| 摘 要： | 通过单因子静态急性毒性试验法和等毒性溶液法分别研究了重金属离子铜、锌对汤匙华哲水蚤的急性毒性和联合毒性效应.急性毒性试验结果表明:铜、锌离子对汤匙华哲水蚤24 h半致死浓度(LC50)分别为0.481、3.221 mg/L;48h LC50分别为0.383、1.573 mg/L;72h LC50分别为0.315、0.471 mg/L.铜、锌联合毒性致毒特征表明:高强度的锌离子对铜离子有拮抗作用,高强度的铜离子对锌离子有协同作用.

| Abstract: | Acute toxicity and joint toxicity of copper,zinc on Sinocalanus dorrii are studied by single factor static acute toxicity test method and equal toxic solution method. Acute toxicity test results showed that the median lethal concentrations( LC50) of copper ions,zinc ions for 24 h to Sinocalanus dorrii were 0. 481,3. 221 mg/L; LC50for 48 h were 0. 383,1. 573 mg /L; LC50for 72h were 0. 315,0. 471 mg /L. The joint toxicity presented characteristics shows that high-strength of copper ions performs synergistic effect and high-strength of zinc ions performs antagonistic effect to Sinocalanus dorrii. |
