Fig. 3 : μ-XRF maps of In, Fe, Ca, and Si in the rice rhizosphere of (a) Pc soil and (c) Tn soil, together with the corresponding optical microscopy images. (b–d) μ-XANES spectra from selected points within the map (POIs 1–5). (e) Schematic diagram of the mechanism for the release of In from In–Fe hydroxides and the formation of stable In-P/In(OH) 3 . Open circles represent the indium K-edge XANES spectra, and the solid lines are the best fits obtained using linear combination fitting. The soils used were collected from uncontaminated agricultural fields at the Tea Research & Extension Station (Pc soil, Typic Kandiudox) and Livestock Research Institute (Tn soil, Typic Dystrudept) in Taiwan.
