摘要
采用常温静水实验法，分别探讨了聚维酮碘、碘三氧对异育银鲫（Carassius aurutus gibelio）鱼苗（体长1．0～1．5cm）的急性毒性效应。结果表明，聚维酮碘对异育银鲫鱼苗24h、48h、96h的半致死浓度分别为43．45mg／L、24．21mg／L、21．38mg／L，安全浓度为2．14mg／L；碘三氧对异育银鲫鱼苗24h、48h、96h的半致死浓度分别为52．36mg／L、33．11mg／L、26．73mg／L，安全浓度为2．67mg／L。
The acute toxicity of pvidone-iodine(PVPⅠ)and IO_3 on allogynogenetics sil- ver crucian carp(Carassius aurutus gibelio,1.0～1.5cm)was determined by conven- tional method.The results showed that pvidone-iodine semi-lethal mass concentrations on allogynogenetics silver crucian carp fry in 24 h,48 h ,96 h were 43.45,24.21,21.38 mg/L respectively,and its safe concentration was 2.14 mg/L;and that IO_3 semi-lethal mass concen trations on allogynogenetics silver crucian carp fry in 24 h,48 h ,96 h were 52.36,33.11,26.73mg/L respectively,and its safe concentration was 2.67 mg/L.
