Abstract
Methods for the measurement in the aqueous phase and organic phase (MIBK) after extraction with APDC of lead by atomic absorption spectrometry in beverages and in the biological fluids of humans assumed to be poisoned were studied and applied. The detection limits obtained were 0·045 and 0·025 ppm. Correlations were obtained between the content of lead in beverages and the use of vitrified earthenware containers and between the content of lead in beverages and in the biological fluids of the consumers.
