Beginning in 1997, EPA accelerated its investigations of fine particulate matter (PM2.5) to improve understanding of the potential health effects of the small particles in the outside air and to find ways to reduce risks from the air pollutant. Research has confirmed the links between exposure to PM2.5 and increases in respiratory health problems, hospitalizations and premature death. EPA's PM research has also affirmed the need for air quality standards to reduce PM in the air to protect human health.

A report entitled, "Particulate Matter Research Program: Five Years of Progress" (PDF, 208 p.p., 4.6 MB) highlights early results of EPA's substantial investment in particulate matter research by EPA scientists and grantees from universities and other research institutions across the country. The report also includes an in-depth examination of the health effects, exposure and prevention or mitigation of PM2.5. Below are some of the significant PM2.5 research findings to date:

EPA's Tools for Clean Air - even as new scientific information is being developed, EPA is moving forward with an aggressive regulatory program to control PM2.5. (PDF, 2 p.p., 745 KB)
EPA Chief Scientist Paul Gilman: What Have We Learned About PM Since 1997? (PDF, 30 p.p., 4.1 MB) - This presentation highlights the research conducted and funded by EPA Research and Development’s particulate matter (PM) research program since 1997 and provides a status report on what we know about PM and insights into what we need to know as we move into the future.

EPA continues to build its PM research program to provide further scientific information needed to ensure that the populations most vulnerable to the effects of PM will be protected and that air quality standards are implemented in the most effective ways possible.
