Resumen:
In the last years, amaranth (Amaranthaceae) had been proposed as new food due to its nutritional properties (i.e. aminoacid, protein, lipidic and carbohydrates contents). However the determination of toxic elements was less studied in amaranth seeds. For this reason, the concentration of As, Cr and Pb was determined in three species of amaranth seeds: A. hypochondriacus, A. cruentus and A. dubius, which were harvested in Argentina ? provinces of La Pampa and San Luis-. The determinations were carried out by inductively coupled plasma optic atomic spectroscopy (ICP-OES). Evaluation of accuracy was carried out by standard addition method. The results show that, for the three species, Cr and As were present in low concentration. However, the concentration of Pb was high, at least, two times the maximum allowed -10 µg g-1- by the World Health Organization (WHO). As conclusion, the high concentration of Pb present in amaranth seeds from Argentina indicates that Pb should be considered in these amaranth species to avoid undesirable consequences for the human health in the population that consume these seeds.
