Air quality and exceedance factor of alwar and bhiwadi (rajasthan)

This study presents the concentration of air pollutants namely PM10, PM2.5, NO2, SOx and O3, at two cities of Rajasthan India namely Alwar and Bhiwadi and their comparison with National Ambient Air Quality Standard to assess the air quality. The results Shows that gaseous pollutants such as SOx, NO2, and O3 were within the permissible limits in both the cities but particulate matter (PM10, PM2.5)was found higher than permissible NAAQS limit in both cities. The maximum concentration of PM10and PM2.5 was found 183.80 µg/m3 and 121 µg/m3 respectively at Bhiwadi and Alwar. The study also shows that PM10 and PM2.5 are criticaly polluting the ambient air quality of both cities. It may pose detrimental effect on human and environmental health. In this study AQI and Exeedence factor was also calculated. AQI result reveal that air quality of Bhiwadi was in poor category. Exeedence Factor also indicate that PM10 and PM2.5 are the predominate cause of air pollution in Bhiwadi and Alwar cities.
