The size distribution of total and water-soluble elemental concentrations in six particle sizes <0.49, 0.49-0.97, 0.97-1.5, 1.5-3.0, 3.0-7.2, and 7.2-30 μm was investigated in Thessaloniki area, N. Greece, at two sites representing urban-traffic and urban-background character during the cold and warm period. The elements As, Cd, Cr, Cu, Pb, Ni, Zn, Ru, and Ir exhibited their highest mass portion in the fine particle mode (0.97-1.5 μm), whereas Al, Ba, Ca, Fe, and Mn occurred predominately in the coarse particle mode (3.0-7.2 μm). The water-soluble elemental fractions exhibited significant spatiotemporal variations and particle size dependence. Possible non-carcinogenic and carcinogenic risks associated with inhalation of particle-bound elements based on total and water-soluble concentrations were in acceptable levels. However, the cumulative risk for all potential particle-bound constituents has to be considered.
在希腊北部塞萨洛尼基地区的两个具有城市交通和城市背景特征的地点，调查了冷温和温暖时期六个粒径<0.49、0.49-0.97、0.97-1.5、1.5-3.0、3.0-7.2 和 7.2-30μm 中总元素和水溶性元素浓度的颗粒分布。在细颗粒模式（0.97-1.5μm）中，As、Cd、Cr、Cu、Pb、Ni、Zn、Ru 和 Ir 等元素表现出最高的质量部分，而 Al、Ba、Ca、Fe 和 Mn 则主要出现在粗颗粒模式（3.0-7.2μm）中。水溶性元素部分表现出显著的时空变化和粒径依赖性。基于总浓度和水溶性浓度，与吸入颗粒结合元素相关的非致癌和致癌风险处于可接受水平。然而，必须考虑所有潜在的颗粒结合成分的累积风险。
