摘要(Abstract):
为探究西昌普诗碎屑岩地区紫色土中8种重(类)金属元素(Cu、Cd、Ni、Pb、Zn、Hg、As、Cr)的迁移富集特征及潜在生态风险,选取白垩系小坝组4个典型岩石-土壤剖面进行了系统的采样、测试和分析。结果表明,研究区土壤呈酸性—弱酸性,重金属元素Cd、Pb、Zn在剖面表层富集,与外源重金属元素叠加有关。此外,重金属元素的迁移富集特征还受到剖面风化程度、淋溶淀积作用、黏土矿物吸附作用及大气降尘等多种因素共同影响。单因子指数评价和内梅罗综合指数评价表明,研究区4个剖面均不存在土壤重金属元素污染问题。潜在生态风险评价表明研究区土壤整体处于低潜在生态污染水平,Hg和Cd元素存在中度潜在生态风险等级。建议相关部门加强土壤重金属元素的检测和监控力度,科学降低土壤重金属潜在生态风险。
