Resumen

PIZARRO, ISABEL; ROMAN, DOMINGO; GOMEZ, MILAGROS  y  PALACIOS, M. ANTONIA. ASSESSING THE BIOAVAILABILITY AND BIOACCESSIBILITY OF TOTAL ARSENIC AND ARSENIC SPECIES IN ENVIRONMENTAL SAMPLES. J. Chil. Chem. Soc. [online]. 2017, vol.62, n.3, pp.3653-3657. ISSN 0717-9707.  http://dx.doi.org/10.4067/s0717-97072017000303653.

Studies on the bioavailability of As, of impacted vegetables; and As bioaccesibility in the edible parts of carrots (daucus carota), beets (beta vulgaris) and quinoa (chenopodium) growing in polluted soils thought “in vitro” gastrointestinal process; the As speciation both in the edible parts of vegetables and in their gastrointestinal extracts have been performed. Elemental analysis and As speciation have been performed by ICP-MS and LC-ICP-MS, respectively. The Arsenic recovery after the in vitro gastrointestinal digestion was from 98, 90 and 40% for carrots, beets and quinoa, respectively; with no significant transformation of original As species. These studies provide a clearer understanding of the impact that As and other contaminant elements may present in the population of this high polluted Chilean region.

Palabras clave : arsenic speciation; bioaccesibility; bioavailability; vegetables; gastrointestinal digestion.
