Abstract
Among the additives used in the formulation of food packaging, specially in plastics packaging, are
included substances which provide coloration, classified as coloring or pigments according to their solubility
or insolubility in the polymer. The addition of these substances into packaging materials satisfies an
esthetic and technological requirements. The metals eventually present as contaminants in colorings and pigments for packaging can migrate to food causing health damages. The purpose of the present study was to verify and to control the levels of lead, cadmium and zinc, in these products and to validate the
analytical methodology in accordance to Mercosul Regulations (Resolução Nº105/99 ANVISA/MS). The
quantification of these metals was performed by flame atomic absorption spectrometry technique. Of 407
samples, 5% were in disagreement with the legislation limits. The high levels of those metals found in
analyzed samples justify the continuous control that should be done in this kind of products.
