The urban atmosphere is characterised by a multitude of complex processes. Gaseous and particulate components are continuously emitted into the atmosphere from many different sources. These components are then dispersed in the urban atmosphere via turbulent mixing. Numerous chemical reactions modify the gas phase chemistry on multiple time scales, producing secondary pollutants. Through partitioning, the chemical and physical properties of the aerosol particles are also constantly changing as a consequence of dispersion and gas phase chemistry. This review presents an overview of the involved processes, focusing on the contributions presented at this conference and putting them into a broader context. Advanced methods for aerosol source apportionment are presented as well, followed by some aspects of health effects related to air pollution.
城市大气具有多种复杂的过程。气态和颗粒成分从许多不同来源持续排放到大气中。然后这些成分通过湍流混合在城市大气中扩散。众多化学反应在多个时间尺度上改变气相化学，产生二次污染物。通过分配，气溶胶颗粒的化学和物理性质也因扩散和气相化学而不断变化。本综述概述了所涉及的过程，重点关注本次会议上提出的贡献并将其置于更广泛的背景中。还介绍了气溶胶源解析的先进方法，随后是与空气污染相关的健康影响的一些方面。
