Residues of organochlorine pesticides (OCPs) were detected in water, sediment and liver tissue samples of the commoncarp (Cyprinus carpio Linnaeus, 1758) collected from the Ataturk Dam Lake. Ethoxyresorufin O-deethylase, glutathion Stransferase, glutathion reductase, superoxide dismutase, catalase and carboxylesterase activities have been evaluated in liverof Cyprinus carpio. The level of OCPs were determined by Gas Chromatography-Mass Spectrometry. No pesticide residuewas determined in the water samples and residues in the sediments were higher than in the fish. In the wet season, the level ofpesticides were higher than in the dry season. The concentrations of OCPs were highest in the Akyazı and Bozova areas.Enzyme analysis results showed that the activities were different from region to region and generally higher in Akyazı andBozova than the other areas. This study is the first study that determines the levels of OCPs of sediment, water and fish inAtaturk Dam Lake and presents pesticide residue levels in the fish samples were above the maximum residue limits so couldbe a threat to the human health. The presence of OCPs indicates the need for continuous monitoring of the Lake fishpopulation to safeguard the health of the consumers.
