Residues of organochlorine pesticides (OCPs) were detected in water, sediment and liver tissue samples of the common
carp (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 liver
of Cyprinus carpio. The level of OCPs were determined by Gas Chromatography-Mass Spectrometry. No pesticide residue
was determined in the water samples and residues in the sediments were higher than in the fish. In the wet season, the level of
pesticides 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 and
Bozova than the other areas. This study is the first study that determines the levels of OCPs of sediment, water and fish in
Ataturk Dam Lake and presents pesticide residue levels in the fish samples were above the maximum residue limits so could
be a threat to the human health. The presence of OCPs indicates the need for continuous monitoring of the Lake fish
population to safeguard the health of the consumers.
