U.S. EPA. IRIS Toxicological Review of 1,1,2,2-Tetrachloroethane (Interagency Science Discussion Draft). U.S. Environmental Protection Agency, Washington, DC, EPA/635/R-09/001D, 2010.
The draft Toxicological Review of 1,1,2,2-Tetrachloroethane provides scientific support and rationale for the hazard and dose-response assessment pertaining to subchronic and chronic exposure to 1,1,2,2-tetrachloroethane. 1,1,2,2-Tetrachloroethane (1,1,2,2TCE; CASRN 79-34-5) is a synthetic halogenated hydrocarbon that is a colorless, nonflammable liquid at room temperature. The major use for 1,1,2,2-Tetrachloroethane was in the production of trichloroethylene, tetrachloroethylene, and 1,2-Dichloroethylene.
