2016年，斯洛文尼亚老工业城镇马里博尔进行了首次系统的城市土壤地球化学调查。土壤性质（pH值，电导率，总碳，有机质）和56个王水可溶性元素测定118个采样点。通过检查其最高水平的空间分布和应用斯皮尔曼等级相关系数，发现自然分布元素和非自然分布元素之间存在相对明显的区别。土壤中铜、铅和锌的中位数水平显着高于相应的斯洛文尼亚中位数水平。它们的富集通常在工业区和老城区中心发现，这表明高水平是历史性的。此外，目前的工业活动以及公路和铁路交通也造成了这一水平的上升。此外，确定了几个孤立的地点，其中几种元素显著富集。没有发现广泛的扩散污染。许多元素的空间分布模式（例如，钴、铬、铁、钒）受该地区地质环境的影响，因为其最高土壤含量集中在火山变质的Pohorje山脚下。
The first systematic geochemical survey of urban soil in the old industrial town of Maribor, Slovenia, was performed in 2016. Soil properties (pH, electrical conductivity, total carbon, organic matter) and 56 aqua-regia soluble elements were determined from 118 sampling sites. A relatively clear distinction between naturally and anthropogenically distributed elements was found by inspection of the spatial distribution of their highest levels and by applying Spearman rank correlation coefficients. The median levels of Cu, Pb and Zn in the soil are significantly higher than the corresponding Slovenian median levels. Their enrichment is typically found in industrialised zones and the old town centre, suggesting that the elevated levels are historical. In addition, current industrial activities, as well as road and rail traffic contribute to increased levels. Additionally, a few isolated locations with significant enrichment of several elements were identified. Widespread diffuse contamination was not identified. Spatial distribution patterns of many elements (e.g., Co, Cr, Fe, V) are influenced by the geological setting of the area, as their highest soil levels are concentrated at the foot of the igneous-metamorphic Pohorje Mountains.
