Polycyclic musks [Cashmeran (DPMI), Celestolide (ADBI), Phantolide (AHMI), Traseolide (ATII), Tonalide (AHTN) and Galaxolide (HHCB)] were Soxhlet extracted, separated and analyzed in sewage sludge from six different wastewater treatment plants from Guangdong, China, using GC and GC-EI-MS. DPMI, ADBI, HHCB, AHTN were found in all samples, and ATII was not found in any sample. AHMI was detected in five out of six samples. HHCB and AHTN were the two major polycyclic musks found in highest concentrations in sludge. The sludge from municipal wastewater treatment plants contained HHCB, AHTN and DPMI at concentrations between 5.416 and 21.214, 0.715 and 6.195 and 0.599 and 2.870 mg/kg (dry), respectively. The highest concentration was found in sludge from one cosmetic plant at 703.681 mg HHCB/kg (dry). The results indicate that there are two sources of polycyclic musks: domestic sewage and industrial wastewater.
采用气相色谱（GC）和气相色谱-电子轰击质谱联用仪（GC-EI-MS）对来自中国广东6家不同污水处理厂的污泥中的多环麝香（佳乐麝香（DPMI）、吐纳麝香（ADBI）、粉檀麝香（AHMI）、西藏麝香（ATII）、 tonalide（AHTN）和 galaxolide（HHCB））进行索氏提取、分离和分析。所有样品中均检测到DPMI、ADBI、HHCB、AHTN，未在任何样品中检测到ATII。6个样品中有5个检测到AHMI。HHCB和AHTN是污泥中含量最高的两种主要多环麝香。城市污水处理厂污泥中HHCB、AHTN和DPMI的浓度分别为5.416至21.214、0.715至6.195和0.599至2.870mg/kg（干重）。在一家化妆品厂的污泥中发现HHCB的最高浓度为703.681mg/kg（干重）。结果表明，多环麝香有两个来源：生活污水和工业废水。
