摘  要:
[目的]研究不同浓度Pb2+对波纹巴非蛤的急性毒性。[方法]采用水生动物急性毒性试验方法,研究了不同浓度(3.0~7.0mg/L)Pb2+对波纹巴非蛤(Paphia undulata)的急性毒性,分别对96 h半致死浓度(4.119 mg/L)和安全浓度(0.041 mg/L)下0~120 h各组织中Pb2+的蓄积量进行了测定。[结果]Pb2+对波纹巴非蛤24、48、72和96 h的半致死浓度(LC50)分别为7.187、5.788、4.646和4.119 mg/L,安全浓度(SC)为0.041 mg/L。铅对波纹巴非蛤的毒性级别为高毒级(LC50为1~100 mg/L)。在96 h半致死浓度和安全浓度下,120 h波纹巴非蛤各组织Pb2+的蓄积量从大到小均依次为鳃、内脏、肌肉。[结论]食用波纹巴非蛤有一定的安全风险。

摘  要:
[Objective] The aim was to study the acute toxicity of different concentrations Pb2 +on Paphia undulate.[Method]By using aquatic animal acute toxicity method,the acute toxicity of different concentrations Pb2 +( 3. 0- 7. 0 mg/L) on P. undulata were studied; the accumulations of Pb2 +within 0- 120 h under 96 h half lethal concentration( 4. 119 mg / L) and the safe concentration 0. 041 mg / L were tested respectively.[Result] The results showed that the half- lethal concentrations( LC50) of Pb2 +at 24,48,72 and 96 h were 7. 187,5. 788,4. 646,4. 119 mg / L,and the safe concentration( SC) was 0. 041 mg / L. The toxic level of Pb2 +on P. undulata was high( LC501- 100 mg / L). Under 96- h half lethal concentration and the safe concentration,the 120 h contents of Pb2 +were gill > viscera > muscle. [Conclusion] Eating P. undulata has a certain risk.
