Abstract

The bioaccumulation of heavy metals in the common carp Cyprinus carpio L., 1758 was monitored to assess the pollution status in Kızılırmak. The common carp samples were captured by local fishermen and were purchased from fish markets in Bafra. Liver, gill, stomach + intestine, skin and muscles of C. carpio were analyzed for Fe, Zn, Cu, Pb, Hg and Cd using an inductively coupled plasma mass spectrometry (ICP-MS). Metal concentrations in the common carp occurred in the order: Fe>Zn>Cu>Pb>Hg>Cd. The non-essential metals Cd, Hg and Pb in edible tissues of common carp were below the detection of limits. The muscle tissues had also the lowest concentrations for essential metals. Higher concentrations of Fe, Zn, Cu and Pb in C. carpio were liver > stomach + intestine > gill > skin > muscle, while the Hg and Cd levels were liver > gill > stomach + intestine > skin > muscle, respectively.
