指出了挥发性有机物（VOCs）是对流层臭氧（O3）和二次有机气溶胶（SOA ）等二次污染的重要前体物，其污染问题已经引起了国内外学者的广泛关注。通常采用羟基（OH）消耗速率和臭氧生成潜势（OFP）表征VOCs的大气反应活性，VOCs的关键活性组分主要有芳香烃中的二甲苯、甲苯、乙苯以及C2到C5的烯烃；采用FAC估算法和有机碳/元素碳（OC/EC）比值法来估算 VOCs对SOA生成的贡献，SOA的主要前体物有萜烯和芳香烃；采用VOCs/NOX 比值定性分析大气中O3浓度与NOX 和VOCs的关系，国内外城市O3的生成对VOCs和NOX 浓度的变化敏感性不一致。基于国内外大气中挥发性有机物（VOCs ）光化学行为的研究动态，阐述了环境空气中VOCs的大气反应活性、二次有机气溶胶（SOA ）的生成贡献以及与NOX 、O3的关系，为VOCs、细粒子以及O3污染的控制提供科学依据。

Volatile organic compounds(VOCs)is an important precursor of tropospheric ozone and secondary organic aerosol ,whose pollution problem has attracted wide attention of scholars at home and abroad .Usual-ly ,OH radical loss rate and the ozone formation potential (OFP) are applied to assess the chemical reactivity of VOCs .The key reactive species arexylene ,toluene ,ethylbenzene and C2-C5 alkene .Fractional aerosol co-efficients (FAC) and the ratio of organic carbon and element carbon (OC/EC) are used to estimate the po-tential formation of secondary organic aerosols (SOA) .The SOA precursors contain terpene and aromatics . The ratio ofVOCs to NOx (VOCs/NOx) is used to analyze the relation between O3 and NOx ,VOCs qualita-tively ,which is abhorrent .Based on the researches of atmospheric VOCs photochemical behavior ,this article reviews the studies of chemical reactivity of VOCs ,potential formation of SOA and the relation between O3 and NOx ,VOCs so as to provide a scientific basis for VOCs ,particles and O3 pollutioncontrol .
