IRIS Bimonthly Public Science Meeting (October 2014)

UPDATE: Thanks for your participation in our October Meeting, presentations are now available under the meeting materials tab.

EPA hosted a Bimonthly IRIS public meeting to provide an opportunity for the public to give input and participate in an open discussion regarding preliminary materials that were prepared for IRIS chemicals prior to the development of the draft assessment. This included the following chemicals:

Note: The Cr(VI) materials released for this meeting are the second set of preliminary materials released on this chemical. The materials include updated information on the literature search and screening strategy, approaches for the selection of human studies of Cr(VI) for hazard identification, presentation of critical human studies in evidence tables, and a preliminary summary of toxicokinetic and mechanistic studies pertinent to the assessment of Cr(VI). The first set of preliminary materials released in April 2014, Preliminary Materials for the Integrated Risk Information System (IRIS) Toxicological Review of Hexavalent Chromium Part 1: Experimental Animal Studies, presented the planning and scoping summary, problem formulation information, and evidence tables for experimental animal data for the health effects of Cr(VI).

Meeting Objective:

The objective of this public meeting was 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 was 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 was held on October 29-30 , 2014 from 9:00am - 5:00 pm Eastern Time.


The meeting was held at the EPA Conference Center at 2777 South Crystal Drive, Arlington, Virginia 22202. The meeting was also streamed by webinar/teleconference for remote participants.
