| 摘 要： | 对鄂东南矿集区的山间盆地、长江冲积平原和低山丘陵地形土壤As的系统测定表明;土壤母质是影响土壤As区域背景值的主要因素,在相同的地理和气候条件下,土壤的pH、Eh值是控制土壤As垂向分布的重要条件之一;矿集区内土壤As污染主要有自然污染和人为污染,两类污染土壤在As含量垂向分布及土壤pH等理化性质上有着明显的区别.

| Abstract: | 77 soil samples and 34 soil sections from intermontane basins and alluvial plains along the Yangtze River and hilly lands in southeast Hubei were analyzed. A systematic analysis of pH and Eh values and arsenic concentration indicates that soil material is the chief factor affecting the content of As. Under the same geographical and climatic conditions, the pH and Eh values of soil seem to be the most important factors governing the vertical distribution of As. In the ore cluster areas, the soil is contaminated by As both naturally and artificially. There are many conspicuous physical and chemical differences between the two kinds of polluted soils in the vertical distribution of As content and in the pH values of soil. |
