  • 348 - Environmentally Persistent Free Radicals, PAHs Interact to Increase Toxicity of Particulate Mixtures -- Lomnicki
    Release Date: 12/13/2023

    Toxic air pollutants called environmentally persistent free radicals (EPFRs) may react with certain polycyclic aromatic hydrocarbons (PAHs) on the surface of airborne particles to form more toxic chemicals, according to researchers funded by the NIEHS Superfund Research Program (SRP). The study, led by Slawomir Lomnicki, Ph.D., of the Louisiana State University SRP Center, demonstrated that interactions between components of fine particulate matter mixtures may enhance their overall toxicity.

  • 299 - Modeling Approaches Estimate Exposure and Simulate Impacts on Health -- Levy
    Release Date: 11/06/2019

    Researchers from the Boston University (BU) Superfund Research Program (SRP) Center developed and applied novel statistical models to cost-effectively predict chemical exposures and their associated harm to human health in large populations. These statistically powerful approaches can address the challenges of measuring exposures for large populations and quantifying the health benefits of exposure reduction.
