聚维酮碘、硫酸铜及氯氰菊酯对漠斑牙鲆幼鱼的急性毒性试验

摘要

the author research the Acute toxicity tests of PVP -I ,cupric sulfate and cypermethrin on the ParalichthysLethostigma juveniles(70 d) In this study .The results showed that the safe concen‐tration of the PVP -I to ParalichthysLethostigma juveniles was 4 .062 mg/L ,the semi -lethal con‐centrations of 24 h was 55 .296 mg/L and 34 .560 mg/L was the semi-lethal concentrations of 48 h . The safe concentration ,of cupric sulfate was 0 .667 mg/L .the semi-lethal concentrations of 24 h was 2.812 mg/L and 2 .600 mg/L was the semi -lethal concentrations of 48 h .The safe concentration of effective cypermethrin was 0 .079 mg/L .Semi -lethal concentrations of 24 h was 7 .112 μg/L and 2.371 μg/L was its semi-lethal concentrations of 48 h .%研究了聚维酮碘、硫酸铜、高效氯氰菊酯三种药物在一定条件下对漠斑牙鲆幼鱼（70日龄）的毒性效应。结果表明：聚维酮碘的安全浓度为4．062 g／m L ；24 h半致死浓度为55．296 m g／L ，48 h半致死浓度为34.560 m g／L。硫酸铜的安全浓度为0．667 m g／L ，24 h半致死浓度为2．812 m g／L ，48 h半致死浓度为2．600 m g／L。高效氯氰菊酯的安全浓度为0．079μg／L ，24 h半致死浓度为7．112μg／L ，48 h半致死浓度为2．371μg／L。
