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 of toxicity made by toxic substances on fish,it is shown that V(Ⅴ)is moderate or highly toxic to Japanese medaka,and adolescent fish is more sensitive to its toxicity.
