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 satisfactory. From a changing curve in human hair, fingernail and toenail cadmium by age, we found that the range of cadmium contents in hair was 0.0100-0.4100 microgram.g-1, in fingernail 0.0295-0.5314 microgram.g-1, in tene-nail 0.0899-1.274 micrograms.g-1, respectively. In the changing curve there is a nonlinear characteristic.
在大约十年的时间里，每季度从同一个人身上分别采集头发、手指甲和脚趾甲，各采集了三十三份、四十一份和三十九份。采用火焰原子吸收光谱法测定了头发、手指甲和脚趾甲中痕量镉的含量，结果令人满意。从头发、手指甲和脚趾甲中镉含量随年龄变化的曲线可以看出，头发中镉含量范围为0.0100 - 0.4100微克·克⁻¹，手指甲中为0.0295 - 0.5314微克·克⁻¹，脚趾甲中为0.0899 - 1.274微克·克⁻¹。在变化曲线中存在非线性特征。
