Digestive physiology as it relates to food preference as a mechanism explaining differential bioaccumulation of lipophilic pollutants among benthic invertebrates

The objective of this proposal is to investigate benthic organisms as trophic links for lipophilic pollutant between sediments and human-consumed fish.  PCBs and PAHs has been identified as priority pollutants within the Great Lakes and have been detected in the flesh of virtually all game fishes in Lake Erie.  We will determine the chemical concentration of lipophilic pollutants in benthic biota and correlate this concentration to habitat, feeding strategy and gut juice enhanced contaminant fugacity.
