Biomagnification of organochlorines along a Barents Sea food chain

摘要

To trace the biomagnification of organochlorines in marine food chains near Svalbard, which may lead to the high organo- chlorine concentrations in top predators from the area, we compared concentrations and patterns of organochlorines in selected taxa. The pelagic crustaceans, Calanus spp. (copepods), Thysanoessa spp. (euphausiids), Parathemisto libellula (amphipod), and the fish species, Boreogadus saida (polar cod) and Gadus morhua (cod) were selected to represent the lower trophic levels in the food web.
