| 摘 要： | 选择北京城近郊房山与密云地区的土壤进行了多环芳烃的定量分析，同时探讨了多环芳烃在土壤中的分布特征与来源。研究结果显示：密云、房山两地土壤中多环芳烃的含量值具有明显差异，提示了两地工业活动影响强度的不同；各采样区土壤中多环芳烃总量的平均值在45．98～388．23ng／g变化，根据多环芳烃的特征参数可以推测研究区土壤中的多环芳烃主要来自于化石燃料的不完全燃烧。 |

| Abstract: | The concentrations of polycyclic aromatic hydrocarbon (PAHs) compounds in soil samples collected from Miyun and Fangshan districts of Beijing were quantitatively analyzed. The distributing characteristics and sources of these compounds were discussed. The results show that there are obvious differences in PAHs content in soils between Miyun and Fangshan area. The total PAHs concentrations are in a range from 45.98 ng/g to 388.23 ng/g.It also indicates that the PAHs in the soils are closely related to the industrial activities. Depending on the distribution characteristics of PAHs, the incomplete pyrolysis of the fossil fuel may be the dominant source of PAHs pollution in the study area. |
| Keywords: | polycyclic aromatic hydrocarbons (PAHs) distribution soil Beijing suburb |
