The Zn, Cd, Pb, Cu, Mn, and Fe concentrations in sediments, bottom waters, and benthic macroinvertebrates ( Amphipoda, Bivalvia, Gastropoda, Hirudinea , and Oligochaeta ) collected at six coastal stations in the Eastern Gulf of Finland were determined with the aim to reveal the features of heavy metals bioaccumulation in the macrozoobenthos. It was shown that benthic macroinvertebrates accumulate Mn, Fe, and Zn more actively than Pb, Cu, and Cd, while Hirudinea and Oligochaeta worms have enhanced accumulative capacities as compared to amphipods and mollusks. A close relationship was found between the Zn and Pb concentrations in the sediments and amphipods, but for the other elements no reliable relationship was observed. It was recommended to use organisms of other trophic levels along with zoobenthos and data on heavy metal concentrations in sediments for chemical monitoring of coastal waters.
