Abstract
A survey is given over various methods for the determination of aluminum in biological materials. Graphite furnace atomic absorption spectrometry (GFAAS) is the most widely used technique since it is sufficiently sensitive and simple to operate. The limitations inherent in GFAAS-procedures are critically discussed. Reported results for aluminium in blood, serum and tissues differ largely showing that the determination of this element is subjected to large errors due to contamination during sample handling.
