Key Findings Tree swallows were sampled at 6 locations in the Maumee River watershed, as part of a collaborative four-agency study on ecosystem effects of contaminants of emerging concern (CECs) on biota. This study involved samples of sediment, benthic invertebrates, and an insectivorous bird, the tree swallow. Endpoints include assessment of changes in both the tree swallow metabolome and transcriptome to determine whether perturbations can be traced from ToxCaste, an in vitro water sample assessment through mussels/clams, fish, and birds. Avian tissues and food will be analyzed for CECs with an emphasis on agricultural pesticides. Other Great Lakes’ landscape types will be sampled in future years. Products...
Description of Work U. S. Geological Survey (USGS) will identify through this project significant sources and impacts of historical and newly emerging toxics to the Great Lakes ecosystem through broad surveillance as well as laboratory and field research of tree swallows and other bird species. USGS scientists will determine the amount of exposure to and the effects of historical and emerging contaminants in Great Lakes food chains. The data will inform regulators and provide guidance on removal of Beneficial Use Impairments at Area of Concern sites around the Great Lakes. Work supported under this project is quantifying exposure to, and effects of, both historical and emerging contaminants on Great Lakes food chains...
