沈阳市大气颗粒物分布规律及影响因素研究
|
摘要
受工业化和城市化的影响,城市内部颗粒物排放源增多,城市空气颗粒物污染越来越严重,已经成为全社会关注的焦点。颗粒物是造成大气空气质量下降的主要污染物,而且会对人类身体健康产生危害。针对当前空气污染日趋严重、雾霾天气频发的现状,本实验针对可吸入颗粒物的重要释放源之一——汽车尾气的排放对可吸入颗粒物浓度的影响做了深入研究,旨在寻找它们之间的相关性,为雾霾天气的来源解析做理论基础研究。
Due to the influence of industrialization and urbanization, the increase of particulate matter sources within the city and the pollution of urban airborne particulate matter have become the focus of attention of the whole society. Particulate matter is the main pollutant causing the deterioration of atmospheric air quality, and it is harmful to human health. In view of the current situation of increasingly serious air pollution and frequent smog weather, this experiment has conducted in-depth research on the influence of vehicle exhaust emission, one of the important sources of release of inhalable particulate matter, on the concentration of respirable particulate matter. The correlation is a theoretical basis for the source analysis of haze weather.
