【 摘 要 】

A letter report issued by the Government Accountability Office with an abstract that begins "Over 100,000 chemicals, pollutants, and toxic substances are used in the United States and regulated by the Environmental Protection Agency (EPA). EPA uses risk assessment to determine the health risk from exposure to these substances, collectively referred to as contaminants. In the last 12 years, independent reviewers have examined this process and made recommendations for how it could be improved. GAO was asked to (1) identify the significant recommendations that have been made to improve human health risk assessment; (2) describe what EPA has done to modify its human health risk assessment process; (3) determine the effects these past modifications have had on the preparation of risk assessments; and (4) identify any additional actions experts believe EPA could take to improve its process, and the barriers it would face in doing so."
