Abstract

The mushrooms represent an important contribution for the daily necessary for Fe, Mg and Zn of a human body. The trace metals concentrations were established by Inductively Coupled Plasma - Atomic Emission Spectrometry method. The results are varying with the analyzed species of mushrooms between 107.84 and 403.42 mg/kg for Fe, 367.14 to 1624.18 mg/kg for Mg and between 6.98 to 124.30 mg/kg for Zn. Reported to 100 g of fresh mushrooms these concentrations represent 14-121% for Fe, 2.5-21.9% for Mg and 1.2-44.7 for Zn from the daily necessary. The metals concentrations in fruiting body are in correlation one with each others, their absorption being species-dependent. The bioaccumulation factor has values under 0.1 for Fe, between 0.14 and 0.33 for Mg and between 0.04 and 0.77 for Zn with the highest values in Marasmius oreades and Calvatia excipuliformis species.
