Abstract This study extends the program of urban soil geochemical mapping in Cyprus to Lemesos, the country’s second largest and fastest developing urban centre. Data from 411 soil samples are combined with samples previously analysed as part of the detailed soil geochemical atlas of Cyprus (GAC). Parent lithology is the dominant control on the distribution of most elements with soils derived from carbonate units contrasting with those developed on alluvium-colluvium that contains input from both the carbonates and mafic-ultramafic units of the nearby Troodos Ophiolite. Anthropogenic contamination is best indicated by the Pb-Sn-Ag-Bi suite with elevated values in a belt crossing the southern and older section of the city that is unrelated to parent lithology or current land use classification. As in Lefkosia, children’s playgrounds display much higher As contents than at other sites due to application of a natural secondary carbonate (‘pouri’) as the surface layer, and elevated concentrations of Cu, Fe, Ti, Al, S and Mn associated with basaltic soils used in most school grounds. Multivariate patterns in the Lemesos data largely reflect those of similar parent lithologies within the national soil atlas, but there is closer clustering of the contamination-related elements and an ultramafic suite involving Ni-Cr-Pt-Pd-V-Co in Lemesos. Whereas most elements display multifractal populations using number-size fractal modelling, in urban and contaminated areas some higher concentration element populations do not display fractal behaviour, thus providing a means of identifying anthropogenic influences.

塞浦路斯 Lemesos (Limassol) 土壤地球化学分形特征的控制

摘要 本研究将塞浦路斯的城市土壤地球化学绘图计划扩展到该国第二大和发展最快的城市中心 Lemesos。来自 411 个土壤样品的数据与之前作为塞浦路斯详细土壤地球化学图集 (GAC) 的一部分进行分析的样品相结合。母岩性是大多数元素分布的主要控制因素，土壤源自碳酸盐单元，而在冲积层上发育的土壤则包含来自附近 Troodos 蛇绿岩的碳酸盐和镁铁质-超镁铁质单元的输入。人为污染最好由 Pb-Sn-Ag-Bi 套件指示，该套件在穿过城市南部和较旧部分的带中具有升高的值，与母岩性或当前的土地利用分类无关。和莱夫科西亚一样，由于使用天然次生碳酸盐 ('pouri') 作为表层，以及与玄武岩土壤相关的 Cu、Fe、Ti、Al、S 和 Mn 浓度升高，儿童游乐场的砷含量比其他场地高得多。大多数校园。Lemesos 数据中的多元模式在很大程度上反映了国家土壤图集中相似母岩性的模式，但在 Lemesos 中，与污染相关的元素和超镁铁质组的聚类更紧密，其中包括 Ni-Cr-Pt-Pd-V-Co。尽管大多数元素使用数字大小的分形模型显示多重分形种群，但在城市和污染地区，一些较高浓度的元素种群不显示分形行为，从而提供了一种识别人为影响的方法。
