大气飘尘对人类生活环境有重要影响,其形状、粒径、比重、化学结合型等对人体的影响是个重大因素。飘尘的相对浓度(指各种元素)在时间和空间上的变化相对悬殊,各种因素(包括污染源、气候、气温、风向、风力、温度等)都会引起其浓度变化。目前国内外正在从各方面开展大气污染与
Atmospheric airborne dust has an important impact on human living environment, and its shape, particle size, specific gravity, and chemical combination are the major factors affecting the human body. The relative concentration of fly ash (referred to as various elements) is relatively variable in time and space. Various factors (including pollution sources, climate, temperature, wind direction, wind force, temperature, etc.) cause changes in concentration. Currently at home and abroad are from all aspects of air pollution
