摘 要: | 为给水产养殖者在水产用药的选择、使用剂量和方法上提供参考依据,使水产用药更科学化,减少动物源性食品污染和环境污染,采用96h静态水试验方法,在pH值为8.02~8.37,溶氧量6.0mg/L,盐度20~24,水温(29.0±2.0)℃条件下,研究了三氯异氰尿酸、浓戊二醛、高碘酸钠、溴氯海因、次氯酸钠和苯扎溴铵6种常见渔药对体质量(4.3±0.5)g卵形鲳鲹的急性毒性。结果显示,三氯异氰尿酸、浓戊二醛、高碘酸钠和溴氯海因对卵形鲳鲹的24h半致死质量浓度分别为3.519、14.166、0.092mg/L和6.448mg/L,96h半致死质量浓度分别为3.434、12.936、0.083mg/L和6.150mg/L,安全质量浓度分别为0.981、4.018、0.025mg/L和1.812mg/L;次氯酸钠和苯扎溴铵的24h半数致死含量分别为2.156μL/L和9.806μL/L,96h半数致死含量分别为1.981μL/L和8.756μL/L,安全含量分别为0.529μL/L和2.666μL/L。试验结果表明,三氯异氰尿酸、浓戊二醛、溴氯海因在生产中正常使用的质量浓度下较为安全,高碘酸钠、次氯酸钠和苯扎溴铵需谨慎使用。

Abstract: | Acute toxicity of strong glutaral solution ,sodium periodate ,bromochlorohydantoin ,sodium hy‐pochlorite ,benzalkonium bromide and trichloroisocyanurie acid to golden pompano T rachinotus ov atus with body weight of (4 .3 ± 0 .5) g ,were studied in seawater filtered by sand ,at a pH of 8 .02—8 .37 ,dis‐solved oxygen level of above 6 .0 mg/L ,a salinity of 20—24 and water temperature of (29 .0 ± 2 .0) ℃ u‐sing 96 h static bioassay test .The results showed that the 24 h LC50 was 3 .519 mg/L in trichloroisocyanu‐rie acid ,14 .166 mg/L in strong glutaral solution ,0 .092 mg/L in sodium periodate ,6 .448 mg/L in bromo‐chlorhydantoin .2 .156 μL/L in sodium hypochlorite ,and 9 .806 μL/L in benzalkonium bromide ;The 96 h LC50 was 3 .434 mg/L ,12 .936 mg/L ,0 .083 mg/L ,and 6 .150 mg/L ,1 .981 μL/L ,8 .756 μL/L ;with the safe concentration of 0 .981 mg/L ,4 .018 mg/L ,0 .025 mg/L ,1 .812 mg/L ,0 .529 μL/L ,and 2 .666 μL/L .T he findings indicate that trichloroisocyanuric acid ,strong glutaral solution and bromochlorohydantoin are used safely in prodution ,but sodium periodate ,sodium hypochlorite ,benzalkonium bromide should be used caref ully . |
