Abstract

To understand how air pollution varies in emerging countries like India and its capital cities, monthly air-quality data with high temporal and geographical precision is necessary. For many Indian cities, yearly fluctuations in air pollution are still indeterminate. Spatial and temporal variations of seven air pollutants in fifteen monitoring station across the metropolitan city Bangalore during the year 2018 were analysed. The annual mean mass concentrations of PM2.5 and PM10 were 63.1 ± 18.9 µg m-3 and 90.8 ± 18.4 µg m-3 , respectively, exceeding the Indian National Ambient Air Quality Standards established by the Central Pollution Control Board. The annual mean concentrations of SO2 were 2.36 ± 0.1 µg m-3 , NO2 31.34 ± 3.7 µg m-3 , CO 1.13 ± 0.2 µg m-3 , NH3 23.97 ± 3.7 µg m-3 , and lead values are 0.24 ± 0.5 µg m-3are below the national limit. Saneguruvanahalli and Banasawadi Police Stations had lower concentrations of air pollutants, except for PM2.5, than other stations in Bangalore, resulting in better air quality. Seasonally, the maximum PM2.5 concentrations were found at ITPL Whitefield in the spring, followed by the autumn seasons. This analysis provides the basis for the pollutant to be considered in the formulation of future Bangalore air mitigation strategies.
