The draft Toxicological Review of Trichloroacetic Acid provides scientific support and rationale for the hazard identification and dose-response assessment pertaining to chronic exposure to trichloroacetic acid. Trichloroacetic acid is used as an antiseptic, skin peeling agent, and chemical intermediate to produce a variety of organic chemicals. Trichloroacetic acid is also used industrially as an etching and pickling agent for surface treatment of metals and as a solvent in the plastics industry. Trichloroacetic acid is formed from organic materials during water chlorination.
This assessment contains the derivation of a chronic reference dose and cancer oral slope factor.
|1996||EPA posted the IRIS assessment for trichloroacetic acid on the database (cancer assessment only).|
|2004||EPA started IRIS reassessment of trichloroacetic acid cancer assessment and assessment of noncancer endpoints.|
|Sep 2009||EPA released an External Reviewer Draft for public comment and review.|
Following external peer review of the Toxicological Review of Trichloroacetic Acid (TCA) , the assessment will be revised, to respond to external peer review and public comments, will undergo a final EPA internal review and a review by and science discussion with other federal agencies and White House offices, and will be posted to the IRIS database.
