Direct Determination of Cadmium in Blood and Urine by Zeeman Effect Electrothermal AAS

Abstract
Cadmium in blood and urine was determined using a Stabilised Temperature Platform Furnace (STPF) without matrix modification or addition of an ashing agent. Calibration was done using dilute acid standards whose concentrations had been confirmed against diluted NBS-SRM Trace Elements in Water. The procedure was validated with samples obtained from exposed workers and supplied by the Interlaboratory Comparison Program of the Toxicology Centre of Quebec, Canada.
