Report of the Particulate Matter Research Strategies Workshop, Park City, Utah, April 29–30, 1996

Abstract An informal one-and-a-half-day workshop devoted to research needs on the health effects of airborne particulate matter (PM) was held in Park City, Utah, on April 29 and 30, 1996, in conjunction with the Second Colloquium on Particulate Air Pollution and Health at Park City, Utah, on May 1–3, 1996. The objective of the workshop was to prepare a holistic assessment of knowledge gaps and research opportunities for presentation at the penultimate session of the colloquium. The workshop reviewed the research progress made since the first PM colloquium (Irvine, California, January 1994) and the findings of recent major reviews of the PM literature by the World Health Organization-European Region, the U.K. Health Department, the National Institute of Public Health in the Netherlands, and the U.S. Environmental Protection Agency.
