中文摘要：[研究目的]本文采集了表层土壤样品 34件,分析测定Hg、Cd、As、Pb、Cu、Cr、Zn、Ni等 8种重金属元素含量;获取胶东半岛某金矿周边土壤重金属污染特征,分析土壤重金属来源并进行风险评价.[研究方法]运用相关性分析和主成分分析方法探索土壤重金属的来源,运用单项污染评价和地累积指数法确定其污染程度,采用潜在生态风险评价和人体健康风险评价的方法评估其风险.[研究结果](1)全区仅存在 3处点源污染,1处为Hg元素污染,2处为Cd元素污染;(2)元素Ni、Cr和As主要来自于土壤母质,元素Pb、Cd、Zn和Hg主要来自于矿业活动,Cu元素主要来自土壤母质和农业活动;(3)个别点状区域存在较高的潜在生态风险,风险主要来自于元素Hg和Cd,其他元素基本上不存在风险;(4)人体健康风险评价结果表明,全区土壤中的重金属元素未对人体产生明显的健康风险.[结论]该金矿周边的土壤受到了矿业活动的影响,并出现了点状污染,但程度较轻,风险可控,应当加强对该区域土壤重金属的监测和评价.

外文标题：Pollution characteristics,source analysis and risk assessment of heavy metals in soil around a gold mine in Jiaodong Peninsula

外文摘要：This paper is the result of environmental geological survey engineering.[Objective]This paper collected 34 surface soil samples to analyze and determine the concentrations of eight heavy metal,including Hg,Cd,As,Pb,Cu,Cr,Zn,and Ni.The objective was to characterize the heavy metal pollution in the soil around a gold mine,identify the sources of heavy metals in the soil,and conduct a risk assessment.[Methods]Correlation analysis and principal component analysis were used to explore the sources of heavy metals in the soil.Single pollution evaluation and geo-accumulation index method were employed to determine the degree of pollution.Potential ecological risk assessment and human health risk assessment methods were utilized to evaluate the risks.[Results](1)Only three point source pollutions were found in the study area:one for Hg contamination and two for Cd contamination.(2)Nickel,chromium,and arsenic mainly originated from soil parent materials,while lead,cadmium,zinc,and mercury primarily came from mining activities.Copper was derived from both soil parent materials and agricultural activities.(3)Some localized areas demonstrated high potential ecological risks,mainly due to Hg and Cd,while other elements posed minimal risks.(4)Human health risk assessment indicated that the heavy metal elements in the soil did not pose significant health risks to humans.[Conclusions]The soil around the gold mine was influenced by mining activities and exhibited localized pollution,albeit at a low level.The risks were manageable,but monitoring and assessment of heavy metals in this area should be strengthened.
