Health Risks

The USGS Environmental Health Program seeks to understand how environmental factors, especially contaminants and pathogens, influence human health and ecosystems. It focuses on studying the distribution and effects of toxic substances, environmental stressors, and their pathways. The program prioritizes collaboration with State, Federal and local governments; Tribes; non-government organizations...

The Energy Resources Life Cycle Integrated Science Team focuses on the potential for environmental contaminant exposures that might originate from energy resource activities including extraction, production, transportation, storage, waste management, and restoration. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are identified...

The team studies the movement of toxicants and pathogens that could originate from the growing, raising, and processing/manufacturing of plant and animal products through the environment where exposure can occur. This information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.

The Immunomodulation Integrated Science Team focuses on contaminant and pathogen exposures in the environment that might influence the immune systems of wildlife and the connection to their shared environment with humans. In collaboration with public-health officials, the Team also addresses potential human-health risks stemming from similar exposures. If actual risks are identified, this Team...

About the Research The Functional and Molecular Bioassay Core Technology Team (CTT) as part of the Environmental Health Program utilizes reporter assays, quantitative gene expression analyses, and high-throughput sequencing methods to produce functional endpoints across a broad scope of environmental topics and sample matrices.

The team studies toxicants and pathogens in water resources from their sources, through watersheds, aquifers, and infrastructure to human and wildlife exposures. That information is used to develop decision tools that protect human and wildlife health.

The team develops advanced methods to study factors driving algal toxin production, how and where wildlife or humans are exposed to toxins, and ecotoxicology. That information is used to develop decision tools to understand if ​toxin exposure leads to adverse health effects in order to protect human and wildlife health.

The Ecologically-Driven Exposure Pathways Integrated Science Team identifies how ecological pathways and physiological processes within a single organism can alter exposure and toxicity of contaminants and pathogens and seek to understand outcomes at different scales from individuals to populations and ecosystems.

U.S. Geological Survey scientists and their partners utilize laboratory and field studies and existing information to improve understanding of anticoagulant rodenticide exposure and effects to wild birds.

Environmental Health Program scientists, in collaboration with other USGS scientists, are developing complementary field and laboratory methods and capabilities to detect and quantify a range of target and nontarget per- and polyfluoroalkyl substances (PFAS) and indicator compounds at low levels (parts per trillion) in a variety of environmental matrices. The PFAS Integrated Science Team is...

Fish mercury data from State monitoring programs and research studies within the Chesapeake Bay were compiled and summarized to provide a comprehensive overview of the variation in fish mercury concentrations among species and habitats within the watershed. These data are put into context with existing health benchmarks for humans, birds, and fish. Scientists also provide a roadmap for an...

Dale Warren Griffin, a U.S. Geological Survey (USGS) environmental public-health microbiologist, was selected as a Waksman Foundation Distinguished Lecturer for the 2020–22 American Society for Microbiology (ASM) Lecture Series.
