微量元素与人体健康有着密切的关系,人头发、指甲中微量元素的组成在诊断疾病、监测环境污染等方面是个有价值的参考指标。有关人头发中微量元素的分析报道较多,而指甲中微量元素的分析报道则甚少。为了探讨头发与指甲中微量元素含量之间的差异和规律,以求在两者间选择较好的生物检测材料, Trace elements and human health are closely related to human hair, nails in the composition of trace elements in the diagnosis of disease, monitoring of environmental pollution is a valuable reference index. There are many reports on the analysis of trace elements in human hair, while there are few reports on the analysis of trace elements in nails. In order to explore the differences between hair and nails in the trace elements and the law, in order to choose between the two better biological testing materials,
