水经氯化消毒后能增强其诱变性,在国内、外均有报导。某水厂拟用臭氧消毒替代氯消毒,我们在其试生产阶段对两种处理后饮水有机浓集物的诱变性作了初步检测。受检样品是将水样经GD×102树脂吸附,用乙醚洗脱,经浓缩挥干制备的。 一、氯化消毒后水质诱变性的检测 1.Ames试验:原水和净水均将有机浓集物折算为水样量,设0.13、0.32、0.8口2.0L/皿4组,外设阴性及阳性对照。检测结果原水各组均为阴性.氯化后净水对TA_(98)菌株在0.32L/皿时回变菌
Water chlorination disinfection can enhance its mutagenicity, both at home and abroad have been reported. A water plant intends to use ozone disinfection instead of chlorine disinfection, we conducted a preliminary test of the mutagenicity of two kinds of organic extracts of treated drinking water in its pilot production stage. The test sample is the water sample by GD × 102 resin adsorption, eluting with ether, evaporated to dryness by concentration. First, chlorinated water quality mutagenicity test 1.Ames test: raw water and water purification organic concentrates will be converted into water samples, set 0.13,0.32,0.8 mouth 2.0L / dish 4 group, peripherals negative And positive control. The test results were negative for each group of raw water after chlorination of water TA_ (98) strain 0.32L / dish when the bacteria
