头发是独特的微量元素蓄积物,它在相当短的时期内完成,不受体内代谢活动的影响,它在生长期间结合的无机盐与金属的含量不与其它组织保持动态平衡,其浓度分布可作为个体在特定时期内微量元素状况的指示物。有人研究人发中18种微量元素的分布特征,发现其与个体指纹情况一样具有独特 Hair is a unique accumulation of trace elements, it is completed within a relatively short period of time, not affected by the metabolic activity in the body, it is in the growth of the combination of inorganic salts and metals content with other organizations maintain a dynamic equilibrium, the concentration distribution Can be used as an indicator of the status of trace elements in a given period of time. Some people study the distribution of 18 kinds of trace elements in human hair and found that it has the same unique fingerprint as the individual
