摘要
研究了东北辽源地区 5～ 2 0岁不同年龄段的青少年 ,1 1 4 7例头发中六种微量元素含量随着年龄增大的变化规律 ;既从单因素角度 ,又从多元素群体、多元统计分析方面研究了不同年龄段青少年头发元素含量的性别差异 ,相关系数差异及其群体微量元素谱图的差异。
The changes of hair trace element levels were analysed among 1147 young people aged 5～20 as their growths.The results showed that there were various differences in trace elements levels along with the sex,age and group.
