摘要Concentrations and compositions of PAHs and oxygenated PAHs (OPAHs) in four size ranges of ambient particles (<1.1, 1.1-3.3, 33-9.0 and >9.0 mu m) collected in Xi'an and Guangzhou, two megacities of China, during the winter and summer of 2013 were measured and compared with those in 2003. The TSP-equivalent concentrations of Sigma 14PAHs in Xi'an and Guangzhou are 57 +/- 20 and 18 +/- 23 ng m(-3) in winter, 5-10 times higher than those in summer. PAHs in both cities are dominated by 5- and 6-ring congeners in summer. In contrast, they are dominated by 4- and 5-ring congeners in winter, probably due to enhanced gas-to-particle phase partitioning of the semi-volatile PAHs. TSP-equivalent Sigma OPAHs during winter are 54 +/- 15 and 23 +/- 32 ng m(-3) in Xi'an and Guangzhou and dominated by 5-ring OPAHs.
