Direct determination of cadmium in whole blood and urine can be achieved using Zeeman effect flameless atomic absorption spectroscopy. Within-run precision studies for whole blood cadmium determinations gave relative standard deviations of 11.3% and 6.3% for 0.53 micrograms/l and 3.16 micrograms/l, respectively. Within-run precision studies for the urine analyses yielded relative standard deviations of 11.3% and 5.2% for 0.62 micrograms/l and 2.48 micrograms/l, respectively. The detection limit is 0.12 micrograms/l in the diluted specimens. Thus, this methodology may be used to quantitate normal and toxic cadmium levels in whole blood and urine.
使用塞曼效应无火焰原子吸收光谱法可直接测定全血和尿液中的镉。全血镉测定的批内精密度研究表明，对于0.53微克/升和3.16微克/升的浓度，相对标准偏差分别为11.3%和6.3%。尿液分析的批内精密度研究得出，对于0.62微克/升和2.48微克/升的浓度，相对标准偏差分别为11.3%和5.2%。稀释样本中的检测限为0.12微克/升。因此，该方法可用于定量全血和尿液中正常及有毒的镉含量。
