摘  要:
在水温25-26℃、pH 7.8-8.4和盐度31的条件下,采用静水式试验,探讨强氯精、高锰酸钾、甲醛、二溴海因和聚维酮碘5种消毒药物对管角螺幼螺的急性毒性作用。结果表明,强氯精对管角螺幼螺24h、48h的LC_(50)分别为67.3mg/L和31.6mg/L,高锰酸钾24h、48h的LC_(50)分别为206mg/L和83.1mg/L,甲醛24h、48h的LC_(50)分别是87.0mg/L和54.9mg/L,二溴海因24h、48h的LC_(50)分别为302mg/L和231.2mg/L,聚维酮碘24h、48h的LC_(50)分别为3234mg/L和1472.3mg/L;其对管角螺幼螺的安全质量浓度分别为:2.09mg/L、3.90mg/L、6.56mg/L、40.65mg/L和91.54mg/L。这5种药物对管角螺幼螺的毒性大小依次为:强氯精>高锰酸钾>甲醛>二溴海因>聚维酮碘。

摘  要:
The acute toxicities of five common drugs to juvenile Hemifusus tuba was studied at water temperature of 25-26℃,pH 7.8~8.4 and salinity 31‰ by a static test method.It was found that the median-lethal concentrations(LD50)of Trichloroisocyanuric acid(TCCA)was 67.3 mg/L in 24 h,31.6 mg/L in 48 h.The LD50 of KMnO4 was 206 mg/L in 24 h,83.1 mg/L in 48 h.The LC_(50) of HCHO was 87 mg/L in 24 hand 54.9 mg/L in 48 h.The LC_(50) of MBDMH was 302 mg/L in 24 hand 231.2 mg/L in 48 h.The LC_(50) of PVP-I was 3234 mg/L in 24 hand 1472.3 mg/L in 48 h.Safe concentration(SC)of five disinfectants are 2.09 mg/L,3.90 mg/L,6.56 mg/L,40.65 mg/L and 91.54 mg/L,respectively.The result showed that the acute toxicity order of the five pesticides to juvenile H.tuba was ranged as TCCA>KMnO4>HCHO>MBDMH>PVP-I.It is recommended that KMnO4,HCHO and TCCA can be used carefully,while MBDMH and PVP-I are proposed to be ideal disinfectant in the breeding and disease control of H.tuba.
