U.S. EPA. IRIS Toxicological Review of Chloroprene (Interagency Science Discussion Draft) . U.S. Environmental Protection Agency, Washington, DC, EPA/635/R-09/010D, 2010.
The draft Toxicological Review of chloroprene provides scientific support and rationale for the hazard and dose-response assessment pertaining to chronic exposure to chloroprene. Chloroprene (C4H5Cl) is a volatile, flammable liquid used primarily in the manufacture of polychloroprene or neoprene rubber. The latter is used to make diverse products, such as tires, wire coatings, and tubing. Human health risk concerns for chloroprene are primarily related to exposures via effluent and emissions from facilities that use chloroprene to produce polychloroprene elastomers or transport the product, although these exposure concerns have not been well characterized.
This assessment contains the derivation of a chronic inhalation reference concentration (RfC) and chronic cancer inhalation unit risk.
