Summary and findings of the EPA and CDC symposium on air pollution exposure and health

The U. S. Environmental Protection Agency (EPA) and the U. S. Centers for Disease Control (CDC) co-organized a symposium on "Air Pollution Exposure and Health" at Research Triangle Park, North Carolina on September 19-20, 2006. The symposium brought together health and environmental scientists to discuss the state of the science and the cross-jurisdictional and methodological challenges in conducting air pollution epidemiology, environmental public health tracking and accountability research. The symposium was held over 2 days and consisted of technical presentations and breakout group discussions on each of the three principal themes of this meeting: (1) monitoring and exposure modeling information, (2) health effects data and (3) linkage of air quality and health data for research, tracking and accountability. This paper summarizes the symposium presentations and the conclusions and recommendations developed during the meeting. The accompanying two papers, which appear in this issue of the Journal, provide more in-depth discussion of issues pertinent to obtaining and analyzing air pollution exposure and health information. The symposium succeeded in identifying areas where there are critical gaps of knowledge in existing air pollution exposure and health information and in discovering institutional or programmatic barriers, which impede accessing and linking disparate data sets. Several suggestions and recommendations emerged from this meeting, directed toward (1) improving the utility of air monitoring data for exposure quanti. cation, (2) improving access to and the quality of health data, (3) studying emerging air quality and health issues, (4) exploring improved or novel methods for linking data and (5) developing partnerships, building capacity and facilitating interdisciplinary communication. The meeting was successful in promoting an interdisciplinary dialogue around these issues and in formulating strategies to support these recommended activities. Finally, this symposium subsequently led to strengthening and initiating new partnerships or interactions between the EPA, CDC, States, academia and the research community at large.
