摘要
用Ｘ射线荧光分析法测定了１３０８例儿童和老年人头发中的Ｐｂ和Ｆｅ含量，结果发现儿童和老年人头发中Ｐｂ和Ｆｅ含量均比成年人高，其中婴儿的最高．儿童头发中的Ｐｂ、Ｆｅ含量随增龄而降低，而老年人发中的Ｐｂ、Ｆｅ含量随增龄而增加．本研究提示要特别警惕Ｐｂ对儿童的危害．
The contents of Pb and Fe in hair of 1308 children and the aged have been determined by XRF. It was found that the contents of both elements were significantly higher in hair of children and the aged than that of adults, and the highest for infants. Furthermore, the contents were decreased with age in childhood and increased with age in the senile, at least for old women. This work suggests that the most attention should be paid to the harmfulness of Ph to children, especially to infants.
