常用消毒剂戊二醛对金鱼的急性毒性实验

Common Aquatic Glutaraldehyde Disinfectants on Goldfish Acute Toxicity

摘要: 利用在一定的控制条件下(一定的温度、pH、盐度、溶氧等)，不同浓度的常用水产消毒剂(戊二醛)做对金鱼(短尾金鲫型)的急性毒性试验。做戊二醛浓度–死亡百分率的标准曲线，可得戊二醛对金鱼的24 h，48 h半致死浓度分别为0.84 ml/l和0.73 ml/l。而其安全浓度在0~0.21 ml/l，0~0.20 ml/l，与日常消毒使用量相符。

Abstract: Acute toxicity tests on goldfish (short-tailed golden carp type) were conducted using common aquatic disinfectants (glutaraldehyde) of different concentrations under certain control conditions (such as certain temperature, pH, salinity, dissolved oxygen, etc.). By using the standard curve of glutaraldehyde concentration-mortality percentage, it can be obtained that the semi-lethal concentrations of glutaraldehyde for goldfish at 24 hours and 48 hours are 0.84 ml/l and 0.73 ml/l respectively. Its safe concentration ranges from 0 to 0.21 ml/l and 0 to 0.20 ml/l, which is consistent with the daily disinfection usage amount.
