Workshops to Support Development of EPA's IRIS Toxicological Reviews

Project Scope:

An ad hoc committee will organize up to two workshops on topics pertinent to the development of draft toxicological reviews by the U.S. Environmental Protection Agency's Integrated Risk Information System (IRIS) program.  The workshops will be designed to assist EPA with increasing quality, transparency, and confidence in its assessments by addressing scientific issues related to systematic review, hazard identification, and dose-response analysis.  Topics could include the following:

  • approaches to planning and performing evidence identification,
  • methods for evaluating individual studies and bodies of evidence,
  • approaches to synthesizing and integrating evidence to reach hazard conclusions,
  • development and application of specialized tools for systematic review,
  • considerations in study selection for developing toxicity values, and
  • research on quantitative analyses for evidence integration and dose-response analyses.

Event Type :  

Description :   

The National Academies of Sciences, Engineering, and Medicine will be holding a workshop on current state-of-the-art in performing systematic reviews of mechanistic data to support chemical assessments. Topic areas include:

-- Approaches and tools to search and screen the literature for mechanistic data,
-- Approaches to evaluating the validity of mechanistic studies,
-- Methods for assimilating and using mechanistic information to support evidence synthesis and integration, and
-- Practical experience with implementing systematic reviews of mechanistic evidence into human health assessments.

The objective of the workshop is to explore relevant strategies and tools that are being developed and used across the systematic review and risk assessment communities to assist the US Environmental Protection Agency with developing guidance on performing systematic reviews of mechanistic data to support the chemical assessments in its Integrated Risk Information System program. A poster session will accompany the workshop that will have examples demonstrating the application of systematic review approaches to mechanistic data.

Poster Session

To accompany the workshop, we are seeking examples of the application of systematic review approaches for mechanistic data that are relevant to chemical assessments. Poster presentations considered for acceptance will focus on the specific application of strategies and tools, preferably through case study application, that are anchored to one of the four topic areas described above.

Submission and Selection Process
-- Deadline for submission is September 30, 2018.
-- Poster abstract submission is open to the public.
-- Abstracts will be reviewed and selected by the workshop organizing committee.
-- All travel costs are the responsibility of the presenters.
