摘要: 随着日化产品的大量使用,合成麝香(SMCs)广泛分布于环境中。由于这类化合物亲脂憎水性较强、环境中难降解、易生物富集,并具有潜在致癌和环境激素作用,对人类的健康将产生巨大的威胁,目前越来越受到关注。本文综述了合成麝香类化合物的来源及其在环境中的残留现状,总结了不同环境介质中合成麝香的污染特征,特别是水体环境中的赋存状况及迁移转化等方面的研究进展,并对现有环境样品中该类化合物的分析方法进行了比较。总体上,环境样品(如大气、水、土壤、沉积物、生物组织等)中合成麝香类化合物的前处理方法正朝着环境友好、快速的方向发展;检测技术多采用气相色谱质谱法,而超高效液相色谱串联质谱、全二维高分辨质谱等高灵敏度的技术将会被逐渐应用到实际样品分析中,同时随着大环类和脂环类合成麝香的生产和使用,这两类化合物的污染调查以及分析技术方面的发展也成为未来合成麝香类化合物分析技术及残留现状研究的热点。

Abstract: With abundant production and use of daily chemical products, synthetic musk compounds (SMCs) have entered and distributed widely in the environment. SMCs are strongly lipophilic and hydrophobic, difficult to degrade in the environment, and easy to bioaccumulate. They have potential carcinogenic effects and environmental hormone toxicity, and greatly threaten the health of human beings. More and more attention has been paid to SMCs. In this paper, the pollution source and pollution status of SMCs were reviewed. The pollution levels of SMCs in different environmental media were summarized, and a deep discussion was focused on the concentration and migration of SMCs in aquatic environments. Then, the analysis methods of SMCs in different matrixes were compared. Nowadays, the development of pretreatment technology of SMCs in environmental samples such as air, water, soils, sediments and biological tissues is rapid and more friendly to the environment. For the detection technology, the gas chromatographymass spectrometry (GC-MS) has been used widely, and the high sensitive technology such as ultraperformance liquid chromatographytandem mass spectrometry (UPLC-MS-MS) or gas chromatography×gas chromatography (GC×GC)high resolution mass spectrometry will be applied in real analysis. Studies on pollution status and analysis method of macrocyclic and alicyclic synthetic musks in the environment will be hotspots.
