Abstract

Ataturk
Dam Lake is on the Euphrates river in south-east Turkey. It is the largest dam
in the country. Residue levels of
organochlorine pesticides (OCPs) were determined in water, sediment and liver
tissue samples of the common carp (Cyprinus carpio Linnaeus, 1758) collected from the
littoral zone of Ataturk Dam Lake. The sampling points were chosen based on
pollution in the main agricultural sector of this region. The organochlorine pesticides extracted with
a mixture of organic solvents were quantified by Gas Chromatography–Mass
Spectrometry. Pesticide residues in the sediments were higher than the residues
in the water and fish. The highest residue in all the samples analyzed was DDE.
Ethoxyresorufin O-deethylase, glutathion S-transferase, superoxide
dismutase and catalase activities have been measured in liver samples of Cyprinus carpio. The enzyme analysis results showed that the
activities were significantly different (p˂0.05) in the stations where OCP
contaminations were highest. Differences in enzyme activity can be interpreted
to accumulation of the OCPs and the other many xenobiotics on sediment and also
in fish tissues. This study
revealed that pesticide residue levels in the fish samples were above the
maximum residue limits so could be a threat to the human health.
