Measurement of Heavy Metals in Fish from the Tajan River

S. Zare and A.G. Ebadi

Abstract

In this study samples of three commonly consumed fish ( Sefid, Kafal and Koli ) were analysed for concentrations of heavy metals (Pb, Cd and Cu). Fish were captured using electric fishing on four sites along the Tajan River (Mazandaran province). The concentrations of heavy metals were determined by atomic absorption spectrophotometer. Samples contained detectable concentrations of heavy metals but at concentrations below the Maximum Residue Limit (MRL). Cadmium concentrations were below the MRL. Lead contamination showed no significantly different. Copper contamination was correlated with the localization of industrial plants. With respect to concentrations of pollutants in the Tajan river should not pose a serious threat to the fishes and public health.
