中文摘要: |
研究了戊二醛、二溴海因、蛋氨酸碘和次氯酸钙等4 种消毒剂对大珠母贝(Pinctada maxima)
幼贝的急性毒性,结果表明,毒性大小依次为次氯酸钙> 二溴海因> 蛋氨酸碘> 戊二醛,24 h 半致死质量
浓度(LC50)分别为13.05、27.49、53.20、67.36 mg/L,48 h LC50 分别为10.15、9.35、29.27、35.58 mg/L,安全
浓度SC 分别为1.86、0.32、2.66、7.52 mg/L。分析认为,由于戊二醛毒性相对较小,且在其安全浓度以下可
获得较好的消毒效果,因此在大珠母贝幼贝的养殖过程中,推荐使用戊二醛作为常用消毒剂,二溴海因和
蛋氨酸碘应谨慎使用,次氯酸钙不推荐使用。 |
英文摘要: |
The acute toxicity of glutaraldehyde,dibromohydantoin,methionine iodine and calcium hypochlorite
to juvenile Pinctada maxima was studied. The results showed that the order of toxicity was calcium hypochlorite>
dibromohydantoin> methionine iodine> glutaraldehyde,and the median lethal concentrations( LC50) of above
disinfectants were 13.05 mg/L,27.49 mg/L,53.20 mg/L and 67.36 mg/L respectively in 24h,and the LC50 were
10.15 mg/L,9.35 mg/L,29.27 mg/L and 35.58 mg/L respectively in 48h;and their SC( safe concentration) were 1.86
mg/L,0.32 mg/L,2.66 mg/L and 7.52 mg/L respectively. We can use glutaraldehyde to disinfect P. maxima under
safe concentration,but should not use calcium hypochlorite,and can use dibromohydantoin and methionine iodine
carefully. |
