EPA hosted an IRIS public meeting on January 8-9, 2013, to provide an opportunity for the public to give input and participate in an open discussion regarding scoping and problem formulation materials that were prepared for IRIS chemical, inorganic arsenic, prior to the development of the draft assessment.

Impact/Purpose:

EPA is updating the health assessment for inorganic arsenic for the Integrated Risk Information System (IRIS). The outcome of this project will be a Toxicological Review and IRIS Summary of inorganic arsenic (noncancer) that will be entered on the IRIS database. IRIS is an EPA database containing Agency scientific positions on potential adverse human health effects that may result from chronic (or lifetime) exposure to chemicals in the environment. IRIS contains chemical-specific summaries of qualitative and quantitative health information to evaluate potential public health risks associated with exposure assessment information to evaluate potential public health risks associated with environmental contaminants. The IRIS database is relied on for the development of risk assessments, site-specific environmental decisions, and rule making.

Description:

In November 2012, EPA released scoping and problem formulation materials for the IRIS assessment of inorganic arsenic for public comment and discussion. The scoping information was based on input from EPA's program and regional offices and was provided for informational purposes.

During problem formulation, the IRIS Program was looking for input from the scientific community and the general public as it frames the specific scientific questions for the systematic reviews that it will conduct to develop the assessments.
