Intra-urban spatial variability of PM_2.5-bound carbonaceous components.

ABSTRACT: The Denver Aerosol Sources and Health (DASH) study was designed to evaluate associations between PM_2.5 species and sources and adverse human health effects. The DASH study generated a five-year (2003-2007) time series of daily speciated PM_2.5 concentration measurements from a single, special-purpose monitoring site in Denver, CO. To evaluate the ability of this site to adequately represent the short term temporal variability of PM_2.5 concentrations in the five county Denver metropolitan area, a one year supplemental set of PM_2.5 samples was collected every sixth day at the original DASH monitoring site and concurrently at three additional sites. Two of the four sites, including the original DASH site, were located in residential areas at least 1.
