Oil hydrocarbons in fish from Norwegian waters 1993-95

This report presents the results of a study of oil hydrocarbons in fish (haddoc, 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 p...

Description
Summary:This report presents the results of a study of oil hydrocarbons in fish (haddoc, 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 northem areas. NORSK SAMMENDRAG: Rapporten presenterer resultatene av en undersøkelse på innhold av oljehydrokarboner i fisk (hyse, torsk, sei) som ble innsamlet 1993-95 i Barentshavet, Haltenbanken, Egersundbanken, nordlige og sentrale Nordsjøen. Totalt innhold av hydrokarboner (THC) i lever varierte, men var ikke signifikant høyere i fisk fra områder med petroleumsinstallasjoner. Innholdet av aromatiske hydrokarboner var lave og uten geografiske forskjeller. Generelt ble det funnet høyere nivåer av alkylerte dekaliner i fiskelever fra Nordsjøen enn i fisken innsamlet lenger nord.
