A technology developed by NIEHS-funded Superfund Research Program (SRP) researchers may remove uranium and other heavy metals from groundwater near abandoned mines. Small business GlycoSurf, LLC worked with partners at the University of Arizona SRP Center to determine the best environmental conditions for effectively removing uranium from contaminated water.

A sophisticated biosensor may provide information about contaminant distribution in the aftermath of natural disasters, according to an NIEHS Superfund Research Program (SRP)-funded study. Led by former Texas A&M University SRP Center trainee Krisa Camargo and Michael Unger, Ph.D., from the Virginia Institute of Marine Sciences, the team demonstrated this type of tool is useful for quickly characterizing and prioritizing environmental samples for further analysis, particularly in the context of disaster research response.

Researchers from the NIEHS Superfund Research Program (SRP)-funded centers at the University of Rhode Island (URI) and Brown University developed a new type of passive sampling device for per- and polyfluoroalkyl substances (PFAS). Their new tool overcomes many limitations to traditional approaches, such as detecting short-chain PFAS and low concentrations of the chemicals in water.

An NIEHS Superfund Research Program (SRP)-funded study revealed that certain plants can be used to effectively monitor metals and other pollutants in air. Community members collected environmental data used in the study as part of the Gardenroots project, which involves residents in research activities to evaluate human and environmental health effects near former and operating mining sites in Arizona. The study was led by University of Arizona SRP Center researcher Monica Ramirez-Andreotta, Ph.D.

Researchers from NIEHS Superfund Research Program (SRP) centers at the University of California (UC), Berkeley and Columbia University used advanced analysis techniques to combine data from populations in Chile and Bangladesh. The purpose was to detect common DNA methylation (DNAm) signatures associated with arsenic exposure.

A recent NIEHS Superfund Research Program (SRP)-funded study revealed that while arsenic concentrations in community water systems (CWS) have decreased over time, certain populations are still vulnerable to elevated levels of arsenic.

A new NIEHS Superfund Research Program-funded study revealed how polycyclic aromatic hydrocarbons (PAHs) breakdown and transform in the presence of ultraviolet A (UVA) light and titanium dioxide nanoparticle pollutants. Their findings have important implications for PAH cleanup, which may not consider how PAHs transform in diverse environments.

Improved water quality and stream ecosystem recovery following treatment of mine waste depends on a mix of physical, chemical, and biological factors, according to a new study funded by the NIEHS Superfund Research Program at the Colorado School of Mines. William Clements, Ph.D., professor at Colorado State University, and two doctoral students, led the study.

A new analytical workflow, developed by NIEHS Superfund Research Program grantees, can identify and characterize previously undetected per- and polyfluoroalkyl compounds, or PFAS, in contaminated watersheds.

Exposure to inorganic arsenic before conception can alter metabolic outcomes in the offspring of mice, with different effects among males and females, according to a new study. Researchers reported, for the first time, a link between changes in gene expression in parents’ reproductive cells and diabetic indicators in offspring.

NIEHS Superfund Research Program grantees have developed novel, slow-release oxidant-paraffin candles that dissolve and degrade chlorinated contaminants in underground aquifers. The grant recipient, small business AirLift Environmental, worked with partners at the University of Nebraska-Lincoln (UNL) to optimize this groundwater clean-up method and demonstrated its effectiveness in a field study.

A new study funded by the NIEHS Superfund Research Program (SRP) shows triclosan exposure, in combination with a high-fat diet, can worsen nonalcoholic fatty liver disease. Led by Robert Tukey, Ph.D., researchers at the University of California San Diego SRP Center described the molecular mechanisms by which triclosan alters metabolism and gut microbiota, resulting in fat buildup in the liver.

Researchers from the Boston University Superfund Research Program Center developed a novel study design that generated new insight on the effects of perfluorooctanoic acid, or PFOA, on cholesterol regulation in the liver. Led by Jennifer Schlezinger, Ph.D., the team also investigated the effects of PFOA on the human peroxisome proliferator activated receptor α, or human PPARα for short, a transcription factor that regulates lipid homeostasis.

NIEHS-funded Superfund Research Program (SRP) scientists are employing a new RNA sequencing method to assess mechanisms of toxicity on a finer and more accessible scale. Researchers in SRP grantee Tim Zacharewski’s Lab at the Michigan State University (MSU) SRP Center conducted the study.

A new study from NIEHS-funded Superfund Research Program Center researchers suggests that edible sorbents may be an effective treatment to reduce heavy metal exposure from consumption of contaminated water and food. According to the researchers, this is the first evidence that edible sorbents can bind heavy metal mixtures and protect against their toxicity in a living organism.

Researchers at the University of California, Davis (UC Davis) Superfund Research Program (SRP) Center developed a new, inexpensive tool to reliably detect small amounts of tetrabromobisphenol A (TBBPA) in environmental samples. TBBPA is a flame retardant commonly found in household dust, soil, water, sewage, sludge, and sediments.

Chemical oxidation is a process commonly used to treat water contaminated with aromatic compounds like benzene. But, unexpected and potentially harmful breakdown products may result from this treatment process, according to a recent study from the NIEHS-funded University of California, Berkeley Superfund Research Program Center.

Native fungal communities point to a new way of cleaning up contaminated soil. After conducting a study to characterize fungi found in soil contaminated with polycyclic aromatic hydrocarbons (PAHs), researchers at the NIEHS-funded Superfund Research Program at Duke University discovered a group of fungi that may be promising for remediation.

Layers of clay are widely thought to protect groundwater aquifers from above-ground contaminants. But according to a new NIEHS Superfund Research Program (SRP) study, these clay layers may play a role in increasing groundwater arsenic contamination.

Superfund Research Program Center scientists developed a new platform, known as the SpheroidChip analysis method, to rapidly test for DNA damage in three-dimensional cell models. Development was led by Bevin Engelward, Sc.D., at the Massachusetts Institute of Technology.
