Abstract

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 PM_2.5 is close to their thermodynamic equilibrium concentrations.

比利时城乡大气中离子组成，相态和气溶胶的质量浓度的季节性变化（2001-2003年）

摘要

给出了比利时农村地区（Wingene）和城市地区（安特卫普）的气溶胶离子组成和质量浓度的现场数据，以及热力学分析的结果。发现硝酸铵和硫酸铵是气溶胶颗粒的主要水溶性组分。气溶胶颗粒的质量浓度，相态和离子组成的季节性变化在很大程度上取决于温度和相对湿度的变化。结果表明，PM _2.5中硝酸铵和硫酸铵的含量接近其热力学平衡浓度。
