建立了大体积固相萃取?气相色谱?质谱／嗅辨同步分析方法，实现了实验室定性分析与人体嗅觉相结合的检测体系，用于地表水中半挥发性主要致味有机物质的鉴别．该方法能较为准确地判别地表水中0．312μg·L－1的硝基苯类、氯苯类、多环芳烃类物质的气味．采集有代表性的2个废水样品和6个地表水样品，结果表明，同步检测方法定性检出半挥发性主要致味有机物质气味与原始水样气味有显著相关性，但致味物质与污染物在水体的含量没有相关性．该方法为水体异味污染事故的鉴定提供方法借鉴，对水中异味物质的溯源具有指导作用．
An integrated method for the indentification of key semi?volatile odorous organic compounds in surface water was established by gas chromatography?mass spectrometry and olfactometry. Odorous compounds such as nitrobenzene, chlorobenzene and polycyclic aromatic hydrocarbon were tested accurately at the level of 0. 312 μg·L-1 . Two wastewater samples and six surface water samples were tested by this method. It was revealed that the main semi?volatile odorous organic compounds had a significant correlation with the odor of water samples, but not with the concentrations of pollutants in water. This method provides an alternative for the survey of environmental pollution accident, beneficial for the source tracing of odorous substances in water.
