为了评价与不同处理技术的污水处理厂（WWTPs）相连的河流的地表水和沉积物质量，在德国南部的4个污水处理厂的上游和下游采集了原生水和沉积物样品，进行了斑马鱼鱼胚胎试验（FET）。其中两个污水处理厂连接到康斯坦茨湖的支流Schussen河，并使用砂滤器，通过絮凝进行最终水净化。另外两个位于施瓦本阿尔布地区的Schmiecha和Eyach河上，20年前配备了粉末活性炭阶段，最初旨在减少纺织工业的污渍释放。在胚胎发育的规定时间点研究了胚胎毒性的几个终点，包括死亡率、畸形、孵化率降低和心率。发现在配备砂滤的污水处理厂下游收集的水和沉积物中的胚胎毒性比在两个配备粉末活性炭阶段的污水处理厂下游获得的样本更高。
In order to evaluate surface water and the sediment quality of rivers connected to wastewater treatment plants (WWTPs) with different treatment technologies, fish embryo tests (FET) withDanio reriowere conducted using native water and sediment samples collected upstream and downstream of four WWTPs in Southern Germany. Two of these WWTPs are connected to the Schussen River, a tributary of Lake Constance, and use a sand filter with final water purification by flocculation. The two others are located on the rivers Schmiecha and Eyach in the area of the Swabian Alb and were equipped with a powdered activated carbon stage 20 years ago, which was originally aimed at reducing the release of stains from the textile industry. Several endpoints of embryo toxicity including mortality, malformations, reduced hatching rate, and heart rate were investigated at defined time points of embryonic development. Higher embryotoxic potentials were found in water and sediments collected downstream of the WWTPs equipped with sand filtration than in the sample obtained downstream of both WWTPs upgraded with a powdered activated carbon stage.
