摘要
通过分析采集的土壤、沉积物和大气样品,对拉萨郊区的拉鲁湿地多环芳烃污染及其来源进行了初步研究。湿地表层土壤中16种多环芳烃的平均含量的总含量为82.45×10-9,既存在低环数的多环芳烃,又含有高环数的多环芳烃;湿地土壤中的多环芳烃主要来自于大气。
Based on an analysis of samples from soil, sediments and atmosphere, the authors made a preliminary study of polycyclic aromatic hydrocarbons in Lalu wetland within suburban districts of Lhasa City. The averages of 16 sorts of polycyclic aromatic hydrocarbons amount to 82.45×10-9, and the polycyclic aromatic hydrocarbons consist of both low cyclic ones and high cyclic ones. It is held that the polycyclic aromatic hydrocarbons in the wetland soil are derived mainly form the atmosphere.
