摘要
为探明高锰酸钾、聚维酮碘、二氧化氯和聚六亚甲基胍对岩虫的毒性效应及安全浓度,采用常温半静水试验法,开展了这4种消毒药物对岩虫的急性毒性试验。结果表明:岩虫对4种药物的耐受力为10%聚维酮碘>高锰酸钾>10%二氧化氯>25%聚六亚甲基胍。10%聚维酮碘对岩虫的24、48、96 h半致死质量浓度分别为418.41、242.67、89.49 mg·L^(-1),安全质量浓度为8.95 mg·L^(-1);高锰酸钾对岩虫的24、48、96 h半致死浓度分别为14.10、9.59、7.38 mg·L^(-1),安全质量浓度为0.74 mg·L^(-1);10%二氧化氯对岩虫的24、48、96 h半致死浓度分别为89.26、47.18、4.61 mg·L^(-1),安全质量浓度为0.46 mg·L^(-1);25%聚六亚甲基胍对岩虫的24、48、96 h半致死浓度分别为11.44、3.08、1.13 mg·L^(-1),安全质量浓度为0.11 mg·L^(-1)。在岩虫育苗和养殖生产中,聚维酮碘和二氧化氯的使用是适宜的,聚六亚甲基胍和高锰酸钾应当谨慎使用。
In order to explore the toxic effect and safe concentration of potassium permanganate,povidone iodine,chlorine dioxide and polyhexamethylene guanidine on Marphysa sanguinea,the acute toxicity test of these four disinfectants on M.sanguinea was carried out by using the semi-hydrostatic test at room temperature.The results showed that the tolerance capability of M.sanguinea to the four kinds of disinfectants was 10% povidone iodinepotassium permanganate10% chlorine dioxide25% polyhexamethylene guanidine.The 24 h,48 h and 96 h median lethal concentrations of 10% povidone iodine were 418.41,242.67 and 89.49 mg·L~(-1),respectively,and the safe concentration was 8.95 mg·L~(-1).The 24 h,48 h and 96 h median lethal concentrations of potassium permanganate were 14.10,9.59 and 7.38 mg·L~(-1),respectively,and the safe concentration was 0.74 mg·L~(-1).The 24 h,48 h and 96 h median lethal concentrations of 10% chlorine dioxide were 89.26,47.18 and 4.61 mg·L~(-1),respectively,and the safe concentration was 0.46 mg·L~(-1).The 24 h,48 h and 96 h median lethal concentrations of 25% polyhexamethylene guanidine were 11.44,3.08 and 1.13 mg·L~(-1),respectively,and the safe concentration was 0.11 mg·L~(-1).The use of povidone iodine and chlorine dioxide was suitable in the breeding and culture production of M.sanguinea,while polyhexamethylene guanidine and potassium permanganate should be used with caution.
