The present work has been aimed at the analysis of heavy metal (Cu, Zn, Mn, Fe, Pb, Cd) fate in selected food chains comprising molluscs, their potential food, fish feeding on molluscs and predatory fish as well as mollusc faeces, Chironomidae larvae and fish feeding on them. The results generally indicate a decrease of heavy metal concentrations in the successive trophic levels. Taking into account limited bioavailability and relatively low concentrations of heavy metals in mollusc tissues, these animals are not supposed to be a threat to higher trophic levels in the Zegrzyński Reservoir ecosystem as regards metal contamination.
