The determination of thallium in human hair samples by differential pu
lse anodic stripping voltammetry after microwave digestion has been pr
esented. Hair samples were collected from the vertex of the scalps of
donors who were employed in factories manufacturing lead-acid batterie
s. The results show that permanent contact with an environment pollute
d by lead makes it possible to absorb very large amounts of thallium,
which is present in this environment only as an impurity of lead. The
study also shows that absorption of thallium by workers is a few times
'better' than that of lead.
