Acute toxicity and feeding rate inhibition of effluent from a wastewater treatment plant and its adjacent stream water on Daphnia magna and Moina macrocopa were comparatively studied. The acute toxicity of the final effluent (FE) fluctuated greatly over the sampling period from January to August 2009. Toxicity identification results of the FE in July 2009 showed that Cu originating from the Fenton's reagent was likely a key toxicant. In addition, the feeding rate of both species was still inhibited by the FEs in which acute toxicity was not observed. These findings indicate that the feeding response would be a useful tool for monitoring sublethal effects of industrial effluents. For the acute toxicity test, M. macrocopa was more sensitive than D. magna, but the opposite result was true in the case of the feeding rate inhibition. These suggest that different species have different sensitivities to toxic chemicals and to the test methods.
比较研究了污水处理厂及其相邻溪流水中废水的急性毒性和对大型溞和大型水蚤的摄食率抑制作用。2009 年 1 月至 8 月的采样期间，最终出水（FE）的急性毒性波动很大。2009 年 7 月 FE 的毒性鉴定结果表明，芬顿试剂中的 Cu 可能是一种关键的有毒物质。此外，尽管 FE 没有表现出急性毒性，但仍抑制了两种生物的摄食率。这些发现表明，摄食反应将是监测工业废水亚致死效应的有用工具。对于急性毒性试验，大型溞比大型水蚤更敏感，但在摄食率抑制的情况下则相反。这表明不同的物种对有毒化学物质和测试方法有不同的敏感性。
