The results presented in this work demonstrate for the first time a distribution of elements in the spectral analysis of aerosols in the suburban continental Balkan Peninsula. Samples were collected in the suburban area of Belgrade (Serbia) in the period from March 2012 till December 2013. Results presented here are from long-term measurements of masses of size-segregated aerosols and macro- and microelements in the range of PM. The following elements were analyzed: Al, Ag, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Ti, Tl, V, and Zn; levels of Be, Hg, and Se were under the detection limits in all samples. Average concentrations and time and seasonal variations of particulate matter (PM) as well as element contents and their percentage shares are given. The results showed the domination of particle content around the accumulation mode in the range of 0.53 < Dp < 1.06 μm, but the fractional distribution of elements showed maximal average concentrations in different fractions depending on the origin of each element. Crustal elements (Al, Ca, Fe, Mg, Mn, Ti, etc.) dominated in coarse mode, while anthropogenic elements (As, Cd, Cu, Pb, Sb, etc.) were mainly distributed in fine mode fractions. Some elements, such are As and Ni, were detected in investigated aerosols only occasionally, while others, such as Ca, Fe, and Mg, were detected in all analyzed samples. The application of multivariate analysis (PCA) demonstrated the connection between the elements of similar origin, in fine fractions mainly of anthropogenic origin, while in coarse mode of crustal origin, indicating the resuspension with contribution of about 40%. The contents of some measured elements were compared with their contents in aerosols in some European suburban areas.
本工作首次展示了在巴尔干半岛大陆的郊区对气溶胶的光谱分析中的元素分布。样品是在 2012 年 3 月至 2013 年 12 月期间在塞尔维亚贝尔格莱德郊区收集的。这里呈现的结果是对大小分类气溶胶和 PM 范围内的宏观和微量元素的长期测量结果。分析了以下元素：Al、Ag、As、Ba、Ca、Cd、Co、Cr、Cu、Fe、K、Mg、Mn、Mo、Na、Ni、Pb、Sb、Ti、Tl、V 和 Zn；在所有样品中，Be、Hg 和 Se 的水平均低于检测限。给出了颗粒物 (PM) 的平均浓度以及时间和季节性变化，以及元素含量及其百分比份额。结果表明，在 0.53 < Dp < 1.06 μm 的范围内，粒子含量主要集中在积聚模态，但元素的分数分布显示出取决于每个元素来源的不同分数中的最大平均浓度。地壳元素（Al、Ca、Fe、Mg、Mn、Ti 等）在粗模态中占主导地位，而人为元素（As、Cd、Cu、Pb、Sb 等）主要分布在细模态分数中。一些元素，如 As 和 Ni，仅偶尔在研究气溶胶中检测到，而其他元素，如 Ca、Fe 和 Mg，则在所有分析的样品中均检测到。多元分析（PCA）的应用表明了相似来源元素之间的联系，主要在细分数中为人为来源，而在粗模式中为地壳来源，表明约 40% 的再悬浮贡献。一些测量元素的含量与它们在一些欧洲郊区气溶胶中的含量进行了比较。
