The PM_2.5 Pollution Prevention Countermeasures Study In Harbin

this paper detailed expounds the atmospheric particulate matter PM2.5in the concept, classification, basic characteristics, sources, hazard effects and spatial distribution characteristics of PM2.5and the time change characteristics, summarizes the forming mechanism and source of PM2.5parsing techniques, sampling method and component analysis methods, and points out the domestic and foreign research status and progress trend of PM2.5atmospheric particulate matter in the future research related areas to provide a reliable basis. At the same time, the atmospheric particulate matter pollution condition in Harbin, the source of atmospheric fine particles (PM2.5) parsing and space-time distribution is analyzed, and for special climate environment of Harbin air fine particles pollution effective prevention countermeasures are put forward.
