矿区周边农田重金属污染阻控与修复措施研究进展
Research Progress on Control and Remediation Measures for Heavy Metal Pollution in Farmland Around Mining Areas
摘要
Abstract
Based on relevant research literature and practical work at home and abroad,this study analyzed the current situation of heavy met-al pollution in the farmland around mining areas caused by mining and smelting activities,and explored the sources,characteristics,and risks,as well as the environmental effects such as migration and transformation of heavy metals in the farmland and the control and remediation measures.The results show that the heavy metal pollution in the farmland around mining areas in China is serious,with many over-standard points and severe ecological risks.The pollution mainly comes from tailings weathering,mining wastewater,and atmospheric deposition.Heavy metal composite and superimposed pollution is widespread in the farmland,and the degree of pollution is related to the distance from the pollu-tion source.It poses a high risk to the soil environment,crop safety,and human health.The migration and transformation of heavy metals in farmland are easily affected by multiple factors such as precipitation,irrigation,soil physical and chemical properties,and soil organisms.Physical,chemical,and biological control or remediation methods can be used to treat the heavy metal pollution in the farmland around mining areas.The heavy metal pollution in the farmland around mining areas is highly concealed and latent.Traditional treatment methods and risk as-sessment monitoring methods need to be innovated.By combining geochemical and remote sensing technologies,the heavy metal pollution in the soil of mining areas can be accurately inverted,and the spatial distribution characteristics of heavy metal content in the soil of mining areas can be clearly understood.Strengthening the research on key technologies for pollution control at the field scale,while quickly cutting off pollu-tion sources based on local conditions,and comprehensively applying physical,chemical,and biological technologies,can help to effectively curb the spread of heavy metal pollution and promote in-depth governance.关键词
