本实验应用大型蚤对2种洗涤剂进行急性毒性试验,测定其半数运动抑制浓度(Ec_(50))和半数致死浓度(Lc_(50))。选用62D国际标准实验生物大型蚤按国际标准组织(ISO)规定的方法进行Ec_(50)及Lc_(50)实验。实验结果如下:A洗发精的Ec_(50)和Lc_(50)24小时分别为20mg/L及80mg/L;48小时分别为
In this experiment, two kinds of detergents were tested for their acute toxicity with Daphnia magna. The half inhibitory concentration (Ec_ (50)) and the lethal concentration (Lc_ (50)) were measured. Ecd 50 and Lc 50 experiments were conducted according to International Organization for Standardization (ISO). The experimental results are as follows: A shampoo Ec_ (50) and Lc_ (50) 24 hours were 20mg / L and 80mg / L; 48 hours were
