No abstracts are to be cited without prior reference to the author.Polyaromatic hydrocarbons (PAHs) are environmental contaminants that are released into the marine environment through oil spills, domestic heating, traffic and power plants. Fish exposed to PAHs show only trace amounts of these compounds in their tissues. Instead, PAHs are readily transformed into more hydrophilic metabolites, which are excreted through bile. Thus fish bile PAH-metabolites can be used as a biomarker of exposure of fish to PAHs in the field. For background knowledge perch were exposed in laboratory to two concentrations (0.5 and 2.5 mg per litre) of Russian crude oil for one and three weeks and sampled thereafter. In addition, perch were sampled near an oil refinery and at a reference site in the Gulf of Finland, and salmon were sampled in four areas of the Baltic Sea. PAH-metabolites in bile were analysed by a HPLC method with fluorescent detection. Four PAH-metabolites were detected in bile of exposed perch and the ...
