摘　　要：在近 10年内按季度收集了同一个体人发样品 33份 ,指甲样品 41份和趾甲样品 39份。应用火焰原子吸收光谱法测定了人发、指甲、趾甲中镉的含量。绘制了含量值随时间 (年 )的变化曲线。获得了镉含量的波动范围 :人发 0 0 10 0～ 0 410 0 μg·g-1,指甲 0 0 2 95～ 0 5 314μg·g-1,趾甲 0 0 899～ 1 2 74μg·g-1。The human hair,fingernail and toenail were collected from one person quarterly for about ten years,respectively thirty three,forty one and thirty nine shares.The contents of traces cadmium in hair,fingernail and toenail have been determined by flame atomic absorption spectrometry,and the results were safisfactory.From a changing curve in human hair,fingernail and toenail cadmium by age,we found that the range of cadmium contents in hair was 0 010 0—0 410 0 μg·g -1 ,in fingernail 0 029 5—0 531 4 μg·g -1 ,in tenenail 0 0899—1 274 μg·g -1 ,respectively.In the changing curve there is a nonlinear characteristic.
