A systematic study was carried out to investigate air deposition and to explore the natural distribution and enrichment (contamination) with trace elements in the small area (cca. 13 km(2)) of an antimony-arsenic-thallium mineralization outcrop at an abandoned mine "Allchar." The mine is located on the northwestern part of Kožuf Mount, Republic of Macedonia. The locality of Allchar is unique in its mineral composition; besides a very intriguing mineral, lorandite, there are 45 other minerals, some of which are rare. The distribution of 53 elements (with special attention to As, Sb, and Tl) were detected in 69 moss samples from eight various species collected from this area. Moss samples were analyzed following microwave digestion by inductively coupled plasma-mass spectrometry and inductively coupled plasma-atomic emission spectrometry. It was found that the atmospheric deposition for As in the moss samples on or around the Allchar mine is >6.5 times higher and for Tl is 19 times higher compared to values for the samples from the rest of the Allchar area. By the application of multivariate cluster and R-mode factor analyses (FA), five geochemical associations were determined. Cluster and R-mode FA were used to identify and characterize element associations, and five associations of elements were determined by the method of multivariate statistics. F1 (Co, Cr, Fe, Sc, Li, V, Ga, Y, Ni, Mn, Al, La-Lu, Cu, Ge, Be, Bi, and Hf); F2 (As, Tl, Sb, and Mg); F3 (Rb, Cs, and Mo); F4 (Sr, Ba, Hf, Zr, La-Lu, and Bi), and F5 (Cd, Zn, Ag, and Cu).
进行了一项系统研究，以调查空气沉积，并探索废弃的“Allchar”矿中锑砷铊矿露头小区域（约 13 平方公里）内微量元素的自然分布和富集（污染）情况。该矿位于马其顿科祖夫山的西北部。Allchar 矿区的矿物成分非常独特；除了一种非常有趣的矿物 lorandite 外，还有 45 种其他矿物，其中一些是稀有矿物。在该地区采集的 8 种不同物种的 69 个苔藓样本中，检测到了 53 种元素（特别关注 As、Sb 和 Tl）的分布情况。对来自 Allchar 矿区及其周边地区的苔藓样本进行了微波消解电感耦合等离子体质谱和电感耦合等离子体原子发射光谱分析。结果发现，与 Allchar 矿区其他地区的样本相比，苔藓样本中 As 的大气沉积量高出>6.5 倍，Tl 的沉积量高出 19 倍。通过多元聚类和 R 型因子分析（FA）的应用，确定了五个地球化学关联。聚类和 R 型 FA 用于识别和描述元素关联，通过多元统计方法确定了五个元素关联。F1（Co、Cr、Fe、Sc、Li、V、Ga、Y、Ni、Mn、Al、La-Lu、Cu、Ge、Be、Bi 和 Hf）；F2（As、Tl、Sb 和 Mg）；F3（Rb、Cs 和 Mo）；F4（Sr、Ba、Hf、Zr、La-Lu 和 Bi）和 F5（Cd、Zn、Ag 和 Cu）。
