Quantitative maps of micro-element distribution in a mushroom (Boletus aereus) cap collected in the nearest vicinity of a Hg mine in Idrija, Slovenia. The cap consists of coloured cuticle (C), fleshy trama (T) and hymenophore (Hy) consisting of numerous vertically arranged tubes that carry basidia. Microelements like Zn and Se as well as potentially hazardous Hg accumulate in hymenium. On the Hg map, points where Hg-L3 XANES spectra were recorded are labelled (X). The best linear combination fit was obtained by merging XANES spectra recorded in plant and fungal models (Kodre et al., 2017) and HgSe (courtesy of Iztok Arčon). |
