摘要
当今社会工业越来越发达,对矿产资源的需求量在不断增加,但是随着对矿山的开采,矿区周边土壤出现重金属污染情况,危及人体及生态安全,为此提出矿区周边土壤重金属污染特征及潜在生态风险评估这一课题。通过构建评估模型,评估矿区周边土壤重金属污染特征,判断污染土壤的重金属元素以及污染范围状况;评估矿区周边土壤重金属污染潜在生态风险,积极控制重金属污染扩散,避免重金属污染对矿区周边土壤的进一步污染。
Nowadays,the social industry is more and more developed,and the demand for mineral resources is increasing.However,with the mining of the mine,heavy metal pollution occurs in the surrounding soil of the mining area,which endangers the human body and ecological safety.Therefore,the topic of heavy metal pollution characteristics and potential ecological risk assessment of the surrounding soil of the mining area is proposed.Through the construction of assessment model,the characteristics of heavy metal pollution in the surrounding soil of the mining area are assessed,and the heavy metal elements and pollution scope of the polluted soil are judged;the potential ecological risk of heavy metal pollution in the surrounding soil of the mining area is assessed,and the diffusion of heavy metal pollution is actively controlled to avoid the further pollution of heavy metal pollution to the surrounding soil of the mining area.
