摘要
环境内分泌干扰物(EDCs)是指干扰生物体内保持自身平衡和调节发育过程中天然激素的合成、分泌、运输、代谢、结合、反应、消除等生物过程的外源性化学物质,这类物质的存在会干扰人类和野生动物的内分泌系统,带来生殖障碍、发育异常、免疫功能减弱等问题。EDCs,尤其是使用最为广泛的酚类EDCs,在水环境中的污染特征研究已是当前科学界和公众共同关注的热点问题之一。环境样品基质非常复杂,使得痕量酚类EDCs的分析检测难度较大。该文对近年来环境水体中酚类EDCs的分析方法进行了综述,分别对样品前处理与检测分析技术进行了介绍,其中前处理技术包括样品萃取、样品净化和样品衍生化,检测分析技术包括化学分析和仪器分析。最后对酚类分析方法进行了展望。
Endocrine disrupting chemicals（ EDCs）,as a kind of exogenous substances,can block or mimic the synthesis,secretion,transport,metabolism,binding and elimination of natural hormones which are responsible for the maintenance of homeostasis, reproduction, development and action.EDCs interfere with the function of endocrine system in human and wildlife,and consequently cause adverse effects on development, reproduction, non-reproduction and immune system. Therefore,the pollution characteristics of EDCs in aquatic environment,particularly phenolic EDCs,are widely used,which have attracted a great deal of scientific and public attention worldwide. However,it is very difficult to determine phenolic EDCs in actual environment due to their low-dose and matrix complexity. In this review,analysis methods of the phenolic EDCs in water,including sample pretreatment and analysis technique,in recent years are summarized. The prospect about the analysis methods of phenolic endocrine disruptors is also discussed.
