Variations in Mass of the PM10, PM2.5 and PM1 during the Monsoon and the Winter at New Delhi
PM 10 , PM 2.5 and PM 1 mass concentrations have been measured at Delhi (28°35′N; 77°12′E) during the August to December 2007. The running mean of PM 10 , PM 2.5 and PM 1 data shows large variations. The PM 10 , PM 2.5 and PM 1 were ranged from 20 to 180 μg/m 3 during the monsoon and from 100 to 500...
