Project at a Glance

Title: Proceedings of the third colloquium on particulate air pollution and human health.

Principal Investigator / Author(s): Phalen, Robert

Contractor: UC Irvine

Contract Number: 98-332

Research Program Area: Health & Exposure

Topic Areas: Ambient Air Quality Stds, Health Effects of Air Pollution


Research on human exposure to ambient air particulate matter (PM) reported on at the Third PM Colloquium indicates that the field is now moving beyond descriptive reports that focussed largely on gravimetric concentrations of PM in ambient air and in other microenvironments, and their associations with indices of short-term changes in rates of mortality and morbidity. There is now a welcome shift in emphasis toward a more detailed analysis of PM exposures and dosimetry in terms of size-segregated PM fractions (PM10, PM2.5 and ultrafines) and their chemical constituents, as well as toward biological response measures. Such responses shed light on the underlying mechanisms that account for both short-and long term responses to ambient air PM and copollutants on the respiratory tract, the cardiovascular system, and immune function. Through both the formal presentations of research findings and the opportunities provided for more informal discussions of mutual interests, this Third Colloquium has enhanced opportunities for collaborative research that may be able to clarify the chain of events leading from pollution in the ambient air to adverse impacts on health and longevity.
