Seasonal Variability of the Ion Composition, Phase State,and Mass Concentration of Aerosol in the Rural and Urban Atmosphere over Belgium (2001–2003)
2020
Field data on the ion composition and mass
concentration of aerosol in the rural (Wingene) and urban (Antwerp)
regions of Belgium and the results of their thermodynamic analysis are
presented. Ammonium nitrate and ammonium sulfate are found to be the
major water-soluble components of aerosol particles. The seasonal
variability of mass concentration, phase state, and ion composition of
aerosol particles is largely determined by variations in temperature and
relative humidity. It is shown that the content of ammonium nitrate and
ammonium sulfate in PM2.5 is close to their thermodynamic
equilibrium concentrations.
