The National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) produces a monthly Research Brief Podcast that highlights the research of SRP grantees. The SRP is a network of university grants that seek solutions to the complex health and environmental issues associated with the nation's hazardous waste sites. The research conducted by the SRP is a coordinated effort with the Environmental Protection Agency, which is the federal entity charged with cleaning up the worst hazardous waste sites in the country.

    Environmental Factors Alter PFAS Removal by Specialized Nanomaterials

    Environmental Factors Alter PFAS Removal by Specialized Nanomaterials

    Researchers funded by the NIEHS Superfund Research Program (SRP) revealed how characteristics of water treatment systems may alter the ability of novel nanomaterials to remove PFAS. Scientists should be aware of factors like water pH ' a measure of acidic or basic conditions ' or salt level to ensure that these nanomaterials effectively remove PFAS in aqueous environments, according to the team based at the State University of New York at Buffalo.

    High Seafood Diet May Lead to Increased PFAS Exposure

    High Seafood Diet May Lead to Increased PFAS Exposure

    A study funded by the NIEHS Superfund Research Program (SRP) found that consuming some types of commercial seafood in high quantities may increase the risk of PFAS exposure. Led by Celia Chen, Ph.D., Kate Crawford, Ph.D., and Megan Romano, Ph.D., at Dartmouth College, the research team believes their findings can support the development of consumption guidelines to protect communities from further PFAS exposure.

    Engineering Hydrogel Beads to Enhance Bioremediation of Groundwater Contaminant

    Engineering Hydrogel Beads to Enhance Bioremediation of Groundwater Contaminant

    Oregon State University scientists and engineers developed an approach to cleaning polluted groundwater that uses tiny beads containing chemical-eating bacteria. In this study, funded by the NIEHS Superfund Research Program (SRP), the team identified a formula to maximize bead durability and bioremediation, or the removal of contaminants using bacteria.

    Tracking Mercury Conversion and Distribution in Aquatic Environments

    Tracking Mercury Conversion and Distribution in Aquatic Environments

    NIEHS Superfund Research Program (SRP)-funded researchers, led by Heileen Hsu-Kim, Ph.D., of the Duke University SRP Center, provided insight into how and at what timescale mercury changes within a wetland ecosystem. They found mercury from different sources is converted into other mercury forms that eventually have similar properties. This finding can inform environmental management or pollution control strategies.

    Using Earth Materials to Remove Metals Near Abandoned Mines

    Using Earth Materials to Remove Metals Near Abandoned Mines

    NIEHS Superfund Research Program (SRP)-funded researchers developed a new strategy that uses limestone and a naturally occurring mineral to clean up water contaminated with arsenic and uranium — two of the most frequently detected drinking water pollutants in Tribal communities.

    New Model Estimates the Effects of Dioxin on Liver Cholesterol

    New Model Estimates the Effects of Dioxin on Liver Cholesterol

    Scientists funded partly by the NIEHS Superfund Research Program (SRP) developed a computer model to determine the health effects of exposure to dioxins. Researchers use the model to combine data on exposures and on known health outcomes to assess the overall risk chemicals could pose to health.For this study, researchers at the Michigan State University SRP Center and Emory University created a computational model to show how the highly toxic chemical 2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD) affects biological processes that increase cholesterol levels in the liver.
