摘　　要：挥发性有机物(VOCs)是臭氧及二次有机颗粒物(SOA)的主要前体物。近年来,我国逐步将VOCs纳入大气污染物控制体系。准确可靠的监测技术是大气VOCs研究及控制的重要前提保障。按照采样方法、分析方法 2个方面介绍并讨论了城市大气中VOCs的现有监测方法,较为详细地介绍了几类广泛采用的离线及在线监测技术,简要讨论了目前VOCs监测中存在的一些问题,展望了今后的发展趋势。Volatile organic compounds （VOCs） are precursors of ground-level 03 and secondary organic aerosol （SOA）. The VOCs emission control has been one of the key components in national and local clean air programs. The accurate measurement of VOCs is essential for research as well as emission control of VOCs. A review on current measurement techniques of ambient VOCs in urban atmosphere was performed and several widely-used offline and online VOCs measurement techniques including sampling and analysis methods were summarized. Also the major problems of ambient VOCs measurement were identified with an outlook of the further trend.
