Regulatory standards are already on the books at the the U.S. Environmental Protection Agency (EPA) to address health risks posed by inhaling tiny particles from smoke, vehicle exhaust, and other sources. At the same time, Congress and EPA have initiated a multimillion dollar research effort to better understand the sources of these airborne particles, the levels of exposure to people, and the ways that these particles cause damage. To provide independent guidance to the EPA, Congress asked the National Research Council to study the relevant issues. The result is a series of four reports on the particulate-matter research program. The first two books offered a conceptual framework for a national research program, identified the 10 most critical research needs, and described the recommended timing and estimated costs of such research. This, the third volume, begins the task of assessing the progress made in implementing the research program. The National Research Council ultimately concludes that the ongoing program is appropriately addressing many of the key uncertainties. However, it also identifies a number of critical specific subjects that should be given greater attention. Research Priorities for Airborne Particulate Matter focuses on the most current and planned research projects with an eye toward the fourth and final report, which will contain an updated assessment.

Chapters: historical overview; persistent toxic substances; pathways of exposure; a review of the Great Lakes (GL) human health literature; human health studies outside of the Great Lakes -- exposure to similar persistent toxic substances; limitations of human health studies; characterization of exposure and determination of the profiles and levels in human biologic tissues and fluids; identification of sensitive and specific human reproductive end points; determination of the short- and long-term risk(s) of adverse health effects in the children of exposed parents; and establishment of registries &/or surveillance cohorts in the GL.
