IRIS Public Science Meeting (June 2014)
NOTICE: All preliminary materials, agenda, and a list of scientific issues to be discussed at the meeting, are available on the web site.
EPA has released the preliminary materials associated with the IRIS assessments of inorganic arsenic (iAs) and hexavalent chromium (Cr(VI)) for public comment and discussion. The scientific issues to be discussed at the meeting have been posted under "Meeting Materials" and meeting registration is now open.
IRIS bimonthly public science meetings allow the public the opportunity to provide input and participate in discussions about preliminary assessment materials and draft IRIS assessments.
At the June meeting, materials related to the following chemicals will be discussed:
- Hexavalent Chromium (Cr(VI))
- Inorganic Arsenic (iAs)
Note: The preliminary materials for inorganic arsenic and hexavalent chromium present study information using two very different approaches with varying levels of detail. Inorganic arsenic is exploring the use of a modification of the draft approach developed by the NTP’s Office of Health Assessment and Translation, while hexavalent chromium is using modified approaches under development by the IRIS Program. The IRIS Program intends to evaluate how well each approach facilitates subsequent assessment development, promotes constructive public discussion, and makes efficient use of program resources.
UPDATE: EPA has released the preliminary materials associated with the IRIS assessments of hexavalent chromium (Cr(VI)) and inorganic arsenic (iAs) for public comment and discussion during the June Public Science Meeting. The preliminary materials include information about: the uses and occurrence of these chemicals in the environment; why EPA is developing the assessments; the approaches for selecting primary studies to be included in the evidence tables; and the approach for evaluating methodological features of studies that will be important for the subsequent development of the draft IRIS assessments. In addition, the IRIS Program is using a new meeting format intended to promote public discussion. This format is designed to explore varying scientific perspectives from a diverse set of stakeholders on key science issues for the assessments in question. Stakeholders may also suggest additional key science issues to discuss at the meeting.
The objective of this public meeting is to obtain input from stakeholders and the public on the studies and data that will be used in the assessments that are under development. Specifically, EPA is seeking input on preliminary materials including draft literature searches and associated search and screening strategies, the approach for selecting primary studies to be included in the evidence tables, the approach for evaluating methodological features of studies, evidence tables, and exposure-response arrays prior to the development of the IRIS assessments.
The meeting is scheduled for June 25-27 , 2014.
The meeting will be held in the EPA Conference Center at 2777 South Crystal Drive, Arlington, Virginia 22202. The meeting will also be available by webinar/teleconference.
