摘　　要：以北京市10家不同规模和类型的室内泳池的池水和6个不同地区的水龙头水为研究对象,分析确定我国室内泳池水和自来水中以三氯甲烷、氯乙酸和二氯乙腈为代表的氯消毒副产物的实际存在状况,同时比较了两种前体物(天然有机物和人体代谢物)生成三氯甲烷和氯乙酸的潜力。结果表明,室内泳池水中三氯甲烷、氯乙酸、二氯乙腈的平均值分别为29.2、79.4、1.31μg/L,自来水的平均值分别为23.7、4.6、0.22μg/L。在相同的条件下,人体代谢物加氯后生成的氯乙酸浓度高于三氯甲烷,而天然有机物的生成趋势则相反,印证了以人体代谢物为主要前体物的室内泳池水和以天然有机物为主要前体物的自来水中消毒副产物的生成情况有所差异的结论。Water from 10 indoor swimming pools with different sizes and types and tap water from 6 different areas in Beijing were investigated to analyze the occurrence of chlorinated disinfection byproducts （ trichloromethane, chloroacetic acid and dichloroacetonitrile） in domestic indoor swimming pool water and tap water. Trichloromethane and chloroacetic acids formation potential of two types of precursors （ natural organic matter and human body excretion） were compared at the same time. Results showed that average concentrations of trichloromethane,chloroacetic acid and dichloroacetonitrile in indoor swimming pool water were 29.2, 79.4 pg/L and 1.31 pg/L,respectively,and in tap water were 23.7, 4.6 pg/L and 0.22 p g /L,respectively. Under the same condition, human body excretion showed higher potential to form chloroacetic acid than to form trichloromethane, while natural organic matter exhibited the opposite formation potential. These findings confirmed the conclusions that disinfection by-products were different in indoor swimming pool water and tap water,where the main precursors were human body excretion and natural organic matter, respectively.
