Abstract. By applying mathematical approaches we studied the distribution of copper in organs and tissues of Alburnus alburnus and Perca fluviatilis from "Topolnitsa" Dam Lake. A deposit of the metal in the kidneys and liver was recorded. We found out that the surveyed species are macroconcentrators of cadmium and zinc and there is a process biomagnification of heavy metals in the trophic levels.
Key words: Pices, Alburnus alburnus, Perca fluviatilis, heavy metals, transfer.
