当头发在硝酸、硫酸和高锰酸钾的混合物中消化时，可以得到快速消化和定量的汞回收。这些研究是在重复的样本上完成的，这些样本是从一个大的均匀的头发样本中提取的，作为标准参考。该方法应用于80名男性和147名女性（长期居住在加利福尼亚州洛斯阿拉莫斯市）和99名女性（长期居住在加利福尼亚州帕萨迪纳市）的头发样本。头发样本中汞浓度的几何平均值为：洛斯阿拉莫斯，18.0 μg/gm（男性）和18.9 μg/gm（女性）；帕萨迪纳，25.0 μg/gm。数值范围从5 μg/gm到100 μg/gm以上。发现的平均值比以前报道的要高。结果表明，这两个人群在汞环境暴露方面可能存在差异。
Rapid digestion and quantitative mercury recovery are obtained when hair is digested in a mixture of nitric acid, sulfuric acid, and potassium permanganate. The studies were done on replicate samples drawn from a large homogeneous hair sample used as a standard reference. The method was applied to hair samples from 80 men and 147 women, long-term residents of Los Alamos, NM, and 99 women, long-term residents of Pasadena, Calif. The geometric mean of the mercury concentration found in the hair samples was: Los Alamos, 18.0 μg/gm (men) and 18.9 μg/gm (women); Pasadena, 25.0 μg/gm. Values ranged from 5 μg/gm to over 100 μg/gm. The mean values found are higher than previously reported. The results suggest that there may be differences in the environmental exposure of the two populations to mercury.
