[A new method for determination of cadmium in plasma (author's transl)].

Cadmium can be isolated from plasma by formation of negative charged iodide complexes bound to an anion exchange resin. Elution from the resin gives a cadmium solution with only a few interfering substances in an uniform matrix. Thus an undisturbed determination by flameless atomic absorption spectrometry is achieved. The mean of the natural cadmium level found in plasma was 1.9 +/- 0.8 ng/ml, within the normal range between 1.1 and 3.3 ng/ml.
