Test data for 1,1,2-TCE were submitted by the Hazardous Air Pollutant (HAP) Task Force and the Saphire Grouptm (prepared for the HAP Task Force). These data were submitted pursuant to a TSCA section 4 ECA/Order and were received by EPA on January 21, 2004, and August 18, 2003. The submission includes the following final reports titled:

1. “Route-to-Route Extrapolation of 1,1,2-TCE Studies, from the Oral Route to Inhalation Using Physiologically Based Pharmacokinetic Models; Carcinogenicity.”

2. “Amended Report; Pharmacokinetics of 1,1,2-TCE in Rats and Mice.”

3. “Physiologically Based Pharmacokinetic Model Development, Simulations, and Sensitivity Analysis for Repeated Exposure to 1,1,2-TCE.”
