Direct measurement of lead and cadmium in blood and urine by electrothermal atomic absorption spectrometry with deuterium background correction (D2-AAS) is prone to severe matrix and spectral interferences. We overcame these effects by coating the L'vov platform with ammonium molybdate, reducing the atomization time, introducing a post-atomization cooling step, carefully selecting ashing and atomization temperatures, and using an appropriate procedure for matrix modification. To determine Pb and Cd in blood and urine, we used matrix-matched calibration curves. With the proposed procedure for sample preparation, both Pb and Cd in whole blood can be determined in the same diluted sample. Results obtained by D2-AAS correlate closely with those by Zeeman-corrected AAS. Detection limits (mean blank + 3 SDblank) for Pb in urine and blood were 4 micrograms/L. For cadmium, the detection limits were 0.4 and 0.1 micrograms/L for urine and blood analysis, respectively. Between-run CVs were less than 5.0%.
