摘要
锰矿区土壤重金属含量高,对作物以及生态均有不利影响。为有效评估锰矿区土壤重金属污染情况,以某锰矿区为案例,检测土壤中的重金属物质含量。研究引入综合污染指数法等来评估矿区土壤重金属污染程度,同时引入潜在生态危害指数法来监测矿区生态情况。结果分析表明,污染区调查出锰、锌、镍、铜、铬、砷、铅、镉8种重金属,土壤中锌、铜、镉、砷、铅超标率超过93.25%。污染区中镉、锰是单因子污染影响最大的两种重金属,污染区综合评估结果为重度污染。而在生态监测中,镉、铅、砷对生态潜在风险影响最大。可见,该地区污染严重,需要采取必要的环境治理措施。
The high content of heavy metals in the soil of manganese mining areas has adverse effects on crops and ecology.To effectively evaluate the heavy metal pollution in the soil of a manganese mining area,a case study was conducted to detect the content of heavy metal substances in the soil of a certain manganese mining area.The study introduces comprehensive pollution index method to evaluate the degree of heavy metal pollution in soil in mining areas,and introduces potential ecological hazard index method to monitor the ecological situation in mining areas.The analysis of the results showed that eight heavy metals,including manganese,zinc,nickel,copper,chromium,arsenic,lead,and cadmium,were identified in the polluted area.The exceedance rate of zinc,copper,cadmium,arsenic,and lead in the soil exceeded 93.25%.Cadmium and manganese are the two heavy metals most affected by single factor pollution in the polluted area,and the comprehensive assessment of the polluted area shows severe pollution.In ecological monitoring,cadmium,lead,and arsenic have the greatest potential impact on ecological risks.It can be seen that the pollution in this area is severe and necessary environmental governance measures need to be taken.
