The IRIS assessment for 1,1,1-trichloroethane consists of a Toxicological Review and IRIS Summary. The Toxicological Review is a critical review of the physicochemical and toxicokinetic properties of the chemical and its toxicity in humans and experimental systems. The assessment presents reference values for the noncancer effects of 1,1,1-trichloroethane (Reference Dose and Reference Concentration), and a cancer assessment. The Toxicological Review and IRIS Summary were subject to internal peer consultation, Agency review, Interagency review, and external scientific peer review. The final products constitute the Agency's opinion on the toxicity of 1,1,1-trichloroethane. The assessment of 1,1,1-trichloroethane also served as a pilot for the implementation of certain health assessment procedures proposed in the 2002 report, "A Review of the Reference Dose and Reference Concentration Processes," prepared by the Risk Assessment Forum's Reference Dose/Reference Concentration (RfD/RfC) Technical Panel. Included in this pilot was the implementation of recommendations related to the development of toxicity values for less-than-lifetime exposure, the presentation of study findings in tabular and graphical formats, and the use of a weight-of-evidence approach for characterizing the potential for noncancer effects in exposed populations.
