摘要
由于污水处理厂的处理能力有限以及水产家禽养殖业的大量发展,水体中存有一定浓度的雌激素以及孕激素等相关的合成化合物。这些化合物在很低的浓度就具有很强的雌激素活性,能够改变野生生物组织正常的生殖发育。已有不同的方法检测污水处理厂进出水中的这些化合物情况,以此评价污水处理效率和环境风险。但由于这些物质在水中的浓度很低,容易降解,且污水中存在大量悬浮物颗粒、有机物、无机离子等复杂机体的干扰,加大了检测污水中的雌激素和孕激素的难度。本文回顾了已有的检测废水中这些重要环境污染物的分析方法,讨论了从样品处理到分析检测主要的步骤,对比了各种方法灵敏度和适用范围,并对该领域研究进行了展望。
Estrogens and related synthetic compounds have been detected in the aquatic environment,mainly as a result of effluent outfalls of inefficient removal in Waste-Water-Treatment Plants（WWTP） and the excrement of aquaculture and poultry.These compounds show the high physiological activity with very low concentrations and have been associated with certain alarming effects on reproduction and developmental processes.Even with a concentration of 5—6ng/L,17α-ethynylestradiol can exterminate entire fish populations in a whole lake experiment within three years due to the feminization of male fishes.In the last 10 years,an increasing number of studies have been conducted to develop analytical procedures for estimating the levels of the estrogens in the influent and effluent of WWTP and evaluating the risk to human beings and ecosystem.Due to the low concentration and complicated matrix in the wastewater,the determination of natural and synthetic estrogens in wastewater becomes a difficult analytical task.The existing analytical methods for the analyzing these estrogens in wastewater from samplings to procedures,and the methods commonly used in the determination are reviewed.
