IRIS Public Science Meeting (June 2014)

UPDATE: Thanks for the great turn-out and response to our June 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 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.

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 June 25-27 , 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.
