ESTIMATION OF PERSISTENT ORGANOCHLORINE PESTICIDE RESIDUES IN SELECTED FRUIT

Abstract

Organochlorine pesticides residues analysis of mango fruit samples during 2008-2009 was carried out on Gas chromatograph –ECD with capillary column .The samples were extracted in acetone and make up in hexane. Using proposed method, two laboratories (both from Kanpur) analysed mango fruit samples to evaluate some methodologies and to obtain consensus values for selected OCPs. The values of above fruits were below the maximum residues limit. The limit of detection was 0.1 to 0.5 µg / kg; where as limit of quantification 0.3 to 1.5 µg/kg were found respectively .However qualitative analysis of the standards were also carried out using kovats index. Fruits tested in our analysis do not contain any quantities of pesticide residues representing & hazard to the humans.
