中文摘要：

在苏州溪的七合成麝香的污染层次和分布在这研究被调查。二多不的麝香， 1 ， 3 ， 4 ， 6 ， 7 ， 8-hexahydro-4 ， 6 ， 6 ， 7 ， 8 ， 8-hexamethylcyclopenta (g) -2-benzopyran ( HHCB )和 7-acetyl-1 ， 1 ， 1 ， 3 ， 4 ， 4 ， 6-hexamethyl-1 ， 2 ， 3 ， 4-tetrahydronaphthalene ( AHTN )，在所有样品被发现。HHCB 和 AHTN 的范围从 8 ng/L 到 138 ng/L 并且从 1 ng/L，并且从 2 ng/g 到表面水里的 25 ng/L 到 77 ng/g (干燥重量) 并且从 1 ng/g 到 31 ng/g (干燥重量) 在沉积分别地。HHCB 和 AHTN 的全部的集中在表面水里显示出明显的空间变化：上面的活动范围(郊区) 13 不到更低的功课(城市的区域) ；并且在沉积，麝香层次在城市的区域也是更高的。也 seasonaly 显示出的分发模式在表面水和沉积里两个都改变了特征。分发系数(Kp ) 和标准化分发系数(Koc ) 通过麝香集中和 octanol 水分区系数(Kow ) 被计算。结果证明 AHTN 更容易被专心于沉积。麝香的吸附与在苏州溪增加全部的器官的碳(TOC ) 被增加。HHCB 和 AHTN 的重要积极关联在这研究被发现，它显示了一样的污染来源：香料物质的使用和分泌物。

英文摘要：

Contamination levels and distribution of seven synthetic musks in Suzhou Creek were investigated in this study. Two polycyclic musks, 1, 3, 4, 6, 7, 8-hexahydro-4, 6, 6, 7, 8, 8-hexamethylcyclopenta（g）-2-benzopyran （HHCB） and 7-acetyl-1, 1, 1, 3, 4, 4, 6-hexamethyl-1, 2, 3, 4-tetrahydronaphthalene （AHTN）, were found in all samples. The ranges of HHCB and AHTN were from 8 ng/L to 138 ng/L and from 1 ng/L to 25 ng/L in surface waters, and from 2 ng/g to 77 ng/g （dry weight） and from 1 ng/g to 31 ng/g （dry weight） in sediments respectively. The total concentration of HHCB and AHTN showed obvious spatial change in surface waters： the upper reaches （suburb） 13 less than the lower course （urban area）; and in sediments, the musk levels were also higher in urban area. The distribution pattern also showed seasonaly varied characteristics both in surface waters and sediments. The distribution coefficient （Kp） and standardized distribution coefficient （Koc） were calculated through musk concentrations and octanol-water partition coefficient （Kow）. The results showed that AHTN was more easily absorbed in sediments. The adsorption of musk was increased with the increasing of total organic carbon （TOC） in Suzhou Creek. The significant positive correlation of HHCB and AHTN was found in this study, which indicated the same pollution source： the use and discharge of flavoring substances.
