Characteristics and Source of the Atmospheric Fine Particles and Secondary Inorganic Compounds at Mount Dinghu in Autumn Season
鼎湖山秋季大气细粒子及其二次无机组分的污染特征及来源

Real-time measurements of PM2.5,secondary inorganic compounds in PM2.5(SO2-4,NH+4,and NO-3) and related gaseous pollutants were conducted at Mount Dinghu,a regional background station of the Pearl River Delta(PRD),in October and November 2008 by using a conventional R&P TEOM and a system of rapid collection of fine particles and ion chromatography(RCFP-IC).Sources and transportation of atmospheric particles during the experiment were discussed with principal component analysis and backward trajectories calc...
