Abstract In order to clarify the characteristics of the emission and dispersion of polycyclic aromatic hydrocarbons (PAHs) from vehicle transportation activities, the atmospheric concentration of PAHs was measured at roadside of a heavy traffic road. The samplings were conducted in summer (July and August) and winter (November, December, and January). Atmospheric particulate matters (fine particle, 0.6- 7 pm; coarse particl, over 7 pm) and deposited particulate matters were collected, and their PAH concentration was measured. From the vehicle traffic data and emission data, the emission load and dispersion profile were estimated. From the analysis, source partitioning of each particulate m
