土壤重金属形态与溶解性有机物的环境行为

土壤中重金属的污染已成为日趋严重的环境问题,重金属在土壤中的富集过程和迁移转化规律与土壤中重金属赋存形态有着密切的联系。文章阐述了土壤中重金属的赋存形态及其影响因素,并介绍了溶解性有机物质(DOM)与土壤中重金属间的环境化学行为,为更加科学合理利用和修复受重金属污染土壤以及为土壤环境污染风险评估与预测提供准确、可靠的理论支持。

Heavy Metal Species in Soil and Environment Behavior of Dissolved Organic Matter

Heavy metals pollution in soil is becoming an increasingly serious environment problem. Enrichment process as well as migration and transformation of heavy metals in soil are closely linked with heavy metals speciation. Heavy metal species in soil and its impact factors were described, and environment chemical behavior between dissolved organic matter (DOM) and heavy metals in soil were introduced, which will offer a reliable theoretical support for a more scientific and rational use and repair of heavy metal contamination of soil as well as risk assessment and prediction of soil environment pollution.
