Isomer-specific determination of polychlorinated dibenzofurans (PCDF) and dibenzo-p-dioxins (PCDD) was carried out in 37 samples of different fish species, crustaea and mussel from a fjord area contaminated by waste water from a Mg-factory. In addition 6 sediment samples were analysed. The tetra- and pentachlorodibenzofuran isomer pattern of the Mg-process is very characteristic and dominated by isomers with chlorine in the positions 1,2,3,7 and/or 8. Very similar patterns were found in sediment, crustacea and mussel samples up to 15 km from the factory. Nearly all isomers were present in crab, shrimp and mussel while fish samples contained mainly 2,3,7,8-substituted congeners. The isomer distributions and concentration levels for different species and tissues with high and low fat content are presented. The applied analysis techniques and the quality assurance procedure as well as practical problems are described in detail. The found levels varied between low ppt- and high ppb-levels for single isomers.
