  1. Working Group on Effects, 29th Session, 22-24 September 2010 Task Force on Health:Results - common issues ECE/EB.AIR/WG1/2010/11 Michal Krzyzanowski TFH Chair WHO/Europe, European Centre for Environment and Health, Bonn http://www.euro.who.int/air

  2. Accessibility of health-relevant AQ data • Several web-based systems displaying current AQ data (cities, countries, international) – very useful in case of evaluation of regional pollution episodes • Different methods of data presentation; • No harmonized information on health relevance of air pollution

  3. Analyzing evidence on impacts of various air pollution management options on health • Contrast in exposure before / after intervention Limited contrast may make demonstration of the health benefits impossible due to limited power of health study. Consider evaluation of changes in emission / air quality / exposure first. • Studies of abrupt changes in emissions • Focus on interventions related to well defined source category • Consider possibility of “pooled” studies, based on the same intervention affecting various locations / populations • Develop an inventory / clearinghouse of interventions • Improve methodological approaches to the studies • Accountability assessment of long-term regulatory actions • Conduct retrospective assessment of AQ regulations • Plan in advance evaluation of future legislation (modeling; setting up long term study)

  4. Review of health effects modeling • Use GAINS to estimate population exposure under various scenarios; • Continue effects assessment based on PM2.5 (annual mean) and O3 (SOMO35); • Include cause-of-death assessment as sensitivity analysis ; • Continue using ACS risk estimates; • Consider the variability of exposure / impacts on a small geographical scale; • Convene a dedicated workshop to review HIA approaches.
