The aims of this study were to determine Cd and Pb contents in wild mushrooms from the eastern region of the “Green Lungs” of Poland (GLP), compare them to Cd and Pb contents in some popular species of cultivated mushrooms, and evaluate mushroom contribution to the daily intake of Cd and Pb. Trace elements were determined in 21 species of edible mushrooms: 18 species of wild mushrooms and 3 species of cultivated mushrooms.
The mean Pb contents in wild mushrooms ranged from 0.14 μg/g dry mass (DM) in Tricholoma portentosum to 2.61 μg/g DM in Russula vinosa, and for Cd from 0.10 μg/g DM in Russula heterophylla to 10.20 μg/g DM in Boletus chrysenteron. The Pb mean contents in cultivated mushrooms ranged from 0.03 μg/g DM in Agaricus bisporus to 0.12 μg/g DM in Lentinus edodes, and for Cd – from 0.09 μg/g DM in Agaricus bisporus to 1.20 μg/g DM Pleurotus ostreatus.
Wild mushrooms from the eastern GLP region is generally safe with regards to Pb intake. In contrast to Pb, the consumption of two species of wild mushrooms (Rozites caperatus and Boletus chrysenteron) may marginally exceed provisional tolerable monthly intake (PTMI) in temporary high consumers of these fungi, which pose a risk in Cd toxicity.
