Fig. 1. X-ray fluorescence maps of selected metals in the intact LC biosolids sample. Area of a single map is 400 by 400 µm. The color scheme employed ranges from white–yellow for high fluorescence signal to blue–black for low fluorescence signal. Shading is relative across the single map. The eight markers noted as 1 to 8 represent locations for which µ-XANES analyses were conducted. The XANES spectra are presented in Fig. 6 and 7, and the XANES fitting is presented in Table 2.
