Lipophilic extracts of sediment, settling particulate matter (SPM) and blue mussel (Mytilus edulis) samples, collected at coastal locations on the east and west coast of Sweden, were HPLC-separated into three fractions containing 1. monoaromatic/aliphatic, 2. diaromatic (e,g, polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins and polychlorinated dibenzofuraus (PCDDs/Fs)), and 3, polyaromatic compounds (e,g, polycyclic aromatic hydrocarbons (PAHs)), The fractions were tested for dioxin-like effects using a sensitive bioassay, based on EROD-induction in cultured chicken embryo livers, The concentrations of PCDDs/Fs, PCBs and 15 PAHs in the samples were also determined, The polyaromatic fractions of the sediment samples were more potent as EROD-inducers than the diaromatic fractions, Only a small part of the EROD-induction caused by the polyaromatic fractions could be explained by the analysed PAHs in the samples, indicating presence of non-quantified polyaromatic EROD-inducing compounds in the samples, A greater pollution by EROD-inducing diaromatic and polyaromatic compounds on the east coast site than on the west coast site was seen, The filtration activities and faeces production of the mussels on the east coast experimental site increased the sedimentation of PCDDs/Fs, PCBs and PAHs, The described bioassay proved very useful in the assessment of dioxin-like compounds in both abiotic and biotic samples from the marine environment,
