Meeting Materials for the NAS Meeting to Evaluate the Updated Problem Formulation and Systematic Review Protocol for the Inorganic Arsenic (Ias) IRIS Assessment Document (Jul 2019)
In July 2019, an NAS ad hoc committee will conduct a peer review of the revised scope of the assessment and determine whether the proposed methods are appropriate to synthesize the scientific evidence and develop conclusions. Given the size and complexity of the evidence base for this chemical, input on the scope of this assessment has been sought from the National Academy of Sciences, Engineering, and Medicine (NAS), EPA Program and Regional Offices, other federal agencies, and public stakeholders to help focus the objectives of the assessment and ensure it is transparently conducted. The Updated Problem Formulation and Protocol summarizes the Agency's need for the assessment and presents the refined focus based on problem formulation activities conducted since the last assessment plan released to the NAS in 2015.
