中文摘要 |
MX[3-氯-4-(二氯甲基)-5-羟基-2(5H)-呋喃酮]是饮用水氯化消毒过程中产生的具有强致突变作用的副产物.实验利用XAD-8吸附树脂对江苏省癌症高发区自来水中的MX进行了富集,饱和BF3-CH3OH溶液衍生化,并用GC/MS测定.结果发现,除个别点MX含量较高外,其余浓度在0.58~20.0ng·L-范围之内.同一采样点枯水期浓度要高于平水期. |
英文摘要 |
MX [3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone] was found to be the most potent mutagen in chlorinated drinking water. MX in some tap waters in Jiangsu Province was absorbed by XAD-8 resin, methylized with saturated BF3-CH3OH and detected using GC/MS. The contents of MX in the tap waters were between 0.58 to 20.0ng·L-, except one of those samples. More MX was produced in low water season. |
