At both sites, 24 h samplings for two consecutive days were performed between August 2002 and January 2003. Particle-bound PAHs (p-PAHs) were collected on quartz filters and gas-phase PAHs (g-PAHs) were measured on glass cartridges using PUF Sampler, respectively. The average g-PAHs (N = 19) concentrations at TIP and THUC sampling sites were found to be 1305.4 ng m-3 and 646.2 ng m-3; average p-PAHs (N = 19) concentrations at both sampling sites were recorded as 129.1 ng m-3 and 85.9 ng m-3, respectively. Correlation studies between PAHs concentrations and meteorological parameters revealed that temperature had greater effects on g-PAHs and p-PAHs, moreover, PAHs sources were resolved by using principal component analysis (PCA) and hierarchical cluster analysis (HCA). The major sources of PAHs were diesel vehicles and industrial source at TIP site. Moreover, incineration, gasoline vehicle and stationary emission sources such as power plant, industrial source and so on are the major contribution sources for PAHs at THUC sampling site.
