The present study focuses on the simultaneous analysis of metallic species and radionuclide data from January 2009 to December 2011 in the dust deposited on filters in Málaga (Spain). Some metallic elements (Ca, Fe, K, Mg, Na, Zn, Pb, Cu, Ni) and radionuclides (⁷Be and ²¹⁰Pb) have been determined by inductively coupled plasma-mass spectroscopy and gamma spectrometry, respectively. For this analysis, daily variation of PM₁₀ mass concentration was additionally recorded at the nearest station belonging to the regional atmospheric pollution monitoring network. The comparison between ²¹⁰Pb, elemental lead, and PM₁₀ mass concentration reveals a different time variation for raining months, and an increase in the ²¹⁰Pb/Pb ratio indicates local sources of the particulate mass. Principal components analysis (PCA) applied to the datasets and calculation of enrichment factors relative to soil and seawater reveal that the atmospheric aerosol chemistry in this area of the Mediterranean is mostly influenced by crustal and marine sources rather than anthropogenic ones.

马拉加（西班牙）大气气溶胶中微量金属和放射性核素的临时变化和来源

本研究的重点是对2009年1月至2011年12月沉积在西班牙马拉加的过滤器上的粉尘中的金属种类和放射性核素数据进行同时分析。某些金属元素（Ca，Fe，K，Mg，Na，Zn，Pb，Cu，Ni）和放射性核素（⁷ Be和²¹⁰ Pb）已分别通过电感耦合等离子体质谱和伽马能谱测定。为了进行此分析，另外在属于区域大气污染监测网络的最近站点记录了PM ₁₀质量浓度的每日变化。²¹⁰ Pb，元素铅和PM ₁₀质量浓度之间的比较表明，下雨月份的时间变化不同，²¹⁰ Pb / Pb比表示颗粒物的局部来源。主成分分析（PCA）应用于数据集和相对于土壤和海水的富集因子的计算表明，地中海地区的大气气溶胶化学主要受地壳和海洋资源的影响，而不是人为的。
