摘要
随着城市化进程的加快,城市大气污染加剧给人类健康带来了一系列的危害。挥发性有机化合物(VOCs)组成复杂,二次生成物多,是形成光化学烟雾的重要前体物,已成为城市灰霾天气的主凶,而大多数挥发性有机物来自机动车辆、溶剂挥发和工业排放。该文综述了室外大气中挥发性有机物的组成,分析了这些挥发性有机物的产生原因,从时空分布和污染水平两方面阐述了大气中VOCs的污染特征。
With the rapid developroent of the urbanization in recent years, the air pollution in cities became more serious and it has brought a series of harms to the human＇s health. Volatile organic coropounds （VOCs） are very complex, and the secondary pollutant are abounding, they are the important precursors to form the photochemical smog, becoming the chief offender to the urban haze weather. The majority of VOCs are from motor vehicles, solvent evaporation and industrial emissions. The article summarized the main pollutant composition of VOCs in outdoor atmosphere, described the production reasons of VOCs, presented pollution characteristic in atmosphere VOCs from space-time distribution and pollution level.
