  • 摘要: 利用地统计学方法对重庆某垃圾焚烧厂周边土壤的重金属（Cr、Mn、Cu、Pb、Zn、Fe）空间分布和污染特征进行研究，并利用Pearson系数法、主成分分析法、富集因子法进行重金属来源解析.结果表明，该垃圾焚烧厂周围土壤中上述6种重金属平均含量分别为216.74、639.33、33.67、47.96、69.79、38134.93 mg·kg-1，其中Fe、Mn平均含量与土壤背景值相当，其余重金属平均含量均高于背景值20%以上；源解析结果显示Fe、Mn主要是自然源，其余重金属主要来自人为源，其中占主导地位的是工业源和交通源；垃圾焚烧尾气排放尚未明显引起明显的土壤重金属污染.
    Abstract: This study characterized the spatial variability and pollution changes of heavy metal in soils around a municipal waste incinerator in Chongqing using geostatistical approach. 110 soil samples were collected from the top and deep layer of the soil near the plant to investigate heavy metal contamination. The results showed that the concentrations of Cr, Mn, Cu, Pb, Zn were 216.74, 639.33, 33.67, 47.96, 69.79 and 38134.93 mg·kg-1, respectively. The average concentrations of heavy metal in soil samples exceeded the natural background levels in Chongqing by approximately 20%, except for Fe and Mn. The source apportionment analysis demonstrates that Fe and Mn are manly affected by geological variations. Additionally, the content and distribution of Cr, Cu, Pb and Zn are influenced by anthropogenic activities, which are mainly industrialization and transportation practices. The results indicate that particulate emission from municipal waste incineration has no impact on heavy metal pollution in soil yet.
