US EPA

This presentation will describe the following items: important epidemiologic data establishing the need for new particulate matter standards, the size distribution of suspended particulate matter, epidemiologic data demonstrating the need for a fine particle standard, indicator and levels for the new fine particle standards, problems in measurement of PM2.5 caused by the semivolatile components of fine particles, the contribution of ambient particles to indoor pollution, and EPA's role of research and public awareness but not control of indoor air pollution. The presentation will then discuss the implications of the new fine particle standards for filter manufacturers including increased concern with removal of nuclei and accumulation mode particles; increased interest in air cleaning for automobile interiors, homes, and institutional buildings, especially for the sick or elderly; and the need for filters that will remove the gas phase portion of semivolatile particulate matter and other gas phase pollutants.
