Small Mammal Bioaccumulation of Contaminants and Radioactivity near a Mixed Low-level Radioactive and Hazardous Chemical Waste Site—Science to Understand Wildlife Exposure to Environmental Contaminants
Pilot-study results document the presence, concentrations, and distribution of polyfluoroalkyl substances (PFASs), polychlorinated biphenyls (PCBs), and tritium in small mammals, insects, plants, and soils adjacent to a mixed low-level radioactive and hazardous chemical waste site near Beatty, Nevada, and provide a better understanding of potential exposure pathways.
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...
Bioactive Chemicals Research Laboratory
The Bioactive Chemicals Research Laboratory applies a collaborative transdisciplinary approach to conduct research to minimize the risk to human and aquatic organism health from exposure to contaminants in water supplies.
Michigan Bacteriological Research Laboratory
Microbiologists at the Michigan Bacteriological Research Laboratory (MI-BaRL) use a wide array of traditional and modern molecular approaches to evaluate microbial pathogens and antimicrobial resistance pathways in the environment.
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.
Program Scientist Receives Meritorious Service Award
Dr. Isabelle M. Cozzarelli received the U.S. Department of Interior's second highest honorary award—the Meritorious Service Award—for her numerous contributions to understanding the biogeochemical controls of contaminant degradation in groundwater and near-surface environments.
Assessing Contaminant Hazards Without a Critter—Advancements in Alternatives to Animal Toxicity Testing
During the past two decades, great strides have been made toward the development and use of ecotoxicity testing methods that reduce animal use or replace animals altogether with in vitro tests or in silico models.
