  1. - Welcome to CMAS -Air Quality Science: An Essential Ingredient for Air Pollution Health Studies Session Dan Costa, Sc.D. DABT National Program Director for Air Research Office of Research & Development CMAS 2010 October 13, 20110

  2. Why this Session? • Advances in air pollution health epidemiology revolutionized the way health risks are assessed • With established “biologic plausibility” the epi community has pushed our understanding of AP risks to levels of detail not thought possible • Exposure has always been a “soft spot” • Exposure ~ fx[Ambient air concentration] • Air quality modeling has also advanced: • ever-decreasing grid size • sophistication of atmospheric met/phys/chem • expansion to multi-pollutant dimensions

  3. Goals of the Session • Overarching Questions: • How do we bring Epi-AQ communities together? • Is the science ready to move into this new territory? • Promote feedback from the health community to the air quality modeling community • Discuss key elements in air quality characterization • Spatial • Temporal • Compositional • Establish an self-propagating dialogue

  4. Overview of the Session Morning • Get perspective on health studies • Get perspective on air quality characterization techniques Afternoon • Get perspective on applications of air quality modeling and statistical approaches • Discussion of how to lead the science forward

  5. Challenge - Diversity of Applications Prospective vs Retrospective Studies

  6. Tiered Exposure Metrics Hypothesis – Refined exposure estimates will provide greater power to detect epidemiologic associations
