Fish Contaminant Fate and Transport

Our laboratory has been investigating the fate and transport of environmental contaminants for 20 years, and have moved from identifying pollutant sources, to understanding the dynamics of organic chemicals in aquatic food webs. Our current research is focused on contaminant bioaccumulation and biotransport in macroinvertebrates and fish. The Environmental Chemistry Laboratory is working with the USGS on PCB congener bioaccumulation in Great Lakes fish, and looking at the differences in contaminant accumulation between males and females. We are also evaluating, in collaboration with researchers at Notre Dame, whether or not Pacific salmon in the Great Lakes system are serving as biotransporters of contaminants to resident brook/brown trout streams. As part of this ongoing research, in 2015 we will be further examining congener patterns, and will be submitting a paper on the imprinting of basin specific congener patterns in receiving streams.
