【摘要】：目的了解川藏沿线各兵站生活饮用水源水中重金属含量及当地官兵头发中汞含量,为制定保障官兵身体健康措施提供依据。方法采用原子荧光光度法对川藏沿线18个兵站水源水中汞、砷、铅、硒4种重金属及部分官兵头发中汞含量进行测定,用单侧Fisher确切概率法对水汞和发汞进行相关性统计分析。结果川藏沿线18个兵站中,有2个兵站水源水汞超标,质量浓度分别达1.027μg.L-1和1.350μg.L-1;有1个兵站水源水铅超标,质量浓度为25.101μg.L-1。川藏沿线兵站官兵发汞平均质量浓度为1.071μg.g-1,超过我国正常人群1.0μg.g-1的平均发汞水平,最高质量浓度达3.245μg.g-1。结论川藏沿线兵站官兵存在发汞含量超标的现象,通过水汞和发汞的相关性统计,暂未发现饮用水源中汞含量与人群发汞之间存在必然联系。
[Abstract]:Objective to understand the contents of heavy metals in drinking water and the mercury content in the hair of local officers and soldiers in the military stations along Sichuan and Tibet in order to provide the basis for making measures to protect the health of officers and soldiers. Methods Mercury, arsenic, lead and selenium in water of 18 military stations along Sichuan and Tibet were determined by atomic fluorescence spectrophotometry, and mercury content in hair of some officers and soldiers were determined. The correlation between mercury in water and mercury in hair was analyzed by single side Fisher exact probability method. Results among the 18 military stations along Sichuan and Tibet, 2 of them exceeded the standard of water mercury, the mass concentration of mercury was 1.027 渭 g.L-1 and 1.350 渭 g 路L ~ (-1), respectively, and one of them exceeded the standard of water lead with a mass concentration of 25.101 渭 g 路L ~ (-1). The average mass concentration of mercury was 1.071 渭 g 路g ~ (-1), which was higher than that of normal population (1.0 渭 g.g-1), and the highest mass concentration was 3.245 渭 g 路g ~ (-1). Conclusion there is a phenomenon that the mercury content in the hair of officers and soldiers in the military station along Sichuan and Tibet exceeds the standard. Through the statistics of the correlation between mercury in water and mercury in hair, it is not found that there is an inevitable relationship between mercury content in drinking water source and human hair mercury.
