2008年11月至2009年9月，在黄海北部小买岛、老湖滩和漳子岛3个采样站采集了气相和颗粒相多环芳烃（PAHs）样品，研究了其大气输送势和气相/颗粒分布。多环芳烃的组成以气态化合物为主。颗粒相多环芳烃占总浓度的百分比在采暖期高于非采暖期。从小麦岛到漳子岛，萘和苊与菲、蒽和二苯并（a,h）蒽的比值呈增加趋势，可称为局部大气蒸馏的多环芳烃。研究了多环芳烃的气体/颗粒分配系数Kp及其与过冷液蒸汽压的关系。3个站点的所有样本的logkp与logpºl的回归均显示出显著的相关性，其值在0.56 ~ 0.66之间（p< 0.01）。jung - pankow吸附模型和辛醇-空气分配系数吸附模型都倾向于低估对大多数多环芳烃的吸附，但吸附模型似乎比jung - pankow模型更适合于预测多环芳烃的颗粒分数。
Samples of gas- and particle-phase polycyclic aromatic hydrocarbons (PAHs) were collected at three sampling stations (Xiaomai Island, Laohutan, and Zhangzi Island) in the north Yellow Sea, China during November 2008 and September 2009 to study their atmospheric transport potential and the gas/particle distributions. The composition of PAHs was dominated by gaseous compounds. The percentages of the particle-phase PAHs to the total concentrations were found to be higher during the heating period than the non-heating period. The ratios of naphthalene and acenaphthene to phenanthrene, chrysene and dibenzo(a,h)anthracene showed an increasing trend from Xiaomai Island to Zhangzi Island, which can be called as the local atmospheric distillation of PAHs. Gas/particle partitioning coefficients (Kp) and their relationship with the sub-cooled liquid vapor pressures (pºL) of PAHs were investigated. The regressions of logKpversus logpºLgave significant correlations for all samples of the three sites withr2values in the range 0.56–0.66 (p< 0.01). Both Junge–Pankow adsorption model and octanol–air partition coefficient absorption model tended to underestimate the sorption for most PAHs, but the absorption model appeared to be more suitable for predicting the particle fraction of PAHs than the Junge–Pankow model.
