G = gastric phase and G+I = gastric followed by intestinal phase; both are shown for arsenic since both phases are relevant, but only the gastric phase results are shown for lead since these are the highest results. N/a = not applicable, because bioaccessible concentration detection limit is greater than total concentration, both bioaccessible concentration and total concentration are below detection, or total concentration is below detection.
