Abstract
54 Road dust samples were collected in principal roads (n=37) and residential roads (n=17) nationwide in Japan from March 2010 to November 2012. Sixteen polycyclic aromatic hydrocarbons (PAHs) and ignition loss (IL) were determined. The total PAHs contents ranged from 62 to 6,325 ng g-1 with a geometric mean of 484 ng g-1. The IL ranged from 0.8-17% with a mean of 6%. The PAHs contents were correlated with the IL contents, and the IL contents were dependent on the population density. From the PAHs patterns analysis, the PAHs of road dust is considered to be majorly from the diesel emissions.
