摘　　要：运用吹扫捕集和气相色谱-质谱联用技术对南京市8个自来水厂生产的生活饮用水中挥发性有机化合物进行了分析研究,共检出化合物20种,主要是由液氯消毒带来的副产物挥发性卤代烃,检出化合物的量都低于国家饮用水标准,亦即南京市饮用水中挥发性有机物含量符合饮用标准。Volatile organic compounds （VOCs） in drinking water samples from eight water supply works of Nanjing city were trapped through purging and investigated by gas chromatographymass spectrometry, twenty VOCs including volatile halogenated hydrocarbons, volatile monoaromatics, naphthalene and volatile halogenated benzenes were detected. The pollution level of all detected VOCs was below the permissible concentration specified by the national drinking water standard, which indicated that the VOCs concentration in Nanjing drinking water was in compliance with the drinking water quality standard.
