    In this investigation, the concentrations of Arsenic, Cadmium, Lead, and Mercury were determined in quinoa (Chenopodium quinoa) samples sold in the markets of La Victoria, and it was established whether these concentrations were within permissible limits according to the parameters set by MERCOSUR, the European Union, and Brazilian legislation. The technique used was Atomic Absorption Spectrophotometry with Graphite Furnace and Hydride Generator. The average value of Arsenic in the samples was 0.35 ppm, with extreme values of 0.16 and 0.59, with 55% exceeding the maximum permissible limit (MPL) established by MERCOSUR. The average value of Cadmium in the samples was 0.18 ppm, with extreme values of 0.08 and 0.33, with 73% exceeding the MPL established by MERCOSUR and the European Union. The average value of Mercury in the samples was 0.005 ppm, with extreme values of 0.01 and 0.011, with 9% exceeding the MPL established by Brazilian legislation. The average value of Lead in the samples was 0.20 ppm, with extreme values of 0.11 and 0.36, with 45% exceeding the MPL established by MERCOSUR and the European Union. These results indicate that there is high contamination by Arsenic, Cadmium, and Lead in quinoa sold in the markets of La Victoria – January 2018.
