Final Progress Review for EPA STAR Sources, Composition, and Health Effects of Coarse Particulate Matter

March 18, 2013
EPA at Research Triangle Park, NC
Building C, Auditorium C111 (A-c)


Previously, there has been a lack of published studies investigating the associations of mortality and morbidity with coarse particulate matter (PM10-2.5) and addressing the effects of different components or sources of these particles. The composition and toxicity of coarse PM likely vary significantly across locations with large differences between urban and rural regions because of a variety of different sources (e.g. pollen, endotoxin, road dust, agriculture, mining) and difficulties in estimating risks and exposure estimates.

In 2007, the National Center for Environmental Research awarded five STAR grants for research studies to improve understanding of the composition, sources, and health effects of urban and rural coarse PM, which includes particles in the size range from 2.5 to 10 micrometers in diameter. This meeting will include presentations and discussions of the final results from these STAR grantees and EPA scientists.

For more details on the STAR grants, see: Sources, Composition, and Health Effects of Coarse Particulate Matter.
