EPA is announcing that Versar, Inc., an EPA contractor for external scientific peer review, will convene an independent panel of experts and organize and conduct an external peer-review workshop to review the external review draft document titled, “Toxicological Review of Trichloroacetic Acid: In Support of Summary Information on the Integrated Risk Information System (IRIS)” (EPA/635/R-09/003A). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development. EPA previously announced the 60-day public comment period (ending November 23, 2009) for the draft document in the Federal Register on September 24, 2009 (74 FR 48735). EPA will consider public comments and recommendations from the expert panel workshop as EPA finalizes the draft document.

Information About IRIS

IRIS is a database that contains potential adverse human health effects information that may result from chronic (or lifetime) exposure to specific chemical substances found in the environment. The database (available on the Internet at http://www.epa.gov/​iris) contains qualitative and quantitative health effects information for more than 540 chemical substances that may be used to support the first two steps (hazard identification and dose-response evaluation) of a risk assessment process. When supported by available data, the database provides oral reference doses (RfDs) and inhalation reference concentrations (RfCs) for chronic health effects, and oral slope factors and inhalation unit risks for carcinogenic effects. Combined with specific exposure information, government and private entities can use IRIS data to help characterize public health risks of chemical substances in a site-specific situation and thereby support risk management decisions designed to protect public health.
