Abstract
Two adult White-tailed eagles Haliaeëtus albicilla from the breeding sites of the coastal area of the southwestern Baltic Sea, and two from the breeding sites ∼ 200 km south of the coast (Province of Gorzów) have been analysed for ΣDDT, PCBs, HCB, ΣBHC, Hg, Pb, Cd, Cu, Zn, Mn, and Fe. The elevated levels of mercury found in tissues of birds from the coast are probably still among the causes of the extermination of the Baltic population of White-tailed eagles. Levels of DDE in adult birds found dead on the coast of the southwestern Baltic Sea in 1980s were half those in Sea Eagles from the Stockholm Archipelago in the 1960s. Levels of PCBs are comparable to those in White-tailed eagles from the Archipelago of southwestern Finland in the 1980s, and for some birds are higher than in birds from the Stockholm Archipelago in the 1960s. DDE, PCB, and mercury levels found in tissues of White-tailed eagles from the breeding sites toward south of the coastal area are much less than in eagles breeding along the coast.
