摘　　要：大气中的污染物种类繁多,来源和演化过程复杂,而且污染物之间在一定的条件下发生相互作用,形成一种彼此耦合的复杂污染体系,被称为复合污染。为了研究大气复合污染的形成原因及其控制手段,必然要求对各种大气污染的主要物种浓度进行测量,特别是超细粒子、有机气溶胶和挥发性有机物组分复杂,对检测技术要求较高。介绍了针对大气复合污染的新型观测技术,综述了以下3项技术的发展:超细气溶胶颗粒物观测新技术、气溶胶有机物组分分析新技术和挥发性有机物分析新技术,同时综述了大气复合污染的其他监测手段。Air pollution consists of a large number of pollutants, which usually have complicated sources and aging pathways.There are interactions among these pollutant species, thereby forming so called combined pollution. To study the formation mechanism and control technology for air pollution, it is necessary to measure the concentrations of major pollutants in the air.However, ultrafine aerosol particles, organic aerosols and volatile organic compounds are especially difficult to detect. This paper introduces the new technologies and methods for measuring air pollutants. Specifically, the recently developed methods for measuring ultrafine aerosol particle formation, volatile organic compounds, and particulate organics are discussed in detail.Besides, a short review of other widely used monitoring methods is also included.
