The concentrations of Cu, Zn, Fe and Mg in fingernails of 212 normal children, 109 males and 103 females, 6--11 years old, were determined by atomic absorption spectroscopy. A wide scatter of results in all trace element determinations in fingernails was found. Nevertheless, it was noted that the petrographical composition of the region influences the trace element concentration in fingernails. An age variation was observed for Cu and Fe. Nail concentrations of the same trace elements were significantly higher in male than in female children.
采用原子吸收光谱法测定了212名6至11岁正常儿童（109名男性和103名女性）指甲中铜、锌、铁和镁的含量。结果发现，指甲中所有微量元素测定结果的离散度都很大。然而，值得注意的是，该地区的岩相组成会影响指甲中的微量元素浓度。观察到铜和铁存在年龄差异。同一微量元素的指甲含量在男性儿童中显著高于女性儿童。
