必须确定土壤中金属和类金属的浓度和来源，才能在区域一级建立质量标准，并评估金属对食品安全和人类健康的潜在威胁。以每4 km2 1个样品的密度，在海南岛收集了8713个土壤样品，分析了As、Cd、Cr、Cu、Hg、Ni、Pb、Se和Zn的浓度。As、Cd、Cr、Cu、Hg、Ni、Pb、Se和Zn的几何平均值分别为2.17、0.60、26.5、9.43、0.033、8.74、22.2、0.26和39.6 mg··kg−1，除Se外显著低于中国土壤背景值。主成分分析表明，海南环境元素组成受多种人为源的调控。煤炭燃烧和开采是海南重要的人为金属来源。利用地理信息系统（GIS）方法绘制了海南土壤元素地球化学图，并确定了几个热点区域。As、Cd、Cu、Cr、Hg、Pb、Ni、Zn污染对土壤的生态影响极“低”。
The characterization of the concentrations and sources of metals and metalloids in soils is necessary to establish quality standards on a regional level and to assess the potential threat of metals to food safety and human health. A total of 8713 soil samples throughout Hainan Island, China were collected at a density of one sample per 4 km2, and concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn were analyzed. The geometric mean values of the elements were 2.17, 0.60, 26.5, 9.43, 0.033, 8.74, 22.2, 0.26, and 39.6 mg·· kg−1 for As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn, respectively, significantly lower than the background values of Chinese soils with the exception of Se. Principal component analysis (PCA) suggested that multiple anthropogenic sources regulated the elemental compositions of the Hainan environment. Coal combustion and mining are important anthropogenic sources of metals for Hainan. The geochemical maps of elements in Hainan soils were produced using the Geographic Information System (GIS) method, and several hot-spot areas were identified. The ecological impact of As, Cd, Cu, Cr, Hg, Pb, Ni, and Zn pollution to the soils was extremely “low”.
