挥发性有机物(VOCs)是大气对流层重要的痕量组分,可通过光解和与OH自由基、NO3自由基、O3的化学反应过程而发生迁移转化.随着人类活动的加剧,VOCs在对流层大气化学中的作用越来越重要.本文总结了大气中 VOCs(包括烷烃、烯烃、芳香烃、含杂原子的 VOCs)与 Ox、HOx、NOx的气相反应和它们大气降解过程的研究进展,分析了VOCs在臭氧和气溶胶形成中的定性和定量作用,进而展望了VOCs对流层大气化学研究前景.

Volatile organic compounds (VOCs) are very important trace constituents of the troposphere. They can be transformed by photolysis and the chemical reactions with hydroxyl (OH), nitrate (NO3) radical and O3. With the severity of human activity, VOCs play a critical role in the atmospheric chemistry. This paper presents gas-phase reactions of selected classes of volatile organic compounds (alkanes, alkenes, aromatic hydrocarbons, halogen-containing, oxygen-containing and nitrogen-containing VOCs) with HOx, NOx and Ox species and the research progresses of their chemical degradation in the troposphere. The qualitative and quantitative roles of VOCs in the formation of ozone and aerosol are analyzed. The prospects of tropospheric chemistry of VOCs are described.
