Abstract

Pesticides are chemical substance used to control the pest. In India almost all organochlorine pesticides (OCPs) have been banned, but some farmers and industries are still using it for agriculture purpose. OCPs are very toxic and they may affect the biota and also the human consumers. It used to control the crop pest in agricultural field which affects the yield of depending crops on bee pollination, global fish production as well as human health. We have analyzed samples of water, sediment and fish from different lakes of Ahmedabad city using Gas chromatography (GC) with flame ionization detector (FID).This study reveals that the level of dichlorodiphenyltrichloroethane, (DDT) and hexachlorocyclohexane (HCH) in studied lakes is significantly high. Periodic differences in the concentration of these pesticides were also observed. The concentration of organochlorine was advanced in summer than in the monsoon. So, it is necessary to monitor the concentration level of respected pesticides in different lakes which would be helpful in conservation of our environment.
