【 摘 要 】

This report describes the technical progress made on the Pittsburgh Air Quality Study (PAQS) during the period of March 2003 through August 2003. Significant progress was made this project period on the source characterization, source apportionment, and deterministic modeling activities. Major accomplishments included: Development of an emission profile for an integrated coke production facility and simulations using PMCAMx for a two week period during July 2001. The emissions from the coke facility are dominated by carbonaceous compounds. Forty seven percent of the organic carbon mass was identified on a compound level basis. Polycyclic aromatic hydrocarbons were the dominant organic compound class in the coke emissions. Initial comparisons with the data collected in Pittsburgh suggest good agreement between the model predictions and observations. Single particle composition data appear useful for identifying primary sources. An example of this unique approach is illustrated using the Fe and Ce particle class with appear associated with steel production.
