由于城市水源水和自来水多受到有机诱变物和致癌物的污染,对水的致突变性的检测国内外已不断有报告。目前进行水的致突变性检测,多采用XAD_2树脂来吸附水中有机污染物。作者对XAD_2树脂吸附已知直接和间接诱变剂,并用二甲亚砜以及不同溶剂的洗脱效果进行了观察比较。 As urban source water and tap water are mostly contaminated by organic mutagens and carcinogens, the detection of the mutagenicity of water has been continuously reported at home and abroad. At present, the mutagenicity of water is tested, and XAD 2 resin is often used to adsorb organic pollutants in water. The authors adsorbed known direct and indirect mutagens on XAD_2 resin, and observed and compared the elution effects of dimethyl sulfoxide and different solvents.
