Abstract

Urban air quality is a problem of foremost concern in many small and big cities in developing countries, including India. Increasing levels of particulates, oxides of sulphur and nitrogen are accountable for non-compliance of national ambient air quality standards. In order to assess the impact of urban air pollution, 20 sampling locations were selected for Vadodara city and ambient air quality was monitored twice a week from October 2017 to February 2018. Using the measured values of PM10, PM2.5, SO2, NOX, HCs, and CO, Air Quality Index has been calculated. The NOX and SO2levels are found to be complying with the NAAQ standards during the entire study period. The suspended and respirable particulates are found to be non-complying the standard limits for residential and industrial areas. The computed AQI reveal values in the range of 49-130, which indicate the presence of moderately polluted to significant pollution levels. The computed values of Exceedence factors reveal that suspended and respirable particulates are substantially responsible for causing air pollution.
