Periodic determinations are advisable in view of the
potential medium- and long-term risks associated with
lead contamination. A few clinical reports have suggested
that heavy alcohol intake may augment the
absorption and toxicity of lead. More likely explanations
for the apparent synergism are increased lead
exposure and nutritional deficiencies in some alcoholics
(Falcone, 1991). In addition to continuing efforts to
reduce the level of Pb contamination, current efforts to
reach an international agreement to stop the use of
metallic capsules together with continuous surveillance
of all processes during which contaminants can appear
are the most effective approaches to the prevention of
Pb contamination.
