| Abstract: | The toxic effects of metal ions and the mixed ions on Brachionus urceus were studied in this paper. The experimental results showed that the 24 h LC_ 50 of Cu 2+, Zn 2+, Cd 2+, Pb 2+ to B. urceus were 83.18 μg/L,4.27 mg/L,7.60 mg/L and 23.44 mg/L respectively. If the mass proportion of these four kinds of metal ions was 120∶20∶6∶1, the 24 h LC_ 50 of the mixed solution to B.urceus was 0.42 mg/L. |
