The ambient air quality of Jalna city has been evaluated by means of air quality index (AQI). For one year period
ambient air concentrations of air pollutants viz. SO2, NOx, RSPM and NRSPM were monitored at residential and industrial sites
to determine AQI. The monthly, seasonal and annual AQI values determined at both residential and industrial sites pointed out
the overall air quality during the study period was comparable with slight variation. The air quality at residential site was a little
inferior than industrial site. Factors like strict government rules, efficient exhaust gas treatments, proper disposal of waste also
facilitated in dropping air pollution levels. Annual mean concentrations of SO2 and NOx evaluated at residential as well as
industrial site were observed within the permissible limits of Indian National Ambient Air Quality standards (NAAQS). While
annual mean concentrations RSPM and NRSPM at both sites violated norms. The annual AQI values 257 for residential and
224 for industrial were
