Zooplankton is very sensitive to various agrochemicals including glyphosate herbicides which may arise from runoff in paddy fields. In this study, acute toxicity test of Glyphosate-Based Herbicides (GBHs) was conducted to and . Acute toxicity test was performed to both organisms at the Glyphosate concentrations of 20, 80, 160, 320, and 640 mg/L in exposure time of 12 h, 24 h, and 48 h. The mortality and morphology were observed to determine the LC and the effect of its morphology. The test showed that was more susceptible than . The LC of GBHs to and for its different exposure time were respectively show as follows: 76.67 mg/L and 207.89 mg/L (12 h); 36.2 mg/L and 159.8 mg/L (24 h); and 21.34 mg/L and 92.93 mg/L (48 h). There were no significant differences of the alteration of spin length, body length, and head length of to exposure of GBHs, except the head width. While body length alteration of was significantly different towards the increase in concentration.
浮游动物对包括草甘膦除草剂在内的各种农用化学品非常敏感，这些化学品可能来自稻田径流。在本研究中，对[具体物种1]和[具体物种2]进行了草甘膦基除草剂（GBHs）的急性毒性试验。在12小时、24小时和48小时的暴露时间内，以20、80、160、320和640毫克/升的草甘膦浓度对两种生物进行急性毒性试验。观察死亡率和形态以确定LC50及其对形态的影响。试验表明，[具体物种1]比[具体物种2]更敏感。GBHs对[具体物种1]和[具体物种2]在不同暴露时间的LC50分别如下：76.67毫克/升和207.89毫克/升（12小时）；36.2毫克/升和159.8毫克/升（24小时）；21.34毫克/升和92.93毫克/升（48小时）。除头部宽度外，[具体物种1]的刺长、体长和头长的变化对GBHs暴露无显著差异。而[具体物种2]的体长变化随浓度增加有显著差异。
