Understanding Bioavailability of Arsenic and Lead in Soils at Hazardous Waste Sites

Bioavailability is a concept that is often unknown or confusing to community members impacted by metals contamination. Since bioavailability has important implications for human health and cleanup decisions at Superfund sites, it is important for impacted communities and the public to understand this concept. The University of Arizona (UA) Superfund Research Program (SRP) Center and the University of North Carolina at Chapel Hill (UNC) SRP Center collaborated to develop a factsheet to provide a brief introduction to the concept of bioavailability and its relevance to communities impacted by metals contamination. In this podcast, hear how bioavailability can affect people's exposure to metals like arsenic and lead. Plus, learn how to reduce exposure to arsenic or lead present in contaminated soil.
