本文用中子活化分析法测定了正常人表皮中As、Au、Br、Ca、Cd、Co、Cr、Cs、Cu、Fe、Hg、K、La、Mo、P、Rb、Sb、Sc、Se、W、Zn等21种元素的含量。考虑到这些元素在平衡研究中可能的重要性，计算了这些元素通过脱屑的皮肤损失。对于大量元素Ca、K和P，计算的每日损失被认为是可忽略的。然而，对于某些微量元素，损失可能是可观的。每日脱落的铁可能高达每日尿铁排泄量的1/4;钴，铜和锌的相应分数为1/10。
The content of 21 elements (As, Au, Br, Ca, Cd, Co, Cr, Cs, Cu, Fe, Hg, K, La, Mo, P, Rb, Sb, Sc, Se, W and Zn) in normal human epidermis was determined with the aid of neutron activation analysis. The dermal loss of these elements via desquamation was calculated, in view of its possible importance in balance studies. For the bulk elements Ca, K and P, the calculated daily loss is considered to be negligible. For some of the trace elements, however, the loss may be appreciable. The daily loss of Fe by desquamation may be as much as 1/4 of the daily urinary Fe excretion; the corresponding fraction for Co, Cu and Zn is 1/10.
