Ataturk Dam Lake is an important ecosystem located in south-eastern Anatolia in Turkey. In this study, concentration of Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were determined in kidney, liver, gill and muscle of Tor grypus which has great economic value in Ataturk Dam Lake. Heavy metal levels in fish samples were analyzed by inductively coupled plasma spectroscopy (ICP). The metal accumulation in the liver, kidney and gill of Tor grypus was found to be quite high in comparison to the muscle. All metal levels detected in tissues were the limits for fish proposed by FAO/ WHO, EU and Turkish Food Codes and safe within the limits for human consumption in the edible parts of fish species in the region.
