Health Risk Assessment of 1,1,2-Trichloroethane (1,1,2-TCA) in California Drinking Water

摘要

The purpose of the document is to provide information on the toxicity of 1,1,2-trichlorethane (1,1,2-TCA) and to estimate the exposure of California residents to 1,1,2-TCA. The information provided will aid the California Department of Health Services (CDHS) in developing drinking water standards for 1,1,2-TCA. The scope of the document is: a review of the existing literature pertinent to the health risk posed by the use of 1,1,2-TCA contaminated drinking water; an estimation of the 1,1,2-TCA exposure for California residents based on the most recent data on 1,1,2-TCA concentrations in California drinking water supplies; a delineation of the level of 1,1,2-TCA that may cause a noncarcinogenic health effect; and an evaluation of the carcinogenicity of 1,1,2-TCA.
