摘　　要：本工作按性格类型、年龄段、抽烟与否、染发与否、长期食用外卖与否对采样人群进行分组,用X荧光分析法测量了人发中重金属元素(Zn、Cu、Fe)的含量,分析了重金属元素在不同人群头发中的含量差异。结果表明:精确型性格人群头发内Zn元素含量显著高于外向型性格人群;头发内Zn元素含量随着人类年龄的增加大致呈现出先增加后减少的趋势,在20~30岁年龄段达到峰值;吸烟者和染发者头发内Zn元素含量偏低,Cu、Fe元素含量偏高。This study aims to examine the differences of heavy metal content among different human s hair. The hair samples are measured by Energy Dispersive X-ray Fluorescence analysis (ED-XRF), which are divided into 15 groups according to volunteers personality type, age and lifestyles. The results reveal: Accuracy personality people show significant higher content of Zinc in the hair than people from extroversion personality group;With the age increasing, the content of Zinc increases until forming a peak at 20-30 age group, and then the content of Zinc is falling down;It is found that the people smoking cigarette and having hair dyeing have higher Copper and Iron and lower Zinc on average but not significant.
