Minerals Science Team Active
Sampling in the Animas River, Colorado
The Minerals Integrated Science Team focuses on contaminant exposures in the environment that might originate from mineral resource activities including, transportation, storage, extraction and waste management. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are identified the science produced by this team can inform how to economically and effectively minimize exposures by providing scientific data and understandings about the environmental transport, fate, and exposure pathways of contaminants.
Mineral mining is an essential part of a healthy economy. U.S. mines produced an estimated $75.2 billion in nonfuel minerals during 2017 including industrial minerals, aggregates, and metals. The mining industry and government regulators work together to prevent the release of contaminants such as metals into the environment from mining activities.
The USGS Minerals Integrated Science Team (IST), a part of the Environmental Health Program, in the Ecosystems Mission Area focuses on the lifecycle of metals and radionuclides in the environment to inform best management practices for waste materials associated with mineral extraction including transportation, storage, recycling of materials, and other activities where there are perceived or actual hazards from contaminant exposures originating from mineral resource activities.
The team works to distinguish naturally sourced toxicants in the environment from those that may originate from mineral resource activities. They use this information to understand fish, wildlife, and human exposure and to determine If their are health risks upon exposure. If health risks are identified, this Team will inform how to economically and effectively minimize risk by providing scientific data and understandings about the environmental transport, fate, and exposure pathways of contaminants. The team also directly addresses the 2012 DOI Record of Decision to understand actual versus perceived risks due to uranium mining in the Grand Canyon region. Much of this work is driven by concerns over potential mining impacts to the Grand Canyon, its natural resources, and Tribal members.
Research is accomplished at a range of scales, including laboratory-based studies, modeling, and targeted field studies in watersheds across the Nation to collectively deliver science on exposures and risks to wildlife, humans, ecosystems, and water resources. The team is unique in that it bring together geologists, hydrologists, biologists, chemists, microbiologists, ecologists, toxicologists, and geophysicists from across USGS to address this science.
The team provides science to support the utilization and protection of our Nation’s resources.
- Identify hydrologic, geochemical and biological processes that govern the source, transport, and fate of metals and radionuclides as determinants of ecosystem health
- Characterize the geochemical and biological processes governing the environmental fate, exposure, bioaccumulation, and effects of metals to reduce uncertainty and to inform risk assessment
- Characterize transport pathways of mining-related contaminants in abiotic and biotic media to improve understanding of exposure pathways and biological effects of uranium and co-occurring elements related to uranium mines in the Grand Canyon watershed.
- Develop methods and execute a geo-environmental assessment of developing undiscovered uranium deposits in the Texas Gulf coast uranium province
- Investigate multi-metal exposures, critical minerals, and multi-stressor effects on ecosystems influenced by mineral resource extraction and processing

Filter Total Items: 49Sensitivity of warm water fishes and rainbow trout to selected contaminants
Guidelines for developing water quality standards allow U.S. states to exclude toxicity data for the family Salmonidae (trout and salmon) when deriving guidelines for warm-water habitats. This practice reflects the belief that standards based on salmonid data may be overprotective of toxic effects on other fish taxa. In acute tests with six chemicals and eight fish species, the salmonid, Rainbow TAuthorsJohn M. Besser, Rebecca A. Dorman, Chris D. Ivey, Danielle M.

Biological Mn(II) oxidation produces reactive manganese oxides that help to mitigate metal contamination in the environment. Here we present the genome of Oxalobacteraceae sp.

Akob, Tsing Bohu, Andrea Beyer, Tanja Woyke, Nicole Shapiro, Alla Lapidus, Hans-Peter Klenk, Kirsten KüselCompetitive interactions among H, CU, and Zn ion moderate aqueous uptake of Cu and Zn by an aquatic insect
The absorption of aqueous copper (Cu) and zinc (Zn) by aquatic insects, a group widely used to assess water quality, is unresolved. This study examined interactions among Cu, Zn, and protons that potentially moderate Cu and Zn uptake by the acid-tolerant stonefly Zapada sp. Saturation uptake kinetics was imposed to identify competitive mechanisms. Decreasing pH reduced the maximum transport capaciAuthorsDaniel J. Cain, Marie-Noële Croteau, Christopher C. FullerInfluence of dissolved organic carbon on the acute toxicity of copper and zinc to White Sturgeon (Acipenser transmontanus) and a Cladoceran (Ceriodaphnia dubia)
We conducted acute lethality tests with white sturgeon (Acipenser transmontanus) and Ceriodaphnia dubia exposed to copper and zinc at dissolved organic carbon concentrations ranging from 0.5 to 5.5 mg/L. Dissolved organic carbon had minimal effects on zinc toxicity but did have a protective effect on acute copper toxicity, which was equal to that predicted by the copper biotic ligand model (BLM).AuthorsChris D.

The biotic exposure and uptake of radionuclides and potential health effects due to breccia pipe uranium mining in the Grand Canyon watershed are largely unknown.

The enrichment factor (EF) is a widely used metric for determining how much the presence of an element in a sampling media has increased relative to average natural abundance because of human activity. Calculation of an EF requires the selection of both a background composition and a reference element, choices that can strongly influence the result of the calculation.
