摘要：

To identify potential sources and accumulation features concentrations, profiles, and patterns of polychlorinated naphthalene (PCN) residues were determined in sediment, mussel, crab, plankton, and fishes from the Gdansk Basin, Baltic Sea. Different marine organisms of the lower food web clearly bioaccumulate many PCN congeners. Depending on the matrix type, PCNs substituted with four or five chlorines dominate. Due to the characteristic profile and pattern of PCN congener groups found in subsurface plankton, mussel, and surface sediments, deposition from the atmosphere is postulated to be the main source of these pollutants. Nineteen of 22 tetra-, all 14 penta-, 9 of 10 hexa-, and both hepta-CNs could be quantified in the samples. The patterns of tetra-, penta-, and hexa-CNs varied largely between the samples or groups of the samples as well as when compared to the technical PCNs formulation Halowax 1014. This implies different absorption/retention rates and/or marked, structure-dependent metabolism of some PCN congeners by marine species.
