| 中文摘要: |
| 对西安南郊葡萄种植区六个取样点的葡萄种植土壤进行采集，经混酸消解后，用原子吸收分光光度计测定Pb、Cd、Cr和Cu四种重金属含量，结果表明，六处采样点土壤中四种重金属含量均超过陕西省土壤中四种重金属背景值。对样品测定数据采用内梅罗（Nemerov）综合污染指数( P综) 分析，结果表明，六处采样点的土壤均处于四种重金属的重度污染等级。采用地累积指数（Igeo）分析结果表明，该六处采样点受到Cd、Cu污染非常明显，Cd污染尤其严重。 |
| 英文摘要: |
| Soil samples were collected from six grape cultivation sites in the southern suburbs of Xi’an. After mixed acid digestion, the concentrations of Pb, Cd, Cr, and Cu were measured using atomic absorption spectrophotometry. The results indicated that the concentrations of all four heavy metals in the samples exceeded the background values for soils in Shaanxi Province.The pollution levels were assessed using the Nemerov comprehensive pollution index. The analysis showed that all six sites were classified as severely polluted by all four heavy metals. An assessment using the geo accumulation index (I_geo) revealed that Cd and Cu contamination was particularly prominent. Cd, in particular, posed a severe pollution risk. |
