摘要
本试验对抗坏血酸稀土对鱼类的急性毒性进行了研究。结果表明:抗坏血酸稀土对鲢鱼、草鱼、金鱼和泥鳅的96hrTLm值为50.14～495.27mg/l。根据鱼类急性毒性毒物的分级暂定标准,抗坏血酸稀土对鱼类属低毒物质。
The present work was carried out to investigate the acute toxicity of rareearth ascorbate in fishes. The results showed that the 96 hr TLm values ofrare earth ascorbate for 4 fishes (silver carp, grass carp, goldfish and loach )ranged from 50.14 to 495.27 mg/l. It was amony the substances of low toxicityaccording to the system of classification of chemicals for acute toxicity infishes regulated by China.
