 note = {[Abstract]Polycyclic aromatic hydrocarbons (PAHs) are considered to be air pollutants and human carcinogenic substances. In this study, we measured PAHs in the aerosol samples (from September 2005 to August 2006) and also gaseous PAHs (from November 2005 to October 2006) for one year in the suburbs of Higashi-Hiroshima, Japan. The aerosols were classified into nine stages according to the particle diameter. The average concentration of PAHs in the aerosol was 2.93 ng/m3. The concentrations of PAHs in aerosol were higher in the fine particles than the coarse particles throughout the year and also higher in winter than in summer. The average concentration of gaseous PAHs was 50.6 ng/m3. Low molecular weights of PAHs were mainly found as gaseous components, and higher molecular weight of PAHs as particulate components. Middle molecular weights of PAHs coexisted as both gaseous and particulate components and the contents of particulate components were higher in winter than in summer. Molecular diagnostic ratios were examined to identify possible PAHs emission sources, suggesting vehicular emissions as a major source of particulate PAHs., application/pdf},
