| 摘 要： | 采用发光细菌法（费氏弧菌，Vibrio．fisheri）对镉污染的土壤及Cd^2＋进行毒性检测，分析了不同浓度Cd^2＋和不同镉污染梯度的土壤对发光细菌发光抑制率的影响。结果表明，在0．32～48mg·L^-1这个浓度区间，Cd^2＋对费氏弧菌的剂量一效应关系为CUBIC曲线，相关系数在0．92～0．96之间。镉污染土壤的临界浓度为10mg·kg^-1；土壤镉污染程度越重其pH值越高。

| Abstract: | The toxic examination of Cd^2＋ and Cd polluted soil are developed with Vibrio. fisheri luminescence, the impacts of different concentration of Cd^2＋ and different Cd polluted soil on restraining rate of luminescent bacteria are analyzed. The critical concentration of Cd polluted soil is 10 mg·kg^-1, and more Cd pollution degree the soil has, higher pH value it is. |
