摘　　要：臭氧(O_(3))作为典型的二次污染物,已成为国内大多数城市的首要大气污染物,挥发性有机物(VOCs)是生成O_(3)的关键前体物,而机动车尾气是最主要的人为VOCs排放源。目前,已有众多研究探讨了机动车尾气的VOCs排放特征,但不同VOCs组分的O_(3)的生成贡献尚不明晰。在对各研究中不同影响因素下机动车尾气的VOCs组成进行系统梳理的基础上,得出尾气VOCs对O_(3)的生成贡献及O_(3)生成优势物种,旨在为O_(3)污染防治措施的制定提供一定的数据参考及理论支撑。Ozone which is a typical secondary pollutant has become the primary atmospheric pollutant in most cities in our country.Volatile organic compounds(VOCs)are the key precursor to ozone generation.And vehicle emission is the most important source of man-made VOCs emissions:At present,many studies have explored the characteristics of VOCs emissions from vehicle exhaust,but the contribution of different VOCs components to ozone generation is not clear.On the basis of systematically combing the composition of VOCs under different influence factors in the current research,the ozone generation contribution of VOCs and the dominant species of ozone generation were proposed,aiming to provide data reference and theoretical support for the formulation of ozone pollution prevention measures.
