Results from least-squares linear combination fitting of each samples XANES spectra in comparison to standard selenium compounds.The regions where the spectra were collected are indicated in Figure 1.SeO32−: selenite; Se(GSH)2: seleno-diglutathione, C-Se-C: methyl-selenocysteine, seleno-methionine or seleno-cystathionine.Se0: red or gray elemental Se. SS: normal sum of squares (quality of fit; 0 = perfect fit); nd: compound not detectable. Additional standard compounds included in the fit but not detected in any location were selenate, seleno-cystine and seleno-cysteine. Note: fractions do not always add up to exactly 100% because the margin of error can be up to10%.
