    Source Apportion of Atmospheric PM10 and PM2.5 in Donghe District of Baotou

      Graphical Abstract
      • Abstract
    • Objectives  To study the source apportion of atmospheric PM10 and PM2.5 in Donghe district in Baotou.
      Methods  Atmospheric particle samples for PM10 and PM2.5 were collected in Donghe district in Baotao from April 27th to June 5th in 2006. Chemical elements in aerosol samples were detected and the data were calculated by factor analysis and enrichment factors.
      Results  The source apportion results for PM10 derived from factor analysis model were construction dust/soil dust/vehicle emissions (29.44%), soil dust (27.17%) and industry dust (20.36%); for PM2.5 were construction dust/soil dust (54.03%) and industry dust/coal combustion (29.98%) in Donghe district in Baotou. Enrichment factors for heavy metals (such as As、Zn、Pb、Cd) in PM2.5 were higher than those in PM10 in sand-dusty weather or non-sand-dusty weather.
      Conclusions  The pollution of PM10and PM2.5 in Donghe district in Baotou are mainly from natural sources and combined sources from industrial dusts and coal combustion.
