Determination of Heavy Metals in of Fishes, Water and Sediment from the Demirköprü Dam Lake (Turkey)

Abstract

In this study, concentrations of heavy metals were measured in the surface water, sediment and fi sh (Cyprinus carpio) from the Demirköprü Dam Lake (Manisa, Turkey). The obtained results showed that, in general, the heavy metal (Cd, Cr, Cu, Fe, Ni, Pb) concentrations in water did not exceed WHO (World Health Organization, 1999), EC (Europe Community, 1998), EPA (Environment Protection Agency, 2002) and TSE-266 (Turkish Standard, 1997), WPCL (Water Pollution Control Legistation, 2004), CIW (Criterions of the Irrigation Water, 1997) guidelines. Heavy metal concentrations were found decrease in sequence of the surface water Fe > Pb > Cu > Ni > Cr > Cd, the Cyprinus carpio samples, in the muscle Fe > Cu > Ni > Cr > Pb > Cd, in the gill Fe > Ni > Cu > Pb > Cr > Cd, in the stomach-intestine Fe > Cu > Pb > Ni > Cr > Cd, in the air sac Fe > Pb > Cu > Ni > Cr > Cd, in the heart Fe > Ni > Pb > Cu > Cr > Cd, in the liver Fe > Cu > Ni > Pb > Cr > Cd. These obtained results show that, the heavy metal concentrations exceded the tolerable values provided by the international institutions. Generally, heavy metal concentration of the sediments were found decrease in sequence of Fe > Ni > Cu > Cr > Pb > Cd
