摘要
本文综述了土壤中As污染的主要污染源,土壤中主要含As化合物的形态及转化,土壤对As的吸附缓冲行为,土壤As对植物和微生物的生态毒理及微生物在As不同形态转化中的作用等方面的研究成果;并分析了尚需加强研究的方面。
Main authigenic sources of Arsenic pollution and forms and transformation of the major As containing compounds in the soil, are summarized. Research findings on adsorptive amortization of the soil to Arsenic, eco-toxicology of soil As to plants and micro-organisms and roles of micro-organisms in transformation of Arsenic in the soil are reviewed. And prospects of the research of Arsenic pollution in the soil are analyzed.
