EPA RELEASES RISK ESTIMATES FOR 33-TOXIC AIR POLLUTANTS

EPA is making available the updated analysis of health risk estimates for 33-toxic air pollutants nationwide. Toxic air pollutants are known to or suspected of causing cancer or other serious health problems, such as birth defects. As part of this technical assessment, emissions and concentration estimates of the toxic air pollutants were publicly made available in August 2000. EPA submitted the national-scale assessment for scientific peer review in 2001. The national-scale assessment is based on 1996 emissions data because emissions inventories from that year are the most complete and available to date. The 1996 data do not reflect pollution reductions that have taken effect since 1996, including those from federal, state and local regulations or from industry initiatives or facility closures. By identifying the air toxics that may pose the greatest risk in urban areas, this assessment will help regulatory agencies set priorities for collecting additional data to help assess risk. This national assessment was not designed to compare risks at local levels. The complete results of the technical analysis, as well as background and supporting information are posted at: https://www.epa.gov/ttn/atw/nata .
EPA, AMERICAN CHEMISTRY COUNCIL TO COORDINATE RESEARCH ON EFFECTS OF CHEMICALS ON DEVELOPING IMMUNE SYSTEMS IN HUMANS AND WILDLIFE

EPA and the American Chemistry Council (ACC) will coordinate on two multi-year Cooperative Research and Development Agreements (CRADAs) to better understand the potential effects of chemicals on fetal and childhood immune system development and the potential impacts of endocrine-active chemicals on wildlife populations. The first area of research seeks to understand the mode of action of selected chemicals on the developing immune system of laboratory animals, thereby enabling the development of better test methods. To date, no specific testing approach has been established to assess the potential impact of environmental contaminants to children’s developing immune system. The results from this research will provide relevant scientific information that can be applied to the assessment of risks for children. The second project applies a rapidly expanding approach to molecular-level investigations called “gene-array technology.” This technology will enable scientists to evaluate the ecological effects of endocrine-active chemicals in amphibian and fish models. The involvement of the ACC and the chemical industry in these two research projects is supported through their “Long-Range Research Initiative,” which since 1999 has committed $25 million a year to increase knowledge of the potential impact that chemicals may have on human and wildlife populations and the environment.
