New organochlorine contaminants and metabolites in plasma and eggs of glaucous gulls ( Larus hyperboreus ) from the Norwegian Arctic
Abstract The present study investigated new or lesser‐studied and legacy organochlorine (OC) contaminants and metabolites in plasma and eggs of glaucous gulls ( Larus hyperboreus ) collected from major breeding colonies on Bear Island in the Norwegian Arctic. Hexachlorobutadiene was below the method...
