摘要
采用室内试验测试植物灭螺剂"螺威"对斑马鱼、日本鹌鹑和青虾的毒性,评价其对环境的影响。试验前按正式试验条件先预试,求出植物灭螺剂"螺威"对斑马鱼、日本鹌鹑和青虾的毒性影响范围。正式试验时在此范围内按一定的比例级差设置若干处理浓度,每个浓度设3个重复,并设一组空白对照。4%螺威粉剂(TDS)植物灭螺剂使用浓度高于LC50值,对鸟类和虾类为中毒,对鸟的实际危害影响不大,对鱼类风险较大。
The purpose of the paper is to test the toxicity of the plant molluscicide ＂Lo-wei＂ to zebra fishes,Japanese quails and freshwater shrimps in laboratory to evaluate its impact on the environment.According to the rightful test conditions,the toxicity range of the molluscicide on the zebra fish,Japanese quail and freshwater shrimp was previous tested.In the rightful test we set different molluscicide concentrations by a certain percentage in this range,with 3-time repeat tests for each concentration,and a set of contrast test.When ＂Lo-wei＂ powder（TDS） concentration in 4 percent is higher than the safe level of plant molluscicide LC50 value,it generates a moderate toxicity to birds and shrimps,little effect to birds actually and a greater risk to fishes.
