    Human Health Toxicity Values Used by EPA's Superfund Program

    • Learn about how PPRTV assessments are used to support the Superfund Program

A Provisional Peer-Reviewed Toxicity Value (PPRTV) is a toxicity value primarily derived for use in EPA's Superfund Program. PPRTVs are derived from a review of the relevant scientific literature using EPA methods, sources of data and guidance for value derivation.
