Figure 2
Spatial patterns of µ-XRF signals for As and selected soil matrix elements collected on the SRX beamline from a 10 µm × 10 µm sub-region (ROI-10a) of ROI-100 of the As(V) treated sand grain. Scale bars show that brighter colors represent greater natural log-transformed elemental fluorescence signals, generally corresponding to greater relative concentrations within imaged soil volumes (microsites).
