  • 352 - Tracking Mercury Conversion and Distribution in Aquatic Environments -- Hsu-Kim
    Release Date: 04/03/2024

    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.

  • 318 - Combined Approach Sheds Light on Factors Controlling Stream Recovery -- Clements
    Release Date: 06/02/2021

    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 (SRP) at the Colorado School of Mines. William Clements, Ph.D., professor at Colorado State University, and two doctoral students, led the study.

  • 295 - Model Predicts PAH Levels in Important Tribal Food Source -- Anderson
    Release Date: 07/10/2019

    A sediment passive sampling model can be used to accurately predict the concentration of polycyclic aromatic hydrocarbons (PAHs) in butter clams, according to a recent Superfund Research Program (SRP) study. Led by Kim Anderson, Ph.D., of the Oregon State University (OSU) SRP Center, the research team worked closely with tribal leaders to better predict PAH levels in butter clams while having a minimal impact on this important resource.
