title: A rapid direct determination of cadmium in blood by anodic stripping voltammetry.
abstract: This paper describes a rapid, sensitive anodic stripping voltammetry (ASV) method for measuring quantities of cadmium in blood. An advantage of this method is the minimal sample preparation required, using a metal-exchange reagent. A sensitivity of 4 nmol/l can be obtained. The results correlate with those obtained by atomic absorption spectroscopy. Within-run, the coefficient of variation (CV) was 8.9% at a cadmium concentration of 32 nmol/l. Between run CV was 5.4% at 37 nmol/l. The reference interval for blood cadmium concentration was 5-60 nmol/l for non-smokers and 5-85 nmol/l for cigarette-smokers. This method of cadmium analysis shows that ASV is a rapid, sensitive method for determination of blood cadmium in the normal range.
