•Of the total grain As, 54% is composed of inorganic As.•Soils containing over 5.5mg As kg−1 have risk of accumulating grain [As] above WHO-permissible limit.•Higher radial oxygen loss, and formation of iron plaques reduce As uptake.•Once taken up, As- reduction, complexation and sequestration in va...
