Review of EPA’s IRIS Assessment Handbook


Project Scope:

An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will evaluate EPA's ORD [Office of Research and Development] Staff Handbook for Developing IRIS Assessments (or IRIS Handbook).  The committee will evaluate the operating procedures for developing hazard and dose-response assessments of potential human health effects from exposure to environmental contaminants.  The procedures and considerations for operationalizing the principles of systematic review within these human health assessments will be evaluated.  Consideration will also be given to the guidance on determining the scope of the IRIS assessments (e.g., health outcomes, routes of exposure); evidence integration; extrapolation techniques (e.g., physiologically based pharmacokinetic models); dose-response analyses (e.g., statistical methods); and characterization of uncertainties.
