The oxidation states of elements in OS and ACP ashes were determined using
XANES. It was found that Cr and As in the oxidation states [Cr.sup.+3] and [As.sup.+3] in OS were converted to [Cr.sup.+6] and [As.sup.+5] in ACP ashes, respectively (Fig.
Fluorescence maps have been quantitatively fitted and analysed with PyMca [36], while
XANES spectra have been analysed with Athena [37].

Additionally, the forms of sulfur present in the soils were determined using X-ray absorption near-edge structure (
XANES) spectroscopy.
