Comparative study of ambient air quality of Jalna city was carried using air quality index (AQI). Air pollutants concentration-SO2, NOx, RSPM and NRSPM at residential and industrial sites for years 2016 and 2017 were compared. The monthly, seasonal and annual AQI values determined at both residential and industrial sites for these years. Results suggest better air quality at residential site for the year 2017 than 2016. While at industrial site better air quality was observed for the year 2016 than 2017. Government regulations, effective treatments in industries, appropriate waste disposal helped in minimization of pollution levels. For both the years and at both sites annual mean concentrations of SO2 and NOx were found within the permissible limits of Indian National Ambient Air Quality standards (NAAQS), although for both the years and at both the sites RSPM and NRSPM concentrations were observed above the norms. The annual AQI value at residential site was higher 128 for 2016 compared to 120 for 2017. While at industrial site AQI value 88 was found lower for 2016 compared to higher 126 for the year 2017.
