Metal ions of exogenous origin can penetrate into the hair and can be accumulated. Penetration and distribution of metal ions could be examined by means of electron microprobe-analysis. The dependence of the accumulation of different kations on the concentration of these in the surrounding solutions have been determined by atomic absorption spectroscopy. The dimension of accumulation depends on various factors: the chemical nature of the ion involved, its concentration in the solution and the solutions pH-value, the nature of the anions present as well as the nature and concentration of other kations. The distribution of the kations in the hair can be changed by washing with distilled water. The significance of the present physical-chemical experiments with hairs for criminology, toxicology and to environmental protection were discussed in detail. It was shown that the content of zinc in the hair is of predominantly endogenous origin; moreover, a strong accumulation in the hair root took place. The study of the accumulation mechanism should contribute to clarifying other possible accumulation mechanisms. Further information should be expected from extention of these experiments.
外源性金属离子可渗透进入毛发并蓄积。金属离子的渗透和分布可通过电子微探针分析进行检测。不同阳离子的蓄积对周围溶液中其浓度的依赖性已通过原子吸收光谱法测定。蓄积程度取决于多种因素：所涉及离子的化学性质、其在溶液中的浓度和溶液的pH值、存在的阴离子的性质以及其他阳离子的性质和浓度。毛发中阳离子的分布可通过用蒸馏水洗涤而改变。详细讨论了目前针对毛发进行的物理化学实验对犯罪学、毒理学和环境保护的意义。结果表明，毛发中的锌含量主要源于内源性；此外，在发根处有强烈的蓄积现象。对蓄积机制的研究应有助于阐明其他可能的蓄积机制。通过扩展这些实验有望获得更多信息。
