Exposure and Human Health Reassessment of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD) and Related Compounds National Academy Sciences (NAS) Review Draft
On October 15, 2004, the EPA transmitted to the National Academy of Sciences (NAS) the NAS Review Draft of EPA's Exposure and Human Health Reassessment of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD) and Related Compounds, in preparation for the first meeting of the NAS panel scheduled for November 22 and 23, 2004, in Washington, DC. For detailed information on the NAS's dioxin review activity, titled "Review of EPA's Assessment of the Health Implications of Exposure to Dioxins," please visit the NAS website at http://www.nas.edu . This will bring you to a description of the project, a list of the provisional panel, and information about the upcoming meeting.

IRIS Literature Screen Verification
The IRIS Program is beginning to add statements to certain existing IRIS Summaries confirming that the health effects information upon which the assessment was based is still current. This is to follow up on our February 9, 2004 FR notice (69 FR 5971) announcing the annual IRIS agenda. In that notice, EPA announced that we would use findings from our recent IRIS literature screening project (the results of which were added to IRIS in 2003) as the basis for a systematic update of the IRIS database. We explained that we would begin performing a more in-depth review of the extant health literature to confirm results from the literature screen. For those chemical substances confirmed to be without new health effects information likely to change an existing assessment, we stated that we would update IRIS Summaries to indicate this finding. Also, in the FR notice we sought submission of scientific information from the public to confirm the results of the literature screen review. The first 12 confirmatory statements have been added to IRIS Summaries for Barium cyanide, Butylphthalyl butylgylcolate, 1,4-Dibromobenzene, 2,3-Dichloropropanol, Ethylphthalyl ethylglycolate, Methyl chlorocarbonate, Selenourea, Silver cyanide, 1,1,2-Trichloropropane, Vernam, Cyanogen bromide, and 1,2,4-Tribromobenzene. This will be an on-going project.

External Peer Review Panel Meeting on IRIS Toxicological Review and Summary Documents for Naphthalene
The U.S. EPA is announcing that an external peer review panel meeting to review the inhalation cancer assessment and selected text in the external review draft document entitled, "Toxicological Review of Naphthalene: In Support of Summary Information on the Integrated Risk Information System (IRIS)"(NCEA-S-1707) was published in the Federal Register July 7, 2004 [FRL-7783-2; E-docket No.: ORD-2004-0007].
13 February 2004
Notice of peer review workshop of the external draft document titled, Neurotoxicity of Tetrachloroethylene. The draft document and charge to reviewers are available on the NCEA Web site. The workshop will be held on February 25, 2004. Click here to view the Federal Register notice.
09 February 2004
EPA's 2004 IRIS agenda and request for information was published in the Federal Register on February 9, 2004 [69 FR 5971]. Click here to view the Federal Register notice.
22 December 2003
A new summary for 2-Methylnaphthalene and accompanying Toxicological Review have been added to the IRIS Web site.
3 December 2003
An IRIS search has been updated -- Search by Evidence for Human Carcinogenicity. The updated search allows allows IRIS users to search the IRIS database to identify substances by weight-of-evidence classifications established by EPA using the 1986, 1996, and 1999 Guidelines for Carcinogen Risk Assessment. These guidelines reflect the evolution of the science in this area and the corresponding evolution of the Agency's approach to characterizing weight-of-evidence for human carcinogenicity. To view the search, please go to the IRIS Search page.
