ABSTRACT

 

Several studies have shown that the association between atmospheric aerosols and adverse health effects and its impact on climate change, thus highlighting the need to limit the anthropogenic sources of aerosols. Kolhapur city is a one of the major industrial and commercial city in the Western Maharashtra, India which governs highest per capita income group city and now started facing the problems related to aerosols. Hence it is important to study the chemical characterization of atmospheric aerosols and its trace elements and to identify their sources so that they can be controlled appropriately to a large extent at sources before reaching to the receptor. Aerosols were collected using a High Volume Sampler (HVS) during September 2008 June 2009 at a location downwind of industrial cluster of Gokul Shirgaon and Shiroli with commercial area of Shahu Blood Bank Corner in Kolhapur. The elements like Cu, Fe, Cd, Mn, Zn, Pb, Ni etc. were analyzed by acid digestion thereby chemical characterization using AAS and the sources were identified using a receptor model like US EPA Positive Matrix Factorization (PMF 3.0). This research paper describes the results achieved by chemical characterization and thereby source apportionment of aerosols and contribution of each trace element to the respective sources.
