摘要
近年来,随着经济的迅速发展和城市化进程的加快,灰霾天气呈现增加的趋势,引起了社会的高度关注。综述了灰霾发生时大气颗粒物污染水平、粒径分布和垂直分布特征,大气颗粒物重要化学成分(水溶性离子、有机碳和元素碳、金属元素)的浓度水平和粒径分布特征及大气颗粒物的来源解析方法,并提出灰霾主要防治措施。
In recent years,with the rapid development of economy and the speeding up of urbanization,the haze weather shows increasing trend and causes the attention of the society. The contamination level,size distribution and vertical distribution of atmospheric particulate matter during the haze period were introduced,the concentration level and the size distribution of water- soluble ions,organic and elemental carbon and metal elements in the atmospheric particulate matter were described,and the source analysis methods of atmospheric particulate matter were summarized.Some advices on the prevention and control measures of the haze weather were proposed.
