A basic-type research study was conducted, with a non-experimental design, descriptive level, cross-sectional approach, using a convenience sampling method. Five samples were selected for each “corn” variety, totaling 20 samples. The technique employed was atomic absorption spectrophotometry, using a graphite furnace for lead and cadmium, and a hydride generator for arsenic. The obtained data were compared with the maximum limits allowed by MERCOSUR and CODEX ALIMENTARIUS standards.
