内蒙古蒙、汉大学生头发中四种微量元素的含量与发育水平关系的研究

用原子吸收分光光度法测定了内蒙古520名蒙、汉大学生（19～22岁）头发中锌、铜、铁、锰元素的含量。比较结果：蒙族女生发铜、铁元素高于蒙族男生，差异有显著意义；汉族男女生间差异无显著性；蒙、汉族女生间差异无显著性。蒙族男生发铜元素含量低于汉族男生，差异有极显著意义；蒙、汉族女生差并无显著性。经相关分析及身高、体重不同发育水平组的发锌元素的含量的均值比较结果表明，发锌元素含量与身高、体重发育水平有关。

Contents of Four Trace Elements in Hair and Physical Development in Mongolian and Han Students in Inner Mongolian

Determination of Zn. Cu. Fe and Mn in hair was performed in 520 students of Mongolian and Hen nationalities, aged 19~22 years. in Inner Mongolian with atomic absorption spectropho to metry. mir Cu and Fe in Mongolian girl students were significantly higher than those in Mongolian boy students. wkereas therewes no difference between Han boy students and girl students in hair Cu and Fe. Tbe content of Cu in the bair of Mongolian boy students was lower than that of Han boy students. There was no difference in hair Cu between Mongolian girl students and Han glrl students. Correlation analysis and comparison of mean Zn concentration among different development groups confirmed that hair Zn concentration was associated with ths development levels of both height and weight.
