Selected metals (Al, Fe, Mn, Zn, Cu, Pb, Cd, Hg, Ni, Mg, Cr, V, Li, K, Ca, Na) were determined in the muscle tissue of freshwater fish species: pike, bream, perch and common carp, harvested from natural waters of West Pomerania, Poland. Levels of Cd and Pb were determined by Graphite Furnace Atomic Absorption Spectrometry (GF-AAS), Hg by the cold vapour technique after Hg ions reduction with SnCl2 (CV-AAS), and the other metals by Inductively Coupled Plasma - Atomic Emission Spectrometry (ICP-AES). The data indicate that the examined fish were not polluted with metals, and the mean concentrations of toxic metals (Pb, Cd, Hg) were within the limits for fish and fishery products specified by EU legislation, so the fish were safe for human consumption
