Summary/Accomplishments (Outputs/Outcomes):
I. Introduction
The rationale for this project is based on the conclusion that “[t]he diversity of PM characteristics and the array of possible health effects define a potentially large and complex matrix for investigation; in fact different features of particles might be relevant to different health outcomes” (NRC 2004) As a result we proposed to assess the specific chemical components and physical characteristics of particulate matter (PM) from samples taken in different areas of the country. These locations have been selected based on a gradient of estimated risks to health. Specifically, we proposed to develop a new method for collecting bulk PM for use in biological assays; to develop a portable system for the characterization of chemical and physical properties of ambient PM; and to identify specific regional differences in PM characteristics that may contribute to differential biological responses in in vitro and in vivo bioassay systems. This report will describe activities carried out by Project 2 (PI.Patrick Breysse) and the PM Characterization, Sampling and Analysis Core (PI Alison Geyh) since funding, giving emphasis to progress during the past year. The overall goal of developing a PM monitoring and collection approach and then deploying it at the sites identified through the Project 1 analyses has been accomplished.
