摘　　要：用X射线荧光分析法(XRF)测定了186例上海市80岁以上老人头发中的Ca及Mn、Fe、Cu、Zn、Pb、Sr等微量元素的含量,观察到发中Fe、Pb、Zn含量随年龄增长而增加,而Cu/Fe、P比值似可作为衡量衰老的一种指针。The Ca, Mn, Fe, Cu, Zn, Pb and Sr contents in hair of the aged people over 80 years old have been determined by using Pu-238 source activated X-ray fluorescence ana-lysis method (XRF). The results indicated that the contents of Fe, Pb, and Zn in hair increased with age, and that the ratio of Cu/Fe, Pb, which might be useful in estimating aging process, decreased with age. The clinical significance of these elements were discus-sed.
