Confirming longstanding scientific understanding and research, the final assessment characterizes perc as a "likely human carcinogen." The assessment provides estimates for both cancer and non-cancer effects associated with exposure to perc over a lifetime. The assessment replaces the 1988 IRIS assessment for perc and for the first time includes a hazard characterization for cancer effects.
