Research Briefs by Year: 2021

Superfund Research Program

  • 317 - New Technique Sheds Light on PFAS in Coastal Watersheds -- Sunderland
    Release Date: 05/05/2021

    A new analytical workflow, developed by NIEHS Superfund Research Program (SRP) grantees, can identify and characterize previously undetected per- and polyfluoroalkyl (PFAS) compounds in contaminated watersheds. The team is led by Elsie Sunderland, Ph.D., of the University of Rhode Island SRP Center, and SRP trainee Bridger Ruyle, a doctoral student at Harvard.

  • 316 - Arsenic Exposure Before Conception May Trigger Diabetes in Male Offspring -- Fry, Styblo
    Release Date: 04/07/2021

    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.

  • 315 - Modeling and Field Tests Yield Promising Results for Aquifer Clean Up -- Christenson, Comfort
    Release Date: 03/03/2021

    NIEHS Superfund Research Program (SRP) 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.

  • 314 - Triclosan and a High-fat Diet Worsen Liver Disease in Mice -- Tukey
    Release Date: 02/03/2021

    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.

  • 313 - New Model to Examine PFAS Sheds Light on Lipid Disruption Mechanisms -- Schlezinger, Webster
    Release Date: 01/13/2021

    Researchers from the Boston University (BU) Superfund Research Program (SRP) Center developed a novel study design that generated new insight on the effects of perfluorooctanoic acid (PFOA) on cholesterol regulation in the liver. Led by Jennifer Schlezinger, Ph.D., the team also investigated the molecular mechanisms of action, focusing on effects of PFOA on the human peroxisome proliferator activated receptor α (hPPARα), a transcription factor that regulates lipid homeostasis.
