本研究于2005年对中国市区同时采集的157个土壤样品中的16种多环芳烃进行了分析。A(16)多环芳烃在城市土壤中含量较高，其次是农村土壤和背景土壤。结果表明，中国表层土壤中多环芳烃呈初级分布格局，并与排放清单呈正相关。基于中国近10年(2004年-2013年)的文献研究结果，建立了城乡土壤中多环芳烃的空间分布。多环芳烃浓度具有明显的地理分布，中国东部较高，中国中西部较低。此外，总结了中国河岸土壤中多环芳烃的污染水平，并显示出较高的水平，表明其潜在的来源是受污染的河流。据了解，这是首次根据监测结果在全国范围内全面研究中国表层土壤多环芳烃污染状况。
In this study, 16 polycyclic aromatic hydrocarbons (PAHs) were analyzed in 157 concurrently collected soil samples in 2005 over China. Higher concentration of a(16)PAHs was found in urban soil, followed by rural and background soil. The results indicated that PAHs in Chinese surface soil showed a primary distribution pattern, which was confirmed by the positive correlation with emission inventory. Based on the results of literature over the past 10 years (2004-2013) in China, the spatial distribution of PAHs in urban and rural soil was established. An obvious geographical distribution with PAH concentration was found, as higher in Eastern China and lower in Middle and Western China. Furthermore, PAH pollution in Chinese riverbank soil was summarized and showed higher levels, indicating their potential sources from polluted rivers. According to our knowledge, this is the first time to comprehensively study the PAH pollution status in Chinese surface soil on the national scale based on monitoring results.
