摘要
城市灰尘 (urbandust)是指粒径小于 2 0目 ( <0 92 0mm) ,分散于城市不同区域 (位置、功能区 )的表面固体颗粒物。城市灰尘环境污染是指城市灰尘对城市环境所造成的污染。研究城市灰尘的目的是研究其物质来源、物质成分、分布规律、迁移演化、污染效应、防治治理等。文中论述了城市灰尘及其环境污染的科学定义、研究内容。
Urban dust is of surface solid grain scattering in different districts of urban (location and functional districts). Environmental pollution caused by urban dust means that urban dust pollutes urban environment. The purpose of researches on urban dust is focused on the source of dust material, composition of dust, distribution, migration and evolution, pollution effects and prevention and cure. This paper elucidates the scientific definition, research content and method of urban dust and environmental pollution.
