摘　　要：[目的]研究锂电池泄露对大型蚤的急性和慢性毒性。[方法]选择大型蚤作为受试生物,进行纳米氢氧化镍对典型水生生物大型蚤的急性和慢性毒性试验。[结果]大型蚤对纳米氢氧化镍的耐受浓度随着时间变化差异很大,在24 h内大型蚤耐受浓度为0～3.83mg/L,在48 h内耐受浓度迅速降低至0～0.69 mg/L,而48～96 h后耐受浓度变化不大;纳米氢氧化镍在短时间(0～2 d)引起大型蚤死亡并引起大型蚤繁殖延迟。[结论]该研究为锂电池泄露后纳米氢氧化镍对环境的影响分析提供参考依据。[ Objective ] The research aimed to study the acute toxicity and chronic toxicity of lithium battery leakage on Daphnia magna. [ Method ] Choosing Daphnia magna as test biology, the acute and chronic toxicity of nanometer nickel hydroxide to model aquatic was studied. [ Result] The tolerance of the Daphnia magna to nanometer nickel hydroxide varied wildly with time. The concentration in 24 h was 0 - 3.83 mg/L while reduced to 0 -0.69 mg/L in 48 h,and changed little after 48 -96 h. Nanometer nickel hydroxide caused Daphnia magna to and reproductive - delayed die in two days. [ Conclusion]The study provides the reference for environmental impact analysis of nanometer nickel hydroxide from lithium battery leakage.
