Macro- and Microelement Contents of Fruiting Bodies of Wild-Edible Mushrooms Growing in the East Black Sea Region of Turkey

Eleven different wild-edible mushroom species growing in the Black Sea region of Turkey were analysed for their element content. Specimens of mushrooms were gathered in Trabzon, Giresun and Ordu and analyzed for 31 elements by ICP-OES, four of which (Be, Sb, Te and Ti) were not detected. Whereas some minerals including Ag, As, Cd, La, Mo, Pb, Se, Y and Zr were detected in just a few mushroom species, another 18 minerals were found in all 11 species. All element concentrations were expressed on a dry weight basis (d.w.). With regard to nutritionally important amounts of essential and trace minerals, the element content (μg/g d.w.) of mushroom samples ranged from 21800 39800 for K, 2590 14000 for P, 268 1600 for Ca, 561 1210 for Mg, 74 829 for Fe, 11.2 321 for Cu, 36.2 241 for Zn, 14.1 76.5 for Mn and 0.13 2.85 for Co. Small amounts of toxic metals such as As, Cd and Pb were found in all 11 mushroom species. Laccaria laccata contained a large amount of As (145 μg/g d.w.). These results show that the investigated mushrooms can be a useful component for human diets because of their high content of many essential minerals and trace elements and low content of toxic metals.
