February 9, 2010 -- The classification of the dry-cleaning solvent tetrachloroethylene, also known as PERC, as "likely to be a human carcinogen" and as toxic to the nervous system is supported in the U.S. Environmental Protection Agency’s draft human health assessment for the chemical, says a new National Research Council report. The report also recommends improvements for EPA's final assessment, such as using better designed studies and stronger approaches to estimate the potential for cancer and safe inhalation and oral exposures.
