2005 PM BOSC Review
Note: EPA no longer updates this information, but it may be useful as a reference or resource.
EPA's Particulate Matter (PM) Research Program was reviewed by a Board of Scientific Counselors (BOSC) in Spring 2005. The objective of the review was to evaluate the PM program's quality, relevance, performance, and scientific leadership. EPA relies on such evaluations to help ensure that its research programs are making significant progress and that the outcomes of its research are used to support sound environmental decision making.

By 1996, considerable evidence had accumulated suggesting that exposures to ambient particulate matter (PM) at or near the level of the then current National Ambient Air Quality Standard (NAAQS) were eliciting significant human health effects in the U.S. population. This evidence led to the promulgation of a new PM NAAQS in 1997, including a standard for PM smaller than 2.5 µm in aerodynamic diameter (PM
2.5).

Air quality management and "implementation" research are terms used in this review to categorize research designed to better understand atmospheric concentrations of PM-Ozone, sources that contribute to these levels, and approaches to reduce emissions. The principal focus of the discussion that follows is on PM and its co-pollutants.
THEME 3. Source to Health Outcomes

It is tempting to ask why "
Source to Health Outcomes" is a topic at all, as it would seem obvious that the entire PM research program is intended to address this very issue. But even though that is indeed the case, our tendency as scientists is to reduce problems to their fundamental components. The structure of our organizations, our training, and more immediately, the recommendations of the NRC Committee on Research Priorities for Airborne Particulate Matter all reinforce our inclination to take a reductionist approach to addressing PM.
