In addition to lead, the form of zinc in the Fe plaque of Phalaris arundinacea was also examined by fluorescence microtomography and EXAFS spectroscopy (Fig. 27, Hansel et al. 2001). Unlike lead, which was clearly associated with Fe (oxyhydr)oxides and inferred to be complexed to organic molecules, zinc was clearly correlated to manganese. On the basis of Mn-0 (2.20 A) and Zn-0 (1.96 A, 2.06 A, 2.08 A, 2.15 A) EXAFS distances, Mn was assumed to be speciated as rhodochrosite (MnC03) and Zn as hydrozincite (Zn5(0H)6(C03)2). While this study documented for the first time the combined use of fluorescence microtomography and EXAFS spectroscopy, and... 

The application of X-ray absorption spectroscopy (XAS), X-ray absorption nearedge structure (XANES), and EXAFS to tetrapyrroles that are not iron porphyrins is as yet relatively limited. Studies include EXAFS of 3-propenamide-zinc(II)-mcso-tetraphenylporphyrin complexes [201], XANES of vanadyl-phthalocyanine and vanadyl-meso-tetraphenylporphyrin [202], and XANES of iron(III)-phthalocyanine and its CO adduct [203].
