LSU Superfund Research: Environmentally Persistent Free Radicals

Hazardous substances at Superfund sites are frequently associated with particulate matter (PM), either in contaminated soils or sediments, emissions from treatment facilities, or dust from remediation or containment activities.  Our research focuses on newly-identified pollutant-particle systems, including environmentally persistent free radicals, that may form from the combination of pollutants and particulate matter, and their effect on respiratory and cardiac health. The ultimate goal of the research is to protect human health by providing information to be used in risk-based decisions on treatment options for Superfund wastes. The LSU Superfund Research Program is supported by  the National Institute of Environmental Health Sciences Superfund Research Program grant number P42 ES013648.
