Mercury bioaccumulation by wild edible mushrooms

Mercury (Hg) contents was determined in ten species of edible mushrooms in Zrin mountain, Croatia. The analyses of mercury were carried out by AAS mercury analyzer (Atomic Adsorption Spectrophotometer). The greatest mercury mean concentration of 2.28 mg kg-1 was determined in ectomycorrhizal species Boletus edulis. In terms of the anatomical parts of the fruiting body (capstipe), a considerably greater concentration of mercury was found in the cap then in other parts forall mushroom species. According to calculated bio-concentration factors, all the examined species were found to be bio-accumulators of mercury. The possibility of toxicological effects on human health consumption of investigated species are negligible.
