Webinars to Obtain Peer Input on Draft Materials for the
Integrated Science Assessment (ISA) for Nitrogen Oxides (NOx) and
Sulfur Oxides (SOx): Ecological Criteria

This series of three online-only webinars is designed to solicit input from subject matter experts on the scope and content of draft sections of the ISA on discipline-specific topics related to ambient concentrations, exposure, and ecological effects of NOx and SOx. Expert reviewers will represent a wide range of external experts as well as EPA staff with various areas of expertise, and will highlight significant new and emerging research and make recommendations to the Agency regarding the design and scope of this review. These webinar discussions will be considered as the Agency finalizes the first External Review Draft ISA.
