Silver content of wild-grown mushrooms from northern Poland.
Wild-grown and mostly edible species of higher mushrooms collected in 1989-1992 from the districts of Gdańsk, Elblag and Piła (northern part of Poland) have been investigated with regard to their silver content. In total, 527 samples including 25 mushroom species of six families (Agaricaceae, Boletaceae, Cantharellaceae, Hygrophoraceae, Coprinaceae and Russulaceae) were examined. Among the fungi examined only Agaricus campestris and A. augustus were heavy bioaccumulating species and showed the highest concentrations of 35 mg Ag/kg dry weight (1.1-150) and 2.0-6.9 mg/kg, respectively. Silver concentrations exceeding 1.0 mg/kg dry weight were noted in Boletus aestivalis, Lepista nuda, L. personata, and in some specimens of B. edulis, Leccinum scrabum, L. vulpinum, Cantharellus cibarius and Coprinus comatus.
