ABSTRACT

Heavy metals (Cu, Zn, Fe, Ni, Cr, Sr, Cd, Co, Pb, and Mn) were mostly accumulated in superficial fish tissues: gills, fins, and scales. Their concentrations were higher organs with a higher functional activity: liver, kidney, spleen, and gonads. A relatively high accumulation was also found in the intestine. The depositing capacity of tissues proved species specific. As compared with predators, benthophagous species accumulated more toxic elements.
