In 2007 archived great blue heron eggs collected from Indiana Dunes National Lakshore, IN, in 1993 were analyzed for 11 perfluorinated compounds (PFCs) and 7 polybrominated dephenyl ethers (PBDEs). Concentrations of perfluorooctane sulfonate, the major contributor to total PFC concentrations, were below the toxicity thresholds estimated for bobwhite quail and mallards, but within the toxicity threshold estimated for white leghorn chickens. The ranking of PBDE congener concentrations by percent concentration was conissten with the Penta-PBDE formulation. Total PBDE concentrations in great bue heron eggs from Indiana Dunes were elevated and probably reflect local contamination from highly urbanized and industrialized inputs into Lake Michigan. Polybrominated diphenyl ether concentrations were within levels associated with altered reproductive behavior in other avian species and based on trends in other Great Lakes birds are probably higher today.
