10 and PM2.5 were within the National Ambient Air Quality Standard (NAAQS) level but it increased about three times during the whole non-monsoon period (November-March).The highest values found of PM2.5 were 321.1µg/m3 in January, 2013 and 220.34µg/m3 in December 2015. Whether, the highest alarming concentration of PM10 was reported as 474µg/m3 in January 2007.The other gaseous pollutants such as SO2, NO2, O2 and CO remain well within the permissible limit except dry non-monsoon period. The yearly average increase of Air Quality Index (AQI) value indicates the growth rate of air pollution in Chittagong city. The main responsible pollutant for air pollution is found PM2.5.
