The EPA in the Friday, Dec. 12, 2010, Federal Register announced the availability of literature searches for four IRIS assessments:

• acetaldehyde (CAS No. 75-07-0)
• hexachlorobutadiene (CAS No. 87-68-3)
• hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) (CAS No. 121-82-4), and
• naphthalene (CAS No. 91-20-3)

The agency is requesting scientific information on health effects that may result from exposure to these chemical substances.

The EPA is soliciting public involvement in assessments on the IRIS agenda, including new assessments starting in 2011. The agency hoping there are some unpublished studies or other primary technical sources that are not available through open literature. The public may submit information on any chemical substance at any time.

The above-listed literature searches are available on the EPA's IRIS website under "IRIS Agenda and Literature Searches.''
