摘　　要：就海湾泥、粉煤灰、碱渣3种固体废弃物作为替代种植基质利用中是否存在重金属及有机污染物污染问题进行了探讨,试验结果表明碱渣中重金属含量均符合国家土壤环境质量一级标准,粉煤灰、海湾泥中砷含量较高,海湾泥中砷含量与沉积地点有关,将三者按适当比例混合掺拌形成新土源的重金属含量符合土壤环境质量一、二级标准,而基质上种植植物重金属含量及其分布因植物而异,但不会对植物生长带来危害,对环境也不会造成二次污染,可以大面积推广应用。Whether three solid wastes, sea sediment, coal ash, caustic-sludge, contain heavy metal or organic contamination is discussed in this paper. The results show that the content of heavy metal in caustic-sludge meets the first-degree environmental quality standard for soil, and the contents of arsenic for sea sediment and coal ash are high, and are relevant to deposited sites of sea sediment. However, the content of heavy metal of artificial soil meet the first or second-degree standard, which consist of the three solid wastes above-mentioned at appropriate mixture ratio. The content and distribution of As, I/g, Pb, CA are various along with plant species in plants.
