Mercury in Russula mushrooms: Bioconcentration by Yellow-ocher Brittle Gills Russula ochroleuca.

The purpose of this study was to examine the contamination and bioconcentration potential of mercury (Hg) in Yellow-ocher Brittle Gills known also as Yellow-ocher Brittle Gill or Common Russula (Russula ochroleuca) mushroom. Matured fruiting bodies of this fungus and soil samples were collected at ten spatially distant unpolluted sites in the northern part of Poland in 2004-2008. Total Hg content of fruiting bodies and soil were determined by cold-vapour atomic absorption spectroscopy (CV-AAS).

[Mercury in the country's Bay Bolete (Xerocomus badius) mushrooms].

Total mercury content have been determined in fruiting bodies of Bay Bolete and its underlying soil substrate collected from three spatially distant sites of the country--outskirts of the Mojusz village (Sierakowice Commune, Pomorskie Voivodeship), at the forest inspectorate Turek (Wielkopolskie Voiv.) and near the Lipie village at the Starachowickie forests (Swietokrzyskie Voiv.).
