Abstract
The source and transport pathway of 16 EPA priority PAHs in the road dusts collected from Shanghai urban area in winter and summer were analyzed. Statistics analysis and some diagnostic ratios were used for source identification and the contribution rates of main sources were also calculated. Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% (winter) and 64.93% and 14.11% (summer) respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion. In addition, local pollution sources were the main sources.
