摘要
硅氧烷具有潜在的环境持久性、生物累积性和毒性等典型特征,已成为近年来国际上普遍关注的新污染物。因具有低表面张力、高热稳定性和出色的润滑性等特性,硅氧烷被广泛应用于日常生产生活,且其产量和消费量均呈逐年增长趋势。随着人类活动中该类化合物的大量消耗,目前已在各种环境介质、个人护理品、生物基质、硅胶产品以及食物等中频繁检出硅氧烷。同时硅氧烷在不同介质中还能转化成多种中间产物,因此逐渐引起了人们的重视。目前,针对硅氧烷化合物的分析方法复杂多样,该文对不同环境介质中样品的采集、前处理方法、硅氧烷的仪器分析方法、硅氧烷及其降解产物的非靶标筛查等内容进行了综述,并对采样及后续实验中需要解决的问题进行了阐述,以期对硅氧烷后续研究及前期样品分析方法等的选择提供参考。
Siloxanes have typical characteristics such as potential environmental persistence,bioac⁃cumulation,and toxicity,and have become a type of emerging pollutants of widespread international concern in recent years.Due to their low surface tension,high thermal stability and lubricating prop⁃erties,siloxanes have been widely used in daily production and life,and their production and con⁃sumption are both increasing year by year.With the large consumption of these compounds in human activities,they have been frequently detected in various environmental media,personal care prod⁃ucts,biological matrices,silica gel products,and even food.Meanwhile,the various intermediate products formed by the degradation reactions of siloxanes in different media have gradually attracted attention.At present,the analysis methods of siloxane compounds reported in literatures were com⁃plex and diverse.And then,this article provided a review of sample collection,pretreatment meth⁃ods,instrumental analysis of siloxanes,and non-targeted screening of siloxanes and their degrada⁃tion products in different environmental matrices,as well as an elaboration of the problems that need to be solved in the sampling and subsequent experiments.It is hoped that this review can provide a reference for the development direction of the follow-up study of siloxanes and the selection of analyti⁃cal methods.
