Seasonal and spatial variability of secondary inorganic aerosols in PM at Agra: Source apportionment through receptor models.

The present study was conducted at sub-urban and rural site of Agra. The main aim of this study was to characterize WSII in terms of spatial, seasonal and formation characteristics and identify the major sources responsible for the pollution of WSII in PM particles using different source apportionment models. Since biomass burning is one of the most important sources of PM pollution in Agra, a case study was also conducted at rural site to investigate the contribution of biomass burning from cooking activities using different types of fuels.
