Abstract:Purpose：The pollution caused by heavy metals including As、Cd、Hg and Pb in the agricultural soils around the Yangshan gold deposit has been investigated, and the Anba ore section was taken as an example in this paper. Method：We have collected 80 topsoil and 15 vertical soil samples, combined using multiple methods to make the pollution assessment. Based on correlation analyses and previous geochemical results, the heavy metals sources and their vertical variations have been determined. Result：The average of As, Cd, Hg, and Pb concentrations is larger than that in the Longnan city. The As distributions are mainly influenced by human activities and belong to low-degree pollution. The As shows moderate accumulation. The Hg and Pb also display a certain degree of enrichment. The potential ecological hazard grade in the study area is medium. Conclusion：The shallow surface contains highly heavy metals, and their pollution may have diffused to the deeper depth. The As, Hg, and Pb were mainly derived from illegal gold mining and Pingdong construction, which were also influenced by transportation, whereas the Cd was mainly came from the soil materials. Meaning：That can provide the basis for later mine construction and development.
