January 30, 2015
EPA is announcing the availability of the Second External Review Draft of the Integrated Science Assessment for Oxides of Nitrogen - Health Criteria for public comment and independent peer review as announced in a January 30, 2015 Federal Register Notice.
January 15, 2015
Cover of Waters of the US Connectivity of Streams Final Report EPA announces the availability of the final report "Connectivity of Streams and Wetlands to Downstream Waters: A Review and Synthesis of the Scientific Evidence" in a January 15, 2015 Federal Register Notice. The purpose of this report is to summarize the current understanding about the connectivity and mechanisms by which streams and wetlands affect the physical, chemical, and biological integrity of downstream waters. In addition, EPA's Response to Peer Review Comments document was also posted.
December 23, 2014
EPA announces the availability of the final report, SUMMARY REPORT: State-of-the-Science Workshop on Chemically-Induced Mouse Lung Tumors: Applications to Human Health Assessments. EPA hosted a two-day, state-of-the-science workshop in January 2014, which covered a broad range of evidence from human, animal, and in vitro studies with a focus on specific chemicals (ethylbenzene, naphthalene, and styrene) that cause lung tumors in mice and are implicated in a proposed species-specific mode of action (MOA) based on metabolic and physiological susceptibility. The report is a brief summary of the proceedings of the workshop.
December 08, 2014
EPA announced that dibutyl phthalate (DBP) has been added to the agenda for the February 2015 Bimonthly Public Meeting. The preliminary materials for DBP will be released in mid-January. There are specific deadlines for DBP discussant registration and comments which are posted on the February 2015 IRIS Bimonthly Public Meeting web site.
November 28, 2014
EPA announced the availability of the draft report, Regional Monitoring Networks to Detect Climate Change Effects in Stream Ecosystems (External Review Draft) for a 30-day public review and comment period. Any comments received on the draft report within the next 60-days will be considered by EPA in their revisions. Comments should be in writing and must be received by EPA by December 29, 2014. [Federal Register Notice November 28, 2014]
November 21, 2014
EPA announced that they have canceled the December IRIS Bimonthly Public Science Meeting on BBP and DIBP and will instead discuss these chemicals at the February 25-26, 2015 meeting. EPA previously announced on October 15, 2014, an agreement with the National Academies' National Research Council (NRC) to arrange for independent experts input on the science underlying the development of IRIS assessments through participation in IRIS Bimonthly Public Science Meetings. These independent experts, speaking on their own behalf, will contribute to the scientific discussions of issues amongst EPA, stakeholders, and the public. The February meeting will be the first event where NRC identified experts will join the public discussion on preliminary assessment materials.
November 06, 2014
The IRIS Program announced that they have posted the schedule and dates for the 2015 IRIS Bimonthly Public Science Meetings. The specific dates are listed on the IRIS public meeting page and will include meeting materials before each meeting is announced on the IRIS home page.
October 15, 2014
In October, the IRIS Program announced that the bimonthly public science meetings will now be supplemented by scientific experts identified by the National Academies: National Research Council (NRC). These independent experts will provide valuable scientific input and broaden the range of perspectives represented at our public meetings. [IRIS Announcement October 15, 2014]
September 26, 2014
Cover of the Next Generation for Risk Assessment 2014 Final ReportEPA is announcing the release of the final report, Next Generation Risk Assessment: Incorporation of Recent Advances in Molecular, Computational, and Systems Biology. This report describes new approaches that are faster, less resource intensive, and more robust that can help address the challenges of assessing potential health hazards for large number of chemicals introduced into the environment and to evaluate their safety from the perspective of human health. This report describes how new molecular, computational and systems biology data and approaches (together called "NexGen") could better inform risk assessment. Learn more about the NexGen Program at http://epa.gov/risk/nexgen.
September 22, 2014
Cover of the Child-Specific Exposure Scenarios Examples Final ReportEPA announces the final report, Child-Specific Exposure Scenarios Examples. This report is intended to be a companion document to the Exposure Factors Handbook (U.S. EPA 2011). The example scenarios were compiled from questions and inquiries received from users of the Exposure Factors Handbook (EFH) on how to select data from the EFH to assess childhood exposures.
