DETERMINATION OF CADMIUM IN WHOLE-BLOOD AND URINE BY ZEEMAN ATOMIC-ABSORPTION SPECTROSCOPY

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 μg/l and 3.16 μg/l, respectively. Within-run precision studies for the urine analyses yielded relative standard deviations of 11.3% and 5.2% for 0.62 μg/l and 2.48 jug/l, respectively. The detection limit is 0.12 μg/1 in the diluted specimens. Thus, this methodology may be used to quantitate normal and toxic cadmium levels in whole blood and urine. © 1979.
