Polychlorinated biphenyl congener distributions in burbot: Evidence for a latitude effect
Abstract The authors compared the distributions of the congeners of polychlorinated biphenyls (PCBs) detected in whole‐body samples of burbot ( Lota lota ) from Great Slave Lake and Lake Erie. Total PCB concentrations in Great Slave Lake burbot were about one‐sixtieth of the concentrations in Lake E...

The results generally supported a prediction of higher proportions of lower‐chlorinated PCB homologs in organisms in remote polar areas. However, the latitudinal effect on PCB congener distribution may be more complex than that portrayed in previous studies.
