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 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.
