Abstract:PM2.5, PM10 mass levels at six and BC levels at one station were monitored at the tropical megacity, Bengaluru, India, for the year 2019. The annual average levels of PM2.5, PM10 and BC were 31, 73 and 2.72 µg/m3 respectively. PM2.5 levels were within the Indian National Ambient Air Quality Standard (INAAQS) value of 40 µg/m3 whereas that of PM10 exceeded INAAQS level of 60 µg/m3 for the year 2019 for all six stations. The season-wise diurnal variability of PM and BC shows bimodal peaks, first one in the morni… Show more
