 |  |  | | 2,3,7,8-Tetrachlorodibenzo-p-dioxin | 2,3,7,8-Tetrachlorodibenzofuran | 3,3',4,4',5,5'-Hexachlorobiphenyl |  | |  | Dioxin Reassessment (NAS Review Draft) | | In October 2004, the EPA's draft dioxin reassessment was delivered to the National Academy of Sciences (NAS) for review. That draft document, as well as background information, is available here. | | THIS DOCUMENT IS A DRAFT FOR REVIEW PURPOSES ONLY AND DOES NOT CONSTITUTE U.S. ENVIRONMENTAL PROTECTION AGENCY POLICY. It has been provided for review to the National Academy of Sciences (NAS). While the NAS review is being conducted and until a final agency assessment has been released, the draft dioxin reassessment (NAS Review Draft or other draft versions) remains draft, does not represent a final position, and is not intended to serve as the basis or rationale for regulatory and other policy action. However, EPA will continue its work to reduce human exposure to dioxin. While the NAS review is underway and no final reassessment has been issued, in meeting their regulatory responsibilities, the agency will continue its current practice of utilizing the best available data that meet the EPA Information Quality Guidelines and the government-wide Information Quality Guidelines issued by OMB. The Agency will consider all such data and associated uncertainty to determine the strength of the evidence in proposing regulatory actions related to dioxin and dioxin-like compounds. | | | Dioxin: Frequently Asked Questions (FAQs) | | These FAQs provide information about dioxins. Topic areas include: general information, overview of the EPA dioxin report, food safety, and risk assessment. They were prepared by the Interagency Working Group on Dioxin. | | | Dioxin Exposure Initiative (DEI) | | In 1994, the EPA embarked upon a research program to further evaluate the exposure of Americans to this class of compounds. This program is called 'The Dioxin Exposure Initiative', abbreviated the DEI. The DEI is a research program jointly funded and managed by the Office of Research and Development and the Office of Prevention, Pesticides, and Toxic Substances. Further information on the DEI is available here. | | | Database of Sources of Environmental Releases of Dioxin-like Compounds in the United States (EPA/600/C-01/012, March, 2001) | | The purpose of this database is to document congener-specific emissions and environmental releases of polychlorinated dibenzo-para-dioxins (CDDs) and polychlorinated dibenzofurans (CDFs) from known source activities in the U.S. Included within the database are facility-specific emissions for a variety of CDD/CDF sources, and congener-specific I-TEQ and WHODF-TEQ emission factors. The database contains information that can be used to track CDD/CDF emissions over time; develop and compare congener-specific and homologue profiles for source categories; and to develop congener-specific emission factors that can then be used to undertake an emissions inventory of sources. The database is associated with two reference years: 1995 and 1987. | | | EPA Analytical Methods | | The published EPA analytical method for analysis of dioxin and related compounds is Method 1613. Information on how to obtain copies of the EPA analytical methods for dioxins and other contaminants is available here. | | | EPA Regulations | | | Information on EPA regulations and related activities is available here. |
