Soil samples were collected on farmland in a lead-zinc mining area in the Karst region of Guangxi, China. The contamination of the soil by eight metals (Cd, Hg, As, Cu, Pb, Cr, Zn, Ni) was determined. Among all these metals, Cd is the most serious pollutant in this area. Zn, Hg as well asPb can also be measured at high levels, which may affect the crop production. All other metals contributed marginally to the overall soil contamination. Besides the evaluation of single metals, the Nemerow synthetic index indicated that the soil is not suitable for agricultural use.
在中国广西喀斯特地区的一个铅锌矿区农田上采集了土壤样本。测定了土壤中八种金属（Cd、Hg、As、Cu、Pb、Cr、Zn、Ni）的污染情况。在所有这些金属中，Cd 是该地区最严重的污染物。Zn、Hg 以及 Pb 的含量也很高，这可能会影响作物的产量。其他所有金属对整体土壤污染的贡献都较小。除了对单一金属的评估外，内梅罗综合指数还表明，该土壤不适合农业使用。
