ABSTRACT
The ambient air quality of Jalna city has been assessed by using air quality index (AQI). For determining AQI the ambient air concentrations of air pollutants viz. SO2, NOx, RSPM and NRSPM were monitored at residential and industrial sites for one-year period. The monthly, seasonal and annual AQI values determined at both residential and industrial sites indicated that the overall air quality at residential and industrial sites during the study period was comparable with not too much variations. The air quality at residential site was slightly better than industrial site. Strict government regulations, effective treatments in plants, adequate disposal of waste also helpful in reducing air pollution levels. Annual mean concentrations of SO2 and NOx determined at residential as well as industrial site were found within the permissible limits of Indian National Ambient Air Quality standards (NAAQS). While RSPM and NRSP Manual mean concentrations at both residential and industrial were violated. The annual AQI values 120 and 126 were recorded for residential and industrial site respectively due to higher RSPM.
Key words: Ambient air quality (AQI), Gaseous pollutants-SO2, NOx, Particulate pollutants, RSPM-Respirable Suspended Particulate Matter, NRSPM- Non Respirable Suspended Particulate Matter
