| 摘 要： | 目的]证明生活污水中的氨、氯化物、磷对萼花臂尾轮虫具有急性毒害作用,探索利用轮虫来监测水质的方法。方法]利用24 h标准化急性毒性试验法测定3种毒物在6个试验浓度下对轮虫的毒害作用,设1个对照浓度,每浓度4组重复,各放10个轮虫。结果]NH4＋、Cl-和普通洗衣粉在24 h之内,轮虫全部死亡的最低浓度依次为49.00、4.90和24.00 mg/L,此时的半数死亡（LD50）时间分别为8、6和8 h;全部存活的最高浓度依次为11.50、2.40和1.35 mg/L。当毒物的浓度降低到一定限度时,对轮虫就无急性毒害作用。随着毒物浓度的上升,LD50时间出现的越来越早,轮虫的死亡速度也越来越快。结论]生活污水中的氨、氯化物、磷对轮虫的影响是随着浓度的增加其死亡率不断上升,半数死亡的时间不断提前,急性致死力不断增强。

| Abstract: | Objective] The method supervising the water quality with rotifer(Brachionus calyciflorus) was explored through the verification of the acute toxicity of the NH4+,Cl-and ordinary washing powder to it.Method] The toxicity efficiency of 3 kinds of materials with 6 concentrations on rotifer was measured with method of 24 hour-standardization test of acute toxicity.There were 10 rotifers in each treatment and every treatment,including the CK,was with 4 repetitions.Results] Under the treatment of NH4+,Cl-and o... |
