Committee on Research Priorities for Airborne Particulate Matter
******
The U.S. Environmental Protection Agency recently issued new air quality standards for particulate matter, a broad class of chemically diverse substances that originate from industrial manufacturing processes, automobile exhaust, fossil fuel combustion, naturally occurring dusts, and a variety of other sources. The new standards for the first time target air particles smaller than 2.5 microns in diameter. But scientific knowledge is limited on which types of particles are harmful, how the harmful effects are produced, and the levels of particulate matter to which people are exposed. This report, Research Priorities for Airborne Particulate Matter -- Interim Report, identifies the most important research priorities for improving the understanding of airborne particulate matter and its health effects.
A congressional briefing for Members and/or Staff was held on Tuesday, April 21, 1998. The report was publicly released on March 31, 1998
