摘要:
秦岭山区金属矿产资源丰富,但长期高强度、大规模的矿山开采遗留下来的矿山生态环境损害问题已经严重影响了秦巴地区的区域生态系统。为掌握秦岭山区金属矿山土壤中重金属污染物分布特征、生态风险以及迁移路径,本文以秦岭山区某金矿为研究对象,共采集69件样品(其中土壤样品50件、地表水样品19件),对Cd、Hg、As、Pb、Cr、Cu、Ni、Zn等8种重金属含量与pH进行分析。采用电感耦合等离子体质谱/发射光谱法(ICP-MS/OES)、原子荧光光谱法(AFS)等方法测定元素含量,研究矿区土壤中重金属污染程度与空间分布特征,并对矿区重金属的迁移路径进行了解析,采用单因子指数法、内梅罗综合指数法和潜在生态风险指数法对研究区土壤重金属污染程度和潜在生态风险进行评价。结果表明:①研究区内As、Cd、Hg、Cu、Ni变异系数较大,人为影响因素显著,As与Cd的污染最为严重,每个区域的检出结果均超出背景值。②从空间含量分布来看,尾矿库受重金属污染最为严重,其中As、Cd、Cr、Cu、Pb最高分别可超背景值28.9、22.6、1.41、8.69、0.345倍,农用地与工业场地次之,这与单项指数法、内梅罗综合污染指数法和潜在生态风险指数法的分析结果基本一致。③通过污染路径解析可知,采矿工程是引起研究区周边生态环境损害的重要原因,其中尾矿库渗水、硐口涌水是尤为显著的地表水污染源,而被污染的地表水又是引起农用地土壤污染的重要原因。
Abstract:BACKGROUNDThe Qinling Mountains are rich in metal mineral resources, but the problem of mine ecological environment damage left over from long-term high-intensity and large-scale mining has seriously affected the regional ecosystem in the Qinba area. Therefore, it is essential to objectively assess the characteristics and ecological risks of heavy metal pollution in the soil of the mining area, and to find out the migration path of heavy metals. In recent years, domestic and foreign scholars have carried out a lot of research work from the aspects of pollutant distribution characteristics[7-8], risk assessment[9-12], source analysis[13], etc. The distribution characteristics, risk assessment and migration path analysis of heavy metal pollutants in metal mine soil in the Qinling Mountain area need to be supplemented.
OBJECTIVESTo understand the pollution characteristics, migration path and pollution degree of soil heavy metal in metal mines of the Qinling Mountains.
METHODSA total of 50 soil samples and 19 surface water samples were collected in the study area. AFS, ICP-MS/OES were used to determine the contents of 8 heavy metals (Cd, Hg, As, Pb, Cr, Cu, Ni, Zn). The pollution degree and spatial distribution characteristics of heavy metals in the soil of the mining area were studied, and the migration path of heavy metals in the mining area was analyzed. The level of contamination and ecological risks was analyzed using the individual pollution index, Nemerow comprehensive pollution index and the potential ecological risk index.
RESULTSThe variation coefficient of As, Cd, Hg, Cu and Ni in the study area was large, and indicated that human intervention was more significant than initially thought. The pollution of As and Cd was the most serious; all the detection results exceeded the background value. The single Nemerow pollution index of Cd, Hg, As and Cu in the soil of the tailings pond area were all severe pollution grade, which were 18.60, 3.91, 24.62 and 6.96 times, respectively. The pollution level of Cd and As in agricultural land reached the severe pollution level, 5.36 and 4.99 times respectively. No detection index of industrial site reached the severe pollution level.
From the perspective of spatial content distribution, the tailings pond was the most seriously polluted by heavy metals, among which As, Cd, Cr, Cu and Pb exceeded the background value by 28.9, 22.6, 1.41, 8.69 and 0.345 times, respectively. Agricultural land and the industrial site followed, which was consistent with the analysis results of the single index method, Nemerow comprehensive pollution index method and potential ecological risk index method. Weighting the data by Nemerow composite pollution index of the 8 heavy metals, the tailings pond was 19.11, reaching the level of severe pollution; agricultural land was 2.86, which was moderately polluted; the industrial site was 0.96, which was the warning value. The analysis results of potential ecological risk assessment index of heavy metals showed that the comprehensive risk index of tailings pond was 255.9, presenting a medium risk grade. Agricultural land was 130.23, which was low ecological risk grade. The industrial site was 152.66, which was medium risk.
CONCLUSIONSAccording to the analysis of pollution path, it can be seen that mining engineering is an important cause of ecological environmental damage around the study area, among which water seepage and water gushing at the tailings pond are particularly significant pollution sources, and polluted surface water is an important cause of soil pollution on agricultural land. It is suggested that heavy metal pollution in the tailings pond should be the focus for later restoration and treatment process of soil ecological environment in mining areas, and heavy metal indicators such as As, Cd, Hg and Cr should be continuously monitored.
