这篇文章的主要目的是评估大气污染与重金属由于铜矿布伊姆附近的拉多维，马其顿共和国。露天矿和矿山废物以及浮选尾矿不断暴露在露天，这导致风将细颗粒带入大气中。对阁楼灰尘样本进行了检查，作为矿山排放物的历史档案，目的是阐明污染的途径。灰尘是从1920年至1970年间建造的29所房屋的阁楼上收集的。采用电感耦合等离子体原子发射光谱法分析了19种元素（Ag、Al、As、Ba、Ca、Cd、Co、Cr、Cu、Li、Fe、K、Mg、Mn、Na、Ni、Pb、Sr和Zn）。采用非参数和参数分析对阁楼灰尘样品中所调查元素的测定值进行了统计处理。因子分析揭示了三个因素的个别化学元素的来源。其中两个组Ca，Li，Mg，Mn和Sr（因子1）和Co，Cr和Ni（因子2）可以被表征为地质成因。第三个因素分组砷，铜，铅是人为的，反映了粉尘沉降从采矿作业和浮选尾矿。绘制了这组元素的面沉积图，从中证实了这些人为元素的相关性。
The main aim of this article was to assess the atmospheric pollution with heavy metals due to copper mining Buim near Radovi, the Republic of Macedonia. The open pit and mine waste and flotation tailings are continually exposed to open air, which leads to winds carrying the fine particles into the atmosphere. Samples of attic dust were examined as historical archives of mine emissions, with the aim of elucidating the pathways of pollution. Dust was collected from the attics of 29 houses, built between 1920 and 1970. Nineteen elements (Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Li, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, and Zn) were analyzed by atomic emission spectrometry with inductively coupled plasma. The obtained values of the investigated elements in attic dust samples were statistically processed using nonparametric and parametric analysis. Factor analysis revealed three factors governing the source of individual chemical elements. Two of them grouping Ca, Li, Mg, Mn, and Sr (Factor 1) and Co, Cr, and Ni (Factor 2) can be characterized as geogenic. The third factor grouping As, Cu, and Pb is anthropogenic and mirrors dust fallout from mining operation and from flotation tailings. Maps of areal deposition were prepared for this group of elements, from which correlation of these anthropogenic born elements was confirmed.
