Provisional Peer-Reviewed Toxicity Values for Vinyl Bromide


EPA announced the release of a Provisional Peer-Reviewed Toxicity Value assessment for Vinyl Bromide (CASRN 593-60-2).


Provisional Peer-Reviewed Toxicity Value (PPRTV) assessments like Vinyl Bromide (CASRN 593-60-2) support the EPA's mission to protect human health and the environment by identifying and characterizing the health hazards of chemicals of concern to the Superfund Program, and provide an important source of toxicity information and toxicity values. 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 use Agency methodologies, practices, and guidance for developing toxicity values.


The purpose of this document is to provide support for the hazard and dose response assessment pertaining to chronic and subchronic exposures to substances of concern, to present the major conclusions reached in the hazard identification and derivation of the PPRTVs, and to characterize the overall confidence in these conclusions and toxicity values.
