为探究含硅含硫材料对极重度(矿区)镉砷复合污染土壤镉、砷形态动态变化的影响,以及轻、重度镉砷复合污染耕地土壤与淹水条件下含硅含硫材料对土壤镉、砷形态变化的影响,本试验采集三种不同污染程度土壤(极重度矿区污染土壤、重度污染耕地土壤、轻度污染耕地土壤),通过室内土壤培养的方法模拟施用含硅含硫材料,研究单一施用(G、S)、混合施用(G S)和混合施用结合淹水处理(G SI)对轻、重度耕地土壤镉砷赋存形态的影响,单一施用(G 1、G2、S1、S2)、混合施用(G S1、GS2)以及不同施用浓度处理对极重度矿区污染土壤镉砷赋存形态的影响。结果表明:含硅、含硫材料均能降低矿区镉砷复合污染土壤中弱酸可溶...

Dynamic changes in cadmium and arsenic species in soils polluted by silicon- and sulfur-containing materials under extremely severe cadmium and arsenic contamination（such as in mines）were investigated. This experiment collected three kinds of soils with different pollution levels（extremely severely polluted soils, severely polluted soils, and mildly polluted soils）. The indoor soil cultivation method was used to simulate the application of silicon and sulfur-containing materials to research the effect of the single application（G, S）and mi...
