煤矸石充填复垦区土壤重金属污染研究综述
|
摘要
以淮南矿区为研究对象,研究煤矸石充填复垦区重金属污染情况。煤矸石充填复垦区中的重金属含量超出正常土壤,且出现富集现象。土壤中重金属富集形态是重金属毒理效应及区域周围生态风险评价的重要指标,煤矸石复垦区中重金属多为残渣态与结合态。重金属污染评价多采用单因子指数法、地积累指数法、富集因子法和潜在危害生态法。复垦区土壤修复技术正朝着绿色与环境友好的方式转变,生物修复技术是最佳选择。
Taking Huainan mining area as the research object,the heavy metal pollution in coal gangue filling and reclaiming areas was studied. The content of heavy metals in the gangue-filled reclamation area exceeded that of normal soil and enrichment occurs. The enrichment of heavy metals in the soil was an important indicator of the toxicological effects of heavy metals and ecological risk assessment around the region. The heavy metals in coal gangue reclaimed areas were mostly in residue and bound state. The single factor index method,geoaccumulation index method,enrichment factor method and potential harm ecological method were commonly used in the evaluation of heavy metal pollution. Soil remediation technology in the reclamation area was moving in a green and environmentally friendly way, and bioremediation technology was the best choice.
