Are Tumors in Wild Fish Harvested in the Great Lakes Region Related to Contaminants in Water Resources?

Our specialized teams of scientists are working in our laboratories and at field sites around the Great Lakes in collaboration with other federal and state resource agencies to document the prevalence of skin and liver tumors in fish. Tumor prevalence in white suckers (Catostomus commersonii), a fish harvested as a food source by local communities, is related to the degree of urbanization in the...

Systematic Approach to Understanding Tree Swallow Health in the Great Lakes Region—Science to Inform Restoration

Four papers by U.S. Geological Survey (USGS) scientists document tree swallow (Tachycineta bicolor) chemical exposure, physiological responses, and reproductive success in the Great Lakes region. These studies were designed to understand if there are health threats to swallows from contaminant exposure, and to provide resource managers with information about the actual as opposed to the perceived...

Scientists Identify Processes that Affect Fish Mercury Concentrations in Estuarine Wetlands

In a study designed to help resource managers when considering mercury exposure risk, scientists determined that sulfur cycling—a process closely related to mercury methylation rates—and ecological conditions that influence exposure are important factors affecting fish mercury concentrations in estuarine wetlands.

Selected Pharmaceuticals Not Likely to Persist in Wild Fish: Results of Uptake and Elimination Testing

Laboratory study shows that both uptake and elimination of selected pharmaceuticals within bluegill tissues is rapid indicating that persistence in bluegills in the environment is likely to be low except in those fish that reside downstream from a consistent, substantial, contaminant source.

Endocrine Active Chemical Screening Tests Optimized to Improve Precision, Accuracy, and Timeliness

Scientists optimized existing endocrine active chemical screening tests to improve their precision, accuracy, and ability to screen more samples in a shorter time-frame. The optimization was done to more rapidly obtain results from the bioassays so that research on the risks of endocrine active chemical exposure can proceed more rapidly.

Estimated Toxicity to Aquatic Organisms in Midwestern Streams Driven by Relatively Few of the 227 Pesticides Analyzed

U.S. Geological Survey (USGS) scientists measured and estimated potential acute and chronic toxicity for 227 pesticides in agricultural and urban streams in Midwestern United States. Numerous pesticides were detected at low levels. Atrazine, acetochlor, metolachlor, imidacloprid, fipronil, selected organophosphate insecticides, and carbendazim were determined to be major contributors to toxicity...
