Transfer of polychlorinated biphenyls from marine sediment to a benthic fish (Pleuronectes yokohamae)†
Abstract
We examined the transfer of polychlorinated biphenyls (PCBs) from suspended and bottom sediments to a benthic fish species (Pleuronectes yokohamae) by conducting laboratory experiments and determined the distribution of PCBs in the fish tissues. The mean total PCB concentrations in individual tissues and whole body of the fish exposed to bottom sediment (including suspended sediment) in the bottom sediment tank for 28 days increased to levels 3–5 times the initial concentrations, whereas those in the fish exposed only to suspended sediment in the suspended sediment tank did not increase. The congeners #52/#69, #70, #66, #101, #122/#123, and #153 were the most abundant congeners in the fish from the bottom sediment tank, reflecting the congeners that were abundant in the
