摘要
为了检测戊二醛和苯扎溴铵两种消毒剂对中华鰟鮍疾病防治的效果,采用半静水式生物测试法测定了戊二醛和苯扎溴铵对中华鰟鮍的急性毒性效应。结果表明:戊二醛(含量25%)对中华鰟鮍24h、48h、72h和96h的LC50分别为110.40μL/L、81.29μL/L、73.28μL/L和70.80μL/L,安全浓度为13.22μL/L;苯扎溴铵(含量45%)对中华鰟鮍24h、48h、72h和96h的LC50分别为5.23μL/L、4.69μL/L、4.22μL/L、3.93μL/L,安全浓度为1.13μL/L。戊二醛对中华鰟鲏为低毒药物,苯扎溴铵为中等毒性药物,二者的常用浓度均低于安全浓度,适合作为中华鰟鲏疾病防治的药物。
The acute toxicity of two kinds of disinfectants (glutaraldehyde and benzalkonium bromide) were tested with R. sinensis. The results showed that the 24 h, 48 h, 72 h and 96 h LCs0 of glutaraldehyde (content of 25%) were 110.40μL/L,81. 29μL/L,73. 28 μL/L and 70. 80 ~L/L respectively, and the safety concentration was 13.22μL/L. And thatof benzalkonium bromide(content of 45%) were 5.23μL/ L,4.69 /μL/L,4.22 μL/L. and 3.93 μL/L,separately. And the safety concentration was 1.13 μL/L. This indicated glutaraldehyde was low-toxic disinfectant and benzalkonium bromide was middle-toxic for R. sinensis. The safety concentrations of the two disinfectants were lower than that in common use. As a consequence disinfectants of glutaraldehyde and benzalkonium bromide were safe for R. sinensis.
