In this study, Xuzhou, a typical industrial city in the north of Jiangsu Province, was chosen to investigate the pollution level of atmospheric particulates. The proportion of fine particles (PM) in PM is larger than that of coarse particles (about 58%). The physicochemical properties of PM were analyzed by SEM and EDS. DGGE was used to study the distribution characteristics of bacterial community structure on atmospheric particulates (TSP, PM and PM) in different functional areas of Xuzhou city during the winter haze. It was found that the microbial populations of atmospheric particles were mainly divided into three groups: . The community structure of bacteria in fine particle size was more abundant than that in coarse particle size. When haze occurs, the concentration of all kinds of pathogens in fine particle size will increase. Therefore, it is necessary to focus on the monitoring and management of fine particles.
在这项研究中，选择了江苏省北部的典型工业城市徐州，以调查大气颗粒物的污染水平。细颗粒物（PM）中细颗粒（PM）的比例大于粗颗粒（约 58%）。通过 SEM 和 EDS 分析了 PM 的理化性质。通过 DGGE 研究了徐州市不同功能区冬季雾霾期间大气颗粒物（TSP、PM 和 PM）上细菌群落结构的分布特征。结果表明，大气颗粒物中的微生物种群主要分为三组：。细颗粒中细菌的群落结构比粗颗粒丰富。当发生雾霾时，细颗粒物中各种病原体的浓度都会增加。因此，有必要重点监测和管理细颗粒物。
