Abstract  

Tracking contributions of vehicular emissions to urban fine particulate matter (PM2.5) air pollution has been challenging. My research involves field measurements of PM2.5 chemical compositions using both online and offline techniques at multiple air quality monitoring sites in Hong Kong. The data are analyzed with multiple approaches (EC-tracer method, CMB and PMF) to constrain the source contribution estimation for vehicular emissions.
