大气气溶胶化学分子式：CAS号：性质：又称大气气溶胶化学（atmospheric aerosol chemistry）；大气颗粒物化学（atmospheric particulate chemistry）。大气化学的分支之一。主要研究大气中气溶胶（又称颗粒物）的来源、形成、分布、传输及消除过程中的物理、化学行为，化学组成的变化，存在状态的特性、粒度分布的特性及其与大气现象的关系等。许多大气污染现象都直接或间接与气溶胶的物理化学特性和行为有关。例如，燃烧化石燃料或光化学烟雾反应会产生硫酸盐气溶胶（一次或二次颗粒物），它对环境会引起酸化，并能远距离迁移，造成广域污染；美国东北部和五大湖地区出现的酸雨危害，就是典型例子。气溶胶在不同粒度中的化学组成不同，对环境影响和生态效应也大不相同。伦敦烟雾事件中因有气溶胶的存在而使危害加剧。小于2μm粒径气溶胶中集中了绝大多数的有毒有害物质，在大气中滞留时间长、传输广，危害大。气溶胶化学涉及非均相大气化学反应和颗粒表面反应等问题，气溶胶对气候有变冷的效应（或称阳伞效应），这些都是当今气溶胶化学关注的问题。
