(08/22/03) EPA will begin health risk assessments for six new chemicals through the Agency’s Integrated Risk Information System (IRIS) program, and will accept nominations from the public for additional chemicals to be assessed. IRIS, an important information resource, provides EPA consensus opinions on the possible adverse human health effects from exposure to chemical substances in the environment. The chemicals selected by EPA for review are: acrylonitrile, beryllium (cancer update), n-hexane, methylene chloride (dichloromethane), trichloroacetic acid, and 1,2,3-trichloropropane. For each chemical in IRIS, information is provided on hazard identification and dose-response evaluation, the first two critical steps of the risk assessment process. IRIS currently contains information on more than 500 chemical substances and is considered a major source of health risk data for U.S. scientists. In past years, chemicals were nominated for review exclusively by EPA program and regional offices. This year, for the second time, as part of EPA’s commitment to increase citizen involvement in the Agency’s work on public health protection, the call for nominations will be extended to the public. Public nominations will be due 60 days after the publication of the Federal Register notice, and may be submitted on-line at: , by e-mail or U.S. postal mail. Detailed information on submission requirements can be found in the Federal Register or on the IRIS Web site at: .
