Superfund Research Program Progress in Research Webinar Part 4: Emerging Exposures

The NIEHS Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2020. In this session, being held on November 19, 2020, from 2:00 p.m. to 4:00 p.m., awardees from North Carolina State University, University of Iowa, and Louisiana State University will describe their research projects, accomplishments, and next steps.

Registration is free and open to the public. 

The North Carolina State University SRP Center, "Center for Environmental and Health Effects of PFAS," focuses on per- and polyfluoroalkyl substances (PFAS) which are ubiquitous in the environment and have been associated with health effects such as cancer and thyroid, liver, and immune system toxicity. Despite this, these compounds have not been well-studied. Center scientists are investigating human exposure levels to PFAS in impacted areas, PFAS toxicity and the underlying mechanisms behind reduced thyroid and immune function, the potential for PFAS bioaccumulation, and effective remediation approaches for PFAS contamination.

The University of Iowa SRP (ISRP) Center, "Airborne PCBs: Sources, Exposures, Toxicities, Remediation," explores polychlorinated biphenyls (PCBs) and the health impacts stemming from inhalation of these toxic chemicals. Center scientists focus on neurodevelopmental and metabolic effects, particularly in adolescents, and the relationship to novel PCB exposure pathways in buildings such as schools. They aim to identify the mechanisms behind PCB interference with lipid metabolism, define the specific environments that contribute to inhalation exposure and its importance compared to dietary exposure, and develop cost-effective strategies to remove or reduce emissions.

The Louisiana State University SRP Center, "Environmentally Persistent Free Radicals (EPFRs)," studies an emerging class of contaminants which are produced during thermal treatment of hazardous wastes and have been shown to induce cardiac and pulmonary dysfunction in exposed populations. They are investigating mechanisms of EPFR-induced health impacts, determining how EPFRs form, stabilize, and decay, and demonstrating a link between EPFR exposure and poor respiratory health in children. The research goal is to understand how to attenuate EPFR formation, facilitate EPFR decay, and limit exposure to EPFRs.
