摘要

采用原子吸收光谱(AAS)和电感耦合等离子体发射光谱(ICP - AES)法测定了密歇根州东南部某户外射击场表层和地下土壤中总Pb的分布。场地土壤中Pb的显著富集与射击弹丸产生的Pb蒸气和Pb颗粒物质以及休闲射击双向飞碟和捕集器产生的Pb/Sb弹丸的沉降密切相关。这些地点的表面浓度比邻近地点的背景浓度高10至100倍。地下土壤层位Pb的分布与地表Pb的分布相对应，表明Pb是通过渗透带向下运移的。尽管土壤富含粘土，但这种动员似乎仍在发生，可能是由于金属Pb转化为可溶的碳酸盐岩和硫酸盐Pb化合物:这两种化合物似乎存在于覆盖在许多土壤表面的地壳物质中。

Distribution and mobility of lead in soils at an outdoor shooting range

The distribution of total Pb in surface and subsurface soil horizons at an outdoor shooting range in southeastern Michigan was determined by single extraction elemental analysis (AAS and ICP‐AES). Significant Pb enrichment of the site's soils coincides closely with Pb vapor and particulate matter produced from shot shell primers and the downfall of Pb/Sb pellets associated with the recreational shooting of skeet and trap. Surface concentrations in these locations are 10 to 100 times greater than the background concentration found on adjacent properties. The distribution of Pb in the subsurface soil horizons corresponds to the distribution of Pb at the surface, which suggests the Pb is mobilizing and migrating downward through the vadose zone. This mobilization appears to be occurring despite the clay‐rich nature of the soils, and may be due to the transformation of metallic Pb into soluble Pb compounds of carbonate and sulfate: Both compounds appear to be present in crust material found coating many of th...
