Metal concentration of wild edible mushrooms in Soguksu National Park in Turkey

Abstract

Twelve varieties of fruiting bodies of wild edible mushrooms collected in 2002 from Soguksu National Park, Ankara, Turkey were analysed for Pb, Cd, Zn, Fe, Mn, Cu, Cr, Ni, and Co contents by inductively coupled plasma optical emission spectrometry (ICP-OES). Dried samples were dissolved by microwave digestion. The contents of trace metals in the mushroom samples were found in the ranges: 0.7–4.2, 0.31–54.2, 29–146, 138–1714, 10–77, 6–187, not detected–21.6, 0.7–4.2 and not detected–5.2 mg kg −1 for Pb, Cd, Zn, Fe, Mn, Cu, Cr, Ni and Co, respectively. The levels of Pb and Cd analysed in all edible mushroom samples except Agaricus arvensis and Ramaria obtusissima for Cd were found to be lower than the legal limits.
