Human thumbnails were analyzed for trace elements by instrumental analysis using thermal neutron activation technique. The average concentration of metals studied in clinically symptom-free adult female and male subjects were: zinc, 184 vs. 153 ppm; chromium, 6.8 vs. 4.2; selenium, 0.9 vs. 0.6; gold, 2.6 vs. 0.4; mercury, 1.9 vs. 0.4; silver, 0.7 vs. 0.3; cobalt, 0.07 vs. 0.04. A summary of literature reported concentration of metals in human nail is also presented.
采用热中子活化技术通过仪器分析对人类指甲中的微量元素进行了分析。在临床无症状的成年女性和男性受试者中所研究金属的平均浓度分别为：锌，184 ppm对153 ppm；铬，6.8对4.2；硒，0.9对0.6；金，2.6对0.4；汞，1.9对0.4；银，0.7对0.3；钴，0.07对0.04。还给出了文献报道的人类指甲中金属浓度的总结。
