| 摘 要： | 采集玉渊潭不同深度的沉积物样品，测定了其中多环芳烃和正构烷烃的含量。结果表明5－15cm层多环芳烃含量最高，0－5cm层次之，15－25cm层最低，参照若干多环芳烃指数的计算，进行源的识别，正构烷烃含量的分布与多环芳烃类相似，多环芳烃的吸附量与沉积物中的有机碳含量呈很高的相关性，相关系数为0.99，而正构烷烃的吸附量则随沉积物粒径的减小而增高。

| Abstract: | Concentration and Distribution of PAHs and n Alkanes in the sediment of Yuyuantan Lake were investigated. The results showed the changes of environmental quality of Beijing in the process of industrialization. Samples were collected from different depth intervals. The concentration of PAHs in the top layer was not the highest among three collected samples from Yuyuantan Lake. The sources of PAHs were investigated according to PAHs indexes. The mechanism of adsorption was also studied. |

| Keywords: | PAHs normal alkane sediment adsorption Beijind |
