Organochlorine pesticides such as DDT and its metabolites (p,p?-DDT, o,p?-DDT, p,p?-DDD, p,p?-DDE), hexachlorocyclohexane isomers (alpha, beta and gamma (-HCH), hexachlorobenzene (HCB) and selected PCB congeners (28, 52, 101, 118, 138, 153, 180) were analysed in plankton, benthic organisms (Cerastoderma glaucum, Mytilus trossulus, Macoma balthica, Crangon crangon), muscle tissue of fish (Zoarces viviparus, Myoxocephalus scorpius, Clupea harengus, Salmo trutta) and birds (Phalacrocorax carbo, Larus ridibundus). We can observe clear differences in the bio-accumulation pattern of these toxic substances in pelagic organisms or benthos and bottom feeding fish.
