abstract = {This study provides information on mercury (Hg)
localization, speciation and ligand environment in edible
mushrooms: Boletus edulis, B. aereus and Scutiger pes-caprae
collected at non-polluted and Hg polluted sites, by
LA-ICP-MS, SR-μ-XRF and Hg L3-edge XANES and EXAFS.
Mushrooms (especially young ones) collected at Hg polluted
sites can contain more than 100 μg Hg g−1 of dry mass.
Imaging of the element distribution shows that Hg
accumulates mainly in the spore-forming part (hymenium) of
the cap. Removal of hymenium before consumption can
eliminate more than $50\%$ of accumulated Hg.Mercury is
mainly coordinated to di-thiols $(43–82\%),$ followed by
di-selenols $(13–35\%)$ and tetra-thiols $(12–20\%).$
Mercury bioavailability, as determined by feeding the
mushrooms to Spanish slugs (known metal bioindicators owing
to accumulation of metals in their digestive gland), ranged
from $4\%$ (S. pes-caprae) to $30\%$ (B. aereus), and
decreased with increasing selenium (Se) levels in the
mushrooms. Elevated Hg levels in mushrooms fed to the slugs
induced toxic effects, but these effects were counteracted
with increasing Se concentrations in the mushrooms, pointing
to a protective role of Se against Hg toxicity through HgSe
complexation. Nevertheless, consumption of the studied
mushroom species from Hg polluted sites should be avoided.},
