    摘要
  • 摘要: 硫铁矿及其伴生矿（金矿和铅锌矿）的开采会产生富含硫酸盐和重金属离子的酸性矿山废水，此类废水经地表径流进入周边水体和农田，所含重金属将持续污染水土环境。系统归纳了2013—2023年间报道的我国硫铁矿、金矿及铅锌矿区土壤中8种典型重金属（As、Cd、Cr、Cu、Hg、Ni、Pb、Zn）的浓度数据，分析了其时空分布、生态风险与健康风险。结果表明：三类矿区土壤中所有重金属的平均浓度均超过了其相应的省级背景值。空间上，硫铁矿污染以华中地区为重，金矿与铅锌矿污染分别集中于北部和南部。地累积指数与潜在生态风险评价表明，Cd、As、Pb和Hg是生态风险最高的元素。健康风险评估显示，经口摄入是主要暴露途径，儿童面临更高风险。考虑健康风险，应更多关注硫铁矿及其典型伴生矿（金矿和铅锌矿）区域As暴露的影响。
    Abstract: The mining of pyrite and its associated ores （gold and lead-zinc deposits） continuously generates acid mine drainage （AMD） rich in sulfate and heavy metal ions， posing risks to surrounding soil-water environments and human health. This study systematically collected data on the concentrations of eight heavy metals （As， Cd， Cr， Cu， Hg， Ni， Pb， and Zn） in soils from pyrite， gold， and lead-zinc mining areas in China from 2013 to 2023， and analyzed their spatiotemporal distribution， ecological risks， and health risks. The results showed that the average concentrations of all heavy metals in these mining areas exceeded their corresponding provincial background values. Spatially， pyrite-related contamination was most severe in Central China， while gold and lead-zinc mining contamination was mainly concentrated in the northern and southern regions， respectively. According to the geo-accumulation index and potential ecological risk assessment， Cd， As， Pb， and Hg were identified as the elements with the highest ecological risks. The health risk assessment indicated that hand-to-mouth ingestion was the primary exposure pathway， with children being more vulnerable. Considering the health risks， more attention should be given to the exposure of As in regions dominated by pyrite and its typical associated mineral areas （gold and lead-zinc deposits）.
