A field survey was performed to investigate the metals contamination in the vicinity of tungsten mining areas. Ten sampling sites alongside perennial wind direction were selected for soil collection and heavy metal contents determination, include Cr, Cu, Zn, Pb, As, Cd, and W. Horizontal and vertical distribution characteristics of metals were performed. Geo-accumulation and potential ecological risk of soil samples were discussed for a description of risk assessment. The results showed that the mean concentrations of all metals in soil samples exceeded the background value of Jiangxi background. The heavy metal contents in vertical profiles revealed the surface accumulation of Cd, W, and Pb, while, As increased as soil depth increased. The geo-accumulation index shown the highest pollution level of W and followed by Cd. Single ecological risk factor ($E_r^i$) figured out that the contamination degree followed the sequence of Cd>As>W>Zn>Pb>Cr>Cu. Furthermore, the potential ecological risk index ($RI$) was calculated for risk level assessment, and Cd takes account the most contribution in surface soil, followed by W and As.

进行了现场调查，以调查钨矿开采区附近的金属污染。沿常年风向选择了10个采样点用于土壤收集和重金属含量测定，包括Cr，Cu，Zn，Pb，As，Cd和W。进行了金属的水平和垂直分布特征。讨论了土壤样本的地质累积和潜在生态风险，以描述风险评估。结果表明，土壤样品中所有金属的平均浓度均超过江西本底值。垂直剖面中的重金属含量显示了Cd，W和Pb的表面积累，而随着土壤深度的增加，As的增加。地质累积指数显示出最高的W污染水平，其次是Cd。${Ë}_{\mathrm{[R}}^{\mathrm{一世}}$）发现污染程度遵循Cd> As> W> Zn> Pb> Cr> Cu的顺序。此外，潜在的生态风险指数（$\mathrm{[R}\mathrm{一世}$）被计算用于风险水平评估，Cd考虑了表层土壤的最大贡献，其次是W和As。
