Outdoor aerosol particles were characterized in industrial area of Samalut city (El-minia/Egypt) using low pressure Berner cascade impactor as an aerosol sampler. The impactor operates at 1.7 m(3)/h flow rate. Seven elements were investigated including Ca, Ba, Fe, K, Cu, Mn and Pb using atomic absorption technique. The mean mass concentrations of the elements ranged from 0.42 ng/m(3) (for Ba) to 89.62 ng/m(3) (for Fe). The mass size distributions of the investigated elements were bi-modal log normal distribution corresponding to the accumulation and coarse modes. The enrichment factors of elements indicate that Ca, Ba, Fe, K, Cu and Mn are mainly emitted into the atmosphere from soil sources while Pb is mostly due to anthropogenic sources.
在埃及米尼亚省的萨马拉特市的工业区，使用低压伯纳尔级联冲击器作为气溶胶采样器对户外气溶胶颗粒进行了特征描述。冲击器以 1.7 m³/h 的流速运行。使用原子吸收技术研究了包括 Ca、Ba、Fe、K、Cu、Mn 和 Pb 在内的七种元素。这些元素的平均质量浓度范围从 0.42ng/m³（Ba）到 89.62ng/m³（Fe）。研究元素的质量尺寸分布呈双模态对数正态分布，对应于积累模态和粗模态。元素的富集因子表明，Ca、Ba、Fe、K、Cu 和 Mn 主要从土壤源排放到大气中，而 Pb 主要来自人为源。
