Heavy metal and trace elements in various fish samples from Sir Dam Lake, Kahramanmaraş, Turkey

Achanthobrama marmid (thorn-bream) (n:24), Chondrostoma regium (nose-carp) (n:33) and Silurus glanis (wels) (n:21), and Cyprinus carpio (carp) (n:30) were collected from Sir Dam Lake in Kahramanmaraş Province. The iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), and lead (Pb) levels were determined in the total of 108 fish samples by Atomic Absorption Spectrophotometer. The concentrations of heavy metals were expressed as mg kg(-1) wet weight of tissue. The mean Fe and Mn levels of muscle and gill of C. carpio were 0.8-5.71 and 0.30-1.96, respectively. The mean of the Fe and Mn levels of muscle and gill of A. marmid were 1.22, 5.07 and 0.38, 0.85 mg kg(-1), respectively. The ranges of mean concentrations of Fe and Mn levels in muscle and gill of C. regium were 0.91, 5.61 and 0.27, 3.42 mg kg(-1), respectively. The mean value of Fe in S. glanis gill was 1.03, which of Mn was 0.17 mg kg(-1). Fe, Mn, Co, Ni, and Pb were not detected in the muscle of S. glanis. The mean values for Co in muscle of thorn-bream, carp, and nose-carp were 0.005, 0.01, 0.0 mg kg(-1), respectively. Nickel values in the muscle were ranged between 0.38 and 1.93 in thorn-bream, 0.06 and 1.34 in carp, 0.14 and 1.89 in nose-carp, in that order. The mean Pb levels of muscle and gill of A. marmid were 0.14 and 0.29 mg kg(-1), respectively. The mean values of Pb concentration of muscle and gill for C. carpio were 0.13 and 0.50 mg kg(-1), respectively. In C. regium mean values for Pb in muscle and gill were 0.06 and 0.06 mg kg(-1), respectively. The mean value of Pb in S. glanis gill was 0.42, ranged between 0.0-0.92 mg kg(-1).
