Abstract: Airborne Particulate Matter (PM) was collected in a cross-river road tunnel using portable air samplers and a cascade impactor. Sixteen EPA priority Polycyclic Aromatic Hydrocarbons (PAH) in the PM were quantified by gas chromatography/mass spectrometry. Profiles and diagnostic ratios of PAHs were investigated, and size distribution of PM mass and PAHs were discussed. High concentrations of PM2.5 (2.30 ± 0.86 mg m−3) and total 16 PAHs in PM2.5 (841.7 ± 116.9 ng m−3) were observed. The profiles of individual PAH and diagnostic ratios of Ant/(Ant + Phe), Flt/(Flt + Pyr), BaA/(BaA + Chr), IcdP/(IcdP + BghiP) represented typical emissions from motor vehicles. Size distribution patterns and correlation between mass median aerodynamic diameters and log pL0 reflected the co-influence of vehicular emissions and volatilisation-condensation processes on the size partitioning of PM mass and individual PAHs in the tunnel.
