The proposed research is devoted to the effects of the urbanization on the soil cover through the assessment of common organic and inorganic pollutants as well as anthropogenic microartifacts (MAs) over 20 sites characterizing different land use areas within the city of Tyumen, Russia. The analytical methods included measurements of physical–chemical properties of soils (total organic carbon content, pH, and texture), the total concentrations of potentially toxic elements (V, Cr, Co, Ni, Cu, Zn, As, Sr, and Pb) using X-ray fluorescence analysis, and the concentrations of 12 priority polycyclic aromatic hydrocarbons using high-performance liquid chromatography, and the evaluation of the composition of anthropogenic MAs assemblies by optical microscopy. The results of the study showed that the soils of all studied sites within the industrial areas were characterized by a high level of combined pollution with elements and compounds. For other sites, the duration of urbanization was the strongest factor that influenced the levels of pollution. The sites with the highest pollution levels were also characterized by the highest proportion and diversity of MAs. In contrast to the urban soils of the cities in North America and Western Europe, anthropogenic MAs associated with the use of coal (ash, slag, and silicon spheres) were present, but to a far lesser extent. Apparently, this is due to the fairly late development and intensive growth of Tyumen in the second half of the twentieth century, as well as the use of natural gas and fuel oil. At the same time, MAs associated with construction and domestic debris prevailed both in the soils of demolition sites and residential areas, which indirectly indicates the rapid and chaotic nature of urbanization, characteristic of Tyumen.

利用微人工制品和地球化学指数评估历史发展对城市土壤的影响



拟议的研究致力于通过评估俄罗斯秋明市内 20 多个表征不同土地利用区域的地点的常见有机和无机污染物以及人为微人工制品 (MA),研究城市化对土壤覆盖的影响。分析方法包括测量土壤的物理化学性质(总有机碳含量、pH 值和质地)、潜在有毒元素(V、Cr、Co、Ni、Cu、Zn、As、Sr 和 Pb)的总浓度。 )使用 X 射线荧光分析,使用高效液相色谱法测定 12 种优先多环芳烃的浓度,并通过光学显微镜评估人为 MA 组件的组成。研究结果表明,工业区内所有研究地点的土壤都具有高水平的元素和化合物复合污染的特点。对于其他地点,城市化持续时间是影响污染水平的最强因素。污染水平最高的地点也具有最高的 MA 比例和多样性。与北美和西欧城市的城市土壤相比,存在与煤炭(灰、矿渣和硅球)的使用相关的人为MA,但程度要小得多。显然,这是由于秋明在二十世纪下半叶开发较晚、集约增长以及天然气和燃油的使用所致。与此同时,与建筑和生活垃圾相关的MA在拆除现场和居民区的土壤中普遍存在,这间接表明了秋明城市化的快速和混乱的特征。
