WASHINGTON (EPA) – The U.S. Environmental Protection Agency (EPA) has released the final health assessment for trichloroethylene (TCE) to the Integrated Risk Information System (IRIS) database.  IRIS is a human health assessment program that evaluates the latest science on chemicals in our environment. The final assessment characterizes the chemical as carcinogenic to humans and as a human noncancer health hazard. This assessment will also allow for a better understanding of the risks posed to communities from exposure to TCE in soil, water and air.
