Research progress of PM2.5 source analysis in three main regions of China
Translated Abstract
At present,PM2.5 concentration in many provinces and cities in China are over the standard value,which is particularly serious in the regions with the leading level of economic development,such as Beijing-Tianjin-Hebei Region,Yangtze River Delta and Pearl River Delta.The sources of PM2.5 have attracted great attentions in all sectors of society.By analyzing the related literatures about different cities in different regions and combining with the latest source analysis results published by environmental protection administration,the PM2.5 source analysis in three key regions mentioned above is compared and discussed.The results show that among the three key areas,vehicle emission is the primary source of pollution in Beijing,Shanghai,Hangzhou,Guangzhou and Shenzhen.For second and third tier cities,PM2.5 sources are mainly coal-fired fly ash and dust pollution.Therefore,to reduce the pollution of PM2.5,reduction of the vehicle emission is the urgent task,which is also suggested to combine with the control of coal-fired fly ash and dust pollution.Finally,the further development directions of PM2.5 source analysis are proposed,which is expected to serve a reference for formulation of feasible policy measures to reduce the pollution of PM2.5.
