中文摘要：

挥发性甲基硅氧烷（Volatile methylsiloxane，VMS）广泛用于许多工业生产过程，并频繁添加于各类消费品，特别是个人护理品（PCPs）中.VMSs产量高、用途广，源源不断进入到环境中，其进入环境后的环境行为及归趋已受到广泛关注.VMSs理化性质较为特殊，兼有疏水性与挥发性，且难以进行生物降解，因此VMSs进入环境后潜在的生态风险，特别是远距离迁移、持久性、生物富集性与生物放大性已成为关注热点.本文概述了几种典型的VMSs的来源及理化性质，综述了其在全球范围内多种环境介质中的分布与行为归趋，包括大气、水体、土壤与底泥、生物质、污水处理厂进出水及污泥等，并总结了VMSs生物富集性与生物放大性的相关研究.针对VMSs存在的环境风险和健康风险，提出了今后的研究方向.

英文摘要：

Volatile methylsiloxanes （VMSs） are widely used in various industrial processes and frequently added to consumer products, especially to personal care products （PCPs）. With high production and wide application, VMSs are released to the environment continuously. Concerns have been raised recently regarding their behaviors in the environment after their release. Furthermore, VMSs possess a rather unusual combination of physicochemical properties, including hydrophobicity and volatility. They are not readily biodegradable. Recent concerns include the potential environmental risks of VMSs, as well as their long range transport, persistence, bioaccumulation and biomagnification. Firstly, the sources and physicochemical properties of several typical VMSs were introduced in this paper. The occurrences, behaviors and fates of several VMSs in the environment were reviewed. The data cover air, water, soil and sediment, biota, influent and effluent of wastewater treatment plant （WWTP） and biosolid samples. Moreover, the studies of bioaccumulation and biomagnification effects of VMSs were also discussed. Finally, suggestions for further research are proposed, regarding the potential risks of VMSs to the environment and human health.
