In this study the concentrations of trace metals in typical parasites of the three-spined stickleback, i.e. Schistocephalus solidus (Cestoda) and Thersitina gasterostei (Copepoda), and in the sticklebacks (infected or uninfected) were compared. Concentrations of Mn, Co, Ni, Cu, Zn, Cd and Pb were determined. The accumulations of metals suggested that S. solidus, T. gasterostei and their hosts could serve as biological indicators of heavy metal contamination.

Samples were collected .from three areas of the Baltic Sea: Kiel, Warnem?nde, Swinoujscie. The concentrations of Hg, Cd, Pb, Zn, Cu were determined in sediments and mussel tissue (Mytilus edulis); the sediment samples were also analysed for Cr, Ni, Mn, V, Fe and Mn. Differences between the metal contents in the sediment samples in the various areas were found - the highest level was noted in the Kiel region. The Warnem?nde and ?wnouj?cie areas were comparable in this respect. In the Swinoujscie and Kiel regions the level of heavy metals in sediment decreased with distance from the entrance to the ports. Since the finding did not correspond to the metal levels in the mussel tissue, using the mussel Mytilus edulis as a bioindicator of heavy metal pollution seems questionable.
