大气中的颗粒态有机硝酸酯是连接挥发性有机物（VOCs）、氮氧化物（NO_x）、二次有机气溶胶（SOA）及臭氧的关键物质，总结了近10年国内外对颗粒态有机硝酸酯来源、形成机制、测量分析方法、浓度水平等方面的研究，描述了现有大气化学框架下有机硝酸酯的大气转化机制，梳理了测量有机硝酸酯的离线、在线方法及其优缺点，总结了应用不同测量技术对环境大气中颗粒态有机硝酸酯的实测结果，提出了当前有机硝酸酯研究在测量技术、机理研究和观测尺度等方面的薄弱环节，并对其未来研究方向进行了展望.

Mechanism,measurement techniques and their application for particulate organonitrates

Particulate organonitrates are a key component connecting volatile organic compounds (VOCs), nitrogen oxides (NOx), secondary organic aerosols (SOA) and ozone formation. This study provides a thorough review on sources, formation mechanism, measurement techniques and ambient concentrations of particulate organonitrates based on previous studies for over a decade. A schematic diagram was given to illustrate the current knowledge of transformation mechanism for organonitrates in the atmosphere. We also listed current offline and online measurement techniques, associated with their advantages and disadvantages. Ambient mass concentrations of organonitrates in different field campaigns using mentioned measurement techniques were summarized. In addition, we point out the weakness of current organonitrates research and provide an outlook in future.
