Contents of Metals in Some Wild Mushrooms: Its Impact in Human Health

Abstract

The concentrations of 7 metals (lead, cadmium, manganese, copper, nickel, silver, and chromium) were determined in 32 different species of wild mushrooms. The mushroom samples, which have been using for food and some medical purposes, were collected from Konya, an Inner Anatolian region of Turkey. The highest metal concentrations were determined as 39 mg/kg Pb and 3.72 mg/kg Cd in Trichaptum abietinum, 467 mg/kg Mn in Panaeolus sphinctrinus, 326 mg/kg Cu in Trametes versicolor, 69.4 mg/kg Ni in Helvella spadicea, 6.97 mg/kg Ag in Agaricus campestris, and 84.5 mg/kg Cr in Phellinus igniarius. The maximum contents are 1.52, 2.22, and 60.2 mg/kg in Pleurotus eryngii (for Pb), Amanita vaginata (for Cd), and Helvella leucomelana (for Cu), respectively. These results were compared according to the WHO/FAO standard.

Effect of Various Agro-Residues on Nutritive Value of Pleurotus eryngii (DC. ex Fr.) Quel. var. ferulae Lanzi

“…The level of manganese content of P. eryngii var. ferulae which was obtained from various compost medium is lower compared to an earlier published report (Dogan et al 2006).…”

“…Besides, the lowest copper level was found in natural wild sample ( Table 2). The reported copper values for P. eryngii was 16.5 mg kg -1 (Dogan et al 2006). Manganese contents of P. eryngii var.…”

“…On the other hand, no statistical difference was found for the manganese rate of mushroom samples which was obtained from WS + 20% RB and WS-CS (1:1) + 20% RB. The reported manganese content was 143 mg kg -1 in P. eryngii (Dogan et al 2006). The level of manganese content of P. eryngii var.…”

A screening study of elemental composition in 12 marketable mushroom species accessible in Poland

“…Numerous studies have addressed the chemical composition of wild species, including recently reported values of PGEs and REEs [14][15][16][17][18][19][20][21][22]. Cultivated specimens have usually been analyzed with respect to the content of some elements in selected mushroom species only [23][24][25][26], in general, those important to trade.…”

Laetiporus sulphureus – CHEMICAL COMPOSITION AND MEDICINAL VALUE

“…The estimated macroelements included potassium (18 500 mg kg −1 DM), calcium (4 200 mg kg −1 DM), magnesium (2 100 mg kg −1 DM) and sodium (285.0 mg kg −1 DM) [Ayaz et al 2011]. In turn, the contents of microelements were as follows: chromium (58.3 mg kg −1 DM), manganese (30.7 mg kg −1 DM), lead (24.5 mg kg −1 DM), copper (22.7 mg kg −1 DM), nickel (22.7 mg kg −1 DM), cadmium (0.68 mg kg −1 DM) and silver (0.26 mg kg −1 DM) [Doğan et al 2006]. Other studies confirmed the presence of aluminum (53.9 mg kg −1 DM), boron (16.4 mg kg −1 DM), cobalt (1.2 mg kg −1 DM) and tin (4.5 mg kg −1 DM) [Durkan et al 2011].…”
