摘要
大气气溶胶细颗粒物 (PM1 0 、PM2 5)是近年来大气气溶胶研究的热点。细粒子中含有多种化学元素与化合物。细粒子中的化学成分随时空变化而变化。细粒子主要来自车辆尾气、化石、油料及生物质燃料燃烧等人为排放源和二次污染。
Fine particles in atmospheric aerosols(PM 10, PM 2.5) are a key of study on atmospheric aerosols in recent years. There are multiple of chemical elements and compounds in fine particles. The chemical elements would change with spatial and temporal variability in fine particles. It is found that the fine particles come mainly from vehicle exhausts, fossil, oil-bearing and biomass fuel combustion made by mankind and secondary polluted products in atmosphere.
