Passive air sampling was performed for urban, suburban, coastal and agriculture air during April 2009- January 2010 in Tamilnadu, southern India to know the distribution and fate of organochlorine pesticides residues. Exposed polyurethane foam samples (30 2 days) were soxhlet extracted and the extracts were analyzed by using Gas Chromatography-Mass Spectrometric method. The total concentrations of 13 organochlorine pesticides were in the range of ND - 41400 pg/m3. Dichlorodiphenytrichloroethane, dichlorodiphenydichloroethylene, heptachlor and mirex were found predominant during monsoon season. The elevated / isomer ratio of hexachlorocyclohexane (5.03) during summer revealed fresh/recent usage of hexachlorocyclohexane in coastal area. Dichlorodiphenytrichloroethanes ratio shows its fresh application in all the locations during monsoon season, which probably used to contain the diseases causing vectors. Detection of banned pesticides such as aldrin, dieldrin and heptachlor in air indicating their illegal usage/ or from old source. Furthermore, mirex an unregistered pesticide in India is being reported for the first time in air. More importantly, the obtained information will be used as a valuable baseline data for the management of atmospheric organochlorine pesticides in future.
