We investigated the characteristics of metal(loid) transport and dispersion in agricultural soils near an abandoned metal mine. Topsoil samples were collected from 162 sampling sites in the study area, including 1 in the mine tailing dumps, to analyze the total concentrations of As, Pb, Cd, and Zn. Subsequently, the metal(loid) transport and dispersion characteristics were investigated using geographic information system (GIS) technology. The results of this study clearly demonstrated the variation in the dispersal of As, Cd, Pb, and Zn from the mine tailing dumps to nearby agricultural soils and the element-specific spatial variability in their respective transport and dispersion characteristics. These findings suggested that compared with the migration behavior of Cd, Pb, and Zn, that of As has a farther-reaching impact on agricultural soils owing to its geochemical cycling in the soil and groundwater environment. This impact differed significantly in magnitude from that of the other investigated metals. Therefore, special consideration must be given to the migration behavior of As.

废弃尾矿附近农田土壤中As、Cd、Pb和Zn的不同分布：韩国实地观察结果

我们研究了废弃金属矿附近农业土壤中金属（液体）运输和扩散的特征。从研究区的 162 个采样点采集表土样品，其中 1 个在矿山尾矿堆中，用于分析 As、Pb、Cd 和 Zn 的总浓度。随后，利用地理信息系统（GIS）技术研究了金属（液体）输运和弥散特性。本研究的结果清楚地证明了从尾矿堆场到附近农业土壤的 As、Cd、Pb 和 Zn 扩散的变化，以及它们各自运输和扩散特征的特定元素空间变异性。这些发现表明，与 Cd、Pb 和 Zn 的迁移行为相比，由于其在土壤和地下水环境中的地球化学循环，As 对农业土壤的影响更为深远。这种影响在幅度上与其他研究的金属的影响大不相同。因此，必须特别考虑 As 的迁移行为。
