    小秦岭金矿带某污染区村民头发中重金属元素的含量

    Contents of heavy metals in villagers’ hair in contaminated areas of the Xiaoqinling gold belt

    • 摘要: 为了定量化揭示污染区人群头发中重金属元素的累积状况及其对人群健康的危害,在小秦岭金矿带某环境污染区走访调查村民的健康状况,采集分析了20位村民头发中的Hg、Pb、Cd、As、Cr、Cu的含量,与未污染的对照区村民头发重金属元素的含量作比对分析。结果显示,职业暴露或低水平长期接触导致污染区人群头发中重金属元素的含量显著增高,直接从事提金活动的人群头发中的重金属元素含量明显高于低水平暴露人群,头发中重金属元素的含量较好地指示了人群健康的状况。研究成果为政府加大矿山环境污染防治的力度提供了科学依据。

       

      Abstract: In contaminated areas of the Xiaoqinling gold mine, Hg and Pb contents in hair of local people are significantly higher than those in the control area. In order to reveal quantitatively the accumulation of heavy metals in people’s hair in the contaminated area and their harm to people’s health, the authors investigated the health conditions of villages in a certain contaminated area and collected Hg, Pb, Cd, As, Cr and Cu samples and analyzed their contents in hair of 20 villagers, which were compared with the heavy metal contents of villages in uncontaminated contrast areas. Occupational exposure or long-term exposure to heavy metals is the main cause for the significant increase of the heavy metal content in human hair in contaminated areas. The heavy metal content in hair of people who directly dealt with gold smelting is notably higher than that in hair of low-level exposed people. The content of heavy metals in hair may better indicate people’s health conditions. The research results provide a scientific basis for the government’s making more efforts to implement prevention and control of mine environment contamination.
