饮用水中挥发性卤代烃是由天然水中的腐殖质与消毒剂共同作用产生,水源水受到工业或医药废水的污染时,也可导致饮用水中挥发性卤代烃的增加[1-2]。三卤甲烷(三氯甲烷、二氯一溴甲烷、一氯二溴甲烷、三溴甲烷)和四氯化碳具有致畸、致癌、致突变性[3-4],且难以进行微生物降解和光化学降解,可通过呼吸、皮肤接触或饮水进入人体,对人体健康造成危害[5]。三卤甲烷和四氯化碳等挥发性卤代烃是
Volatile halogenated hydrocarbons in drinking water are produced by the combined action of humic substances and disinfectants in natural water, which can also lead to an increase in volatile halogenated hydrocarbons in drinking water when they are contaminated by industrial or medical wastewaters [1-2] . Trihalomethanes (trichloromethane, dichlorobromomethane, chlorodibromomethane, tribromomethane) and carbon tetrachloride have teratogenic, carcinogenic, mutagenic [3-4], and difficult to carry out microbial degradation and photochemical degradation, Through breathing, skin contact or drinking water into the human body, causing harm to human health [5]. Volatile halogenated hydrocarbons such as trihalomethanes and carbon tetrachloride are
