NIEHS Superfund Research Program - Research Brief Podcasts episodes
- Combined Approach Sheds Light on Factors Controlling Stream RecoveryImproved 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.6 min
- New Technique Sheds Light on PFAS in Coastal WatershedsA 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.5 min
- Arsenic Exposure Before Conception May Trigger Diabetes in Male OffspringExposure 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.5 min
- Modeling and Field Tests Yield Promising Results for Aquifer Clean UpNIEHS 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.6 min
- Triclosan and a High-fat Diet Worsen Liver Disease in MiceA 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.5 min
- New Model to Examine PFAS Sheds Light on Lipid Disruption MechanismsResearchers 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.6 min
- Improved Sequencing Method Leads to Advancements in Toxicology ResearchNIEHS-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.5 min
- Edible Sorbents May Protect Against Metal ToxicityA 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.5 min
- New Tool Monitors a Flame Retardant in SedimentResearchers 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.5 min
- Toxic Breakdown Products Formed During Contaminant Clean-UpChemical 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.4 min
