Abstract

Gas and particle phase ambient concentrations polycyclic aromatic hydrocarbons (Sigma 13PAH) were determined at urban and suburban sites in Eskisehir and in a traffic-tunnel. Organic and elemental carbon (OC and EC) concentrations of total suspended particles (TSP) were also measured. Atmospheric Sigma 13PAH (gas+particle) concentrations measured at suburban sites was found to be lower than that of tunnel and urban site. Concentrations of TSP and OC/EC were highest in the tunnel. Fluorene, Phe, Flt and Pyr were the most dominant PAH compounds in gas phase samples for all three sampling locations, while BaA, Chr, BbF, BkF and BaP were found to be higher in particle phase.
