摘 要:
采用静水生物毒性试验法测定了Cu^2＋、食盐对金鱼幼鱼的急性毒性作用及安全浓度评价，浓度梯度按等对数间距设置，半致死浓度采用直线内插法进行计算。获得了Cu^2＋和食盐对金鱼幼鱼24h,48h、96h的LC50值分别为0．50，0．450，0．266mg／L和13．404，10．308，7．042。提出了Cu^2＋和食盐对金鱼幼鱼安全浓度分别为0．00266mg／L和0．704mg／L。为金鱼幼鱼防病治病、水质管理及环境保护提供了依据。[著者文摘]

Abstract:
Acute toxic effects of Cu^2＋ and table salt on juvenile goldfish and safe concentration of table salt were investigated. The LC50 of Cu^2＋ on 24 h, 48 h, 72 h and 96 h were 0.50, 0. 450, 0. 375 and 0.266 rag/L, and that of table salt were 13. 404, 10. 308, 8. 553, and 7. 042 mg/L. The safe concentration of Cu^2＋ and table salt were 0. 002 66 and 0. 704 mg/L. The results provide useful information for goldfish disease prevention, water quality control and environmental protection.[著者文摘]
