复杂环境介质中典型EDCs前处理技术和分析方法研究进展

Pretreatment technology and analytical method of the representative EDCs in complex environment media

环境内分泌干扰物(EDCs),尤其是痕量酚类和类固醇类EDCs,在复杂环境介质(如水、沉积物、污水厂进出水、污泥、生物样品等)中的前处理技术和分析方法成为当前亟需解决的问题。建立完善的复杂环境介质中准确、灵敏的分析检测技术成为摆在环境科学工作者面前的重要任务之一。鉴于我国EDCs研究的紧迫性和滞后性,将酚类和类固醇类EDCs作为一个有机整体详细论述了在复杂环境介质中的前处理技术和分析方法,包括样品采集、保存、萃取、净化、衍生化、仪器分析、生物学分析等,为典型EDCs的风险评价、污染特征和污染控制措施研究提供了基础资料,具有明显的理论意义、社会环境意义和应用价值。

Due to the complexity of the environmental matrix,such as water,sediment,influent,effluent,sludge,biological sample and so on,it is very difficult to treat and analyze the EDCs in natural environment.Therefore,it is of crucial importance to develop the pretreatment technology and analytical method for the accurate and sensitive determination of the EDCs in the complex media. In consideration of the urgency and hysteresis of study on EDCs,phenolic and steroidal EDCs are selected as target compounds for disscussing the pretreatment technology and analytical method for complex matrix. Research progress has been extended to sample collection,preservation,extraction,purification,derivation,instrument detection,biological analysis,and so on. This paper provides more comprehensive fundamental data for risk assessment,pollution characteristic and contamination control of the representative EDCs in complex environment media. The research has remarkable significances in theory,social,environmental health and engineering application.
