| 摘 要： | 以不同月龄的日本青鳉为受试生物,采用半静止生物测试法,比较研究V(Ⅴ)对日本青鳉成鱼和幼鱼的急性毒性效应.结果表明:V(Ⅴ)对日本青鳉成鱼的72 h和96 h LC50分别为4.91 mg/L和2.73 mg/L,安全质量浓度为0.273 mg/L,钒对幼鱼的72 h和96 h LC50分别为0.85 mg/L和0.43 mg/L,安全质量浓度为0.042 7 mg/L.根据有毒物质对鱼类的急性标准可得钒对日本青鳉有中至高等毒性,幼鱼对钒的毒性更为敏感.

| Abstract: | Different month aged Japanese medakas(Oryzias latipes) were selected as test species to compare acute toxicity effect made by Vanadium(Ⅴ)on adult fish and adolescent fish by using the semi-static bioassay method.The result showed that 72 h LC50 and 96 h LC50 made by V(Ⅴ)on adult fish were 4.91 mg/L and 2.73 mg/L,and the safety concentration was 0.273 mg/L.72 h LC50 and 96 h LC50 made by V(Ⅴ)on adolescent fish were 0.85 mg/L and 0.43 mg/L,and the safety concentration was 0.042 7 mg/L.Based on the criterion o... |
