Provisional Peer-Reviewed Toxicity Values for p-α,α,α-Tetrachlorotoluene

Impact/Purpose:
A Provisional Peer-Reviewed Toxicity Value (PPRTV) is defined as a toxicity value derived for use in the Superfund Program. PPRTVs are derived after a review of the relevant scientific literature using established Agency guidance on human health toxicity value derivations. All PPRTV assessments receive internal review by at least two Center for Public Health and Environment Assessment (CPHEA) scientists and an independent external peer review by at least three scientific experts.
Description:
Provisional Peer-Reviewed Toxicity Value (PPRTV) assessments support the EPA mission to protect human health and the environment by identifying and characterizing the health hazards of chemicals of concern to the Superfund and RCRA Programs, and providing an important source of toxicity information and toxicity values for such chemicals. PPRTVs [provisional oral reference doses (p-RfDs), inhalation reference concentrations (p-RfCs), cancer risk values, and screening values] are derived after a review of the relevant scientific literature and using Agency methodologies, practices, and guidance for the development of toxicity values. Other EPA programs or external parties who choose of their own initiative to use PPRTV values are advised that Superfund resources will not be used to respond to challenges of these PPRTVs used in a context outside of the EPA Superfund Program.
