Oil hydrocarbons in fish from Norwegian waters 1993-95

This report presents the results of a study of oil hydrocarbons in fish (haddock, cod, saithe) collected 1993-95 from the Barents Sea, Haltenbanken, Egersundbanken, northern and central North Sea. Total hydrocarbon concentrations (THC) in liver varied, but were not significantly higher in fish from petroleum installation areas. Concentrations of aromatic hydrocarbons were low and differences between geographic areas were not found. Generally higher levels of alkylated decalines were found in fish liver from the North Sea compared to the fish from more northern areas.
