| 摘 要： | 运用评价化学品毒性藻类测试的标准实验方法 ,得到铜、锌和锰对蛋白核小球藻生长的安全浓度分别为31.8μg/L、65.0μg/L和 5.5mg/L ,抑制蛋白核小球藻生长的 96h EC50 分别为 67.3μg/L、473.0 μg/L和 17.0mg/L .实验结果表明无论从安全浓度还是从 96h EC50 考虑 ,都证明抑制蛋白核小球藻生长的毒性由大到小的顺序是铜 >锌 >锰 .不同金属离子与藻细胞的不同亲和性是导致金属离子抑制蛋白核小球藻生长毒性差异的主要原因 .

| Abstract: | A standard method of algal bioassay for evaluating the toxicity of toxic chemicals was applied in the study. It was found that safety concentrations of Cu, Zn and Mn for Chlorella pyrenoidosa's growth were 31.8 micrograms/L, 65.0 micrograms/L and 5.5 mg/L, and 96 h-EC50 were 67.3 micrograms/L, 473.0 micrograms/L and 17.0 mg/L, respectively. According to both safety concentration and 96 h-EC50, the toxic sequences of these metals from high to low on the inhibition of C. pyrenoidosa's growth were Cu, Zn and Mn. The different affinities between different metal ions and algal cells are mainly responsible for the different inhibitions of C. pyrenoidosa's growth. |
