Abstract

The mass size distribution of atmospheric aerosol particles was determinedby means of an electric low pressure impactor (ELPI) in rural air in Hungary. The particles captured on different stages of the impactor were chemically analyzed by capillary zone electrophoresis to quantify ionic componentsas well as by catalytic combustion method to detect total carbon in the samples. The results show that fine aerosol consists mainly of ammonium sulfate and organic carbon. These two species have rather different size distributions since very small particles are composed almost of carbon compounds. The analysis of fine aerosol samples collected simultaneously on filters indicates that an important part of organics is soluble in water. The mass balance of fine particles as a function of their size is estimated by taking into account the liquid water adsorbed by ammonium sulfate and by converting the mass of carbon to the mass of carbon compounds. Finally, the size resolved mass balance of fine aerosol particles is presented and discussed as a function of the origin of air masses. (C) 2001 Elsevier Science Ltd. All rights reserved.
