中文摘要:

研究了戊二醛尧苯扎溴铵尧蛋氨酸碘及二溴海因等4 种消毒剂对方斑东风螺（Babylonia areolata）稚螺的急性毒性遥结果表明、毒性大小依次为苯扎溴铵>二溴海因>蛋氨酸碘>戊二醛、24 h半致死质量浓度（LC50）分别为 15.00尧39.95尧60.13尧91.88 mg/L；48 h LC50分别为7.59尧14.73尧32.02尧48.55 mg/L；安全浓度SC 分别为0.58尧0.60尧2.73尧 4.07 mg/L遥分析认为、在方斑东风螺的养殖过程中、推荐使用蛋氨酸碘、其在安全浓度以下可获得较好的消毒效果、戊二醛和二溴海因不推荐使用、苯扎溴铵应谨慎使用遥

英文摘要:

The acute toxicity of glutaraldehyde, benzalkonium bromide, iodine methionine and 1,3-Dibromo-5,5- Dimethylhydantoin (DBDMH) to juvenile Babylonia areolata was studied. The results showed that the order of toxicity was benzalkonium bromide>DBDMH>iodine methionine>glutaraldehyde, and the median lethal concentrations (LC50) of above disinfectants were 15.00 mg/L, 39.95 mg/L, 60.13 mg/L, 91.88 mg/L respectively in 24 h, and the LC50 were 7.59 mg/L, 14.73 mg/L, 32.02 mg/L, 48.55 mg/L, respectively in 48 h; and their SC (safe concentration) were 0.58 mg/L, 0.60 mg/L, 2.73 mg/L, 4.07 mg/L, respectively. We can use iodine methionine to disinfect B. areolata under safe concentration, but should not use glutaraldehyde and DBDMH, and can use benzalkonium bromide carefully.
