The potential of using land cover/use categories as a proxy for soil metal concentrations was examined by measuring associations between Anderson land cover category percentages and soil concentrations of As, Pb, and Ba in ten sampling areas. Land cover category and metal associations with ethnicity and socioeconomic status at the United States Census 2000 block and block group levels also were investigated. Arsenic and Pb were highest in urban locations; Ba was a function of geology. Consistent associations were observed between urban/built up land cover, and Pb and poverty. Land cover can be used as proxy for metal concentrations, although associations are metal-dependent.
通过测量十个采样区域中安德森土地覆盖类别百分比与土壤中砷、铅和钡浓度之间的关联，研究了使用土地覆盖/利用类别作为土壤金属浓度替代指标的潜力。还调查了美国2000年人口普查街区和街区组层面上土地覆盖类别及金属与种族和社会经济地位之间的关联。城市地区的砷和铅含量最高；钡含量取决于地质情况。在城市/建成区土地覆盖与铅及贫困之间观察到了一致的关联。尽管这些关联因金属而异，但土地覆盖可作为金属浓度的替代指标。
