ASSESSING THE BIOAVAILABILITY AND BIOACCESSIBILITY OF TOTAL ARSENIC AND ARSENIC SPECIES IN ENVIRONMENTAL SAMPLES

ABSTRACT 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 bo...
