Polycyclic musks were measured in surface sediments collected from the Pearl River Delta and Macao coastal region, South China, to investigate contamination from domestic sewage. Three polycyclic musk compounds-4-acetyl-1,1-dimethyl-6-tert-butylindan, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta(g)-2-benzopyran (HHCB), and 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN)-were detected in sediment samples. Two polycyclic musks, HHCB and AHTN, were dominant components in sediment, consistent with the use pattern of polycyclic musks by perfume industries in the Pearl River Delta region. The concentrations of total polycyclic musks ranged from 5.76 to 167 microg/kg. Because of the large amount of domestic sewage and industrial wastewater discharged from the city of Guangzhou, the highest concentration of polycyclic musks was found in sediments from the Zhujiang River. The significant positive correlation between the HHCB to AHTN ratios and the concentrations of polycyclic musks suggested that the HHCB to AHTN ratio could be used as a tracer for source discrimination and for the degree of degradation in the environment.
对采自中国南方珠江三角洲和澳门沿海地区的表层沉积物中的多环麝香进行了测定，以调查生活污水造成的污染。在沉积物样本中检测到三种多环麝香化合物——4-乙酰基-1,1-二甲基-6-叔丁基茚满、1,3,4,6,7,8-六氢-4,6,6,7,8,8-六甲基环戊并[g]-2-苯并吡喃（HHCB）和7-乙酰基-1,1,3,4,4,6-六甲基-1,2,3,4-四氢萘（AHTN）。两种多环麝香，HHCB和AHTN，是沉积物中的主要成分，这与珠江三角洲地区香水行业多环麝香的使用模式一致。多环麝香的总浓度范围为5.76至167微克/千克。由于广州市排放大量生活污水和工业废水，珠江沉积物中多环麝香的浓度最高。HHCB与AHTN的比值与多环麝香浓度之间存在显著正相关，这表明HHCB与AHTN的比值可作为环境中来源判别和降解程度的示踪剂。
