Spatial and Temporal Variations of SO2, NOx, PM10 and TSPM Concentration in Ambient Air of Jalna City, India
Abstract:
The ambient air quality monitoring data of Jalna City, India for SO2, NOx, PM10 and TSPM at two sites (residential and industrial) and over a one year period are presented within this paper. The diurnal and seasonal variation in concentrations of SO2, NOx, PM10 and TSPM has been analyzed. It has been observed that all pollutants showed higher concentration during daytime as compared to night. The seasonal cycle at both the sites generally showed for SO2, PM10 and TSPM higher concentrations during the winter season. At both the sites no distinct seasonal cycle could be detected for NOx. The annual mean concentrations recorded for SO2, NOx, PM10 and TSPM were 4.93µg/m3, 26.68µg/m3, 61.85µg/m3 and 166.11µg/m3 at residential site and 6.44µg/m3, 64.64µg/m3, 126.82µg/m3 and 306.27µg/m3 at industrial site. The annual mean concentrations of all four pollutants measured at residential site were found within the permissible limits of Indian National Ambient Air Quality Standards (NAAQS) whereas annual PM10 concentration at residential and industrial site violated the prescribed standard.
