Analysis of particulate-matter dispersion near urban roadways. Final technical report

Technical Report ·
OSTI ID:7225522
The report focuses on the collection and statistical analysis of particulate emissions near urban roadways. Specifically, data was collected on particulate matter smaller than 2.5 microns (PM(sub 2.5)) on roadways near the University of Washington, Seattle, campus. PM(sub 2.5) was selected because of its high potential health risk. It is important to note that PM(sub 2.5) can be attributed almost entirely to the combustion process; existing road dust should not contribute significantly to subsequent PM(sub 2.5) measurements. The statistical analysis of the data indicated that the determinants of PM(sub 2.5) concentrations near urban roadways were a function of wind direction, number of cars, and number of buses. This report begins with a description of the study approach and data preparation and modelling approach. A statistical assessment of the results is then presented and, finally, the conclusions of the study are given. Appendices include descriptions of the air pollution equipment tests, graphs of test results, details of statistical results, and literature related to particulate matter emission modelling.
