µXRF elemental maps (arbitrary unit) showing the distribution of Y, Fe, Mn, Zn and Ca in a root cross section of wild Saxifraga paniculata grown in Y doped soil; (a) shows the scanned region and the outline of the root; (b–f) show elemental maps of K-emission lines; X-ray spot-size: 0.4 µm; Counting-time: 40 ms/px; Gap-size: 100 µm × 60 µm; Contrast: 0.3% saturated pixels; Maximum pixel values in brackets.
