“…Our results are in essential agreement with most literature (Mlodecki et al 1965;Drbal and Kalač 1976;Tyler 1980;Lepšová and Mejstřík 1988;Vetter 1990Vetter , 2005Jorhem and Sundström 1995;Sesli and Tüzen 1999;Demirbaş 2001;Stijve et al 2001;Nikkarinen and Mertanen 2004). However, high concentrations (units or tens of ppm) reported by Ciusa et al (1982), Michelot et al (1998), Siobud-Dorocant et al (1999 and Yeşil et al (2004) are excessive and dubious. In our opinion, high Co values found by Yeşil et al (2004) cannot be explained by pollution factors (contaminated water, copper plant) because they were also found in wood-decaying macrofungi (e.g., Hypholoma fasciculare) and, moreover, concentrations of other heavy metals were not elevated.…”

“…However, despite the Se content of most ectomycorrhizal fungi being generally low, white-fleshed Boletus species, Amanita strobiliformis and Albatrellus pes-caprae are the most effective Se accumulators. Excessively high results reported for Fe (Stankevičiené 1996;Sesli and Tüzen 1999;Işiloğlu et al 2001;Turkekul et al 2004;Sesli 2006;Sesli and Dalman 2006;Sesli and Tuzen 2006;Tuzen et al 2007), Co (Ciusa et al 1982;Michelot et al 1998;Siobud-Dorocant et al 1999;Yeşil et al 2004) and Se (Michelot et al 1998;Siobud-Dorocant et al 1999) in macrofungi are doubtful; they might be caused by an incorrect methodology of analytical procedure.…”

Distribution of iron, cobalt, zinc and selenium in macrofungi

2007

Samples of wild growing ectomycorrhizal and terrestrial saprobic macrofungi (mushrooms) were collected from unpolluted areas and analyzed for their iron, cobalt, zinc and selenium content. Trace elements were determined using long-term instrumental neutron activation analysis. In total, 217 samples, including 87 species of ectomycorrhizal fungi and 43 species of terrestrial saprobes, were examined. Distribution of trace element contents in ectomycorrhizal and saprobic macrofungi was investigated; results are thoroughly compared with previously published data. Doubtful literature data and ability of macrofungi to accumulate/concentrate investigated elements are discussed. Hygrophoropsis aurantiaca was found to concentrate Fe and Russula atropurpurea was confirmed as an effective Zn-accumulating species. Distribution of Se in ectomycorrhizal species was obviously different from that in saprobic species; selenium contents were higher in saprobic species (mostly above 2 ppm).

“…Numerous previous studies have separately explored element content in fruiting bodies of wild and cultivated mushrooms [7,[32][33][34][35]. In both cases, increased levels of toxic or potentially toxic elements were reported [12].…”

The multi-elemental composition of 4 edible wild-growing mushroom species that commonly occur in Polish forests was compared to 13 cultivated mushroom species available in trade. A considerable variation in the macroelements content was revealed with cultivated species containing higher amounts of macroelements. The mean content of B, Co, Cr, Fe, Pb, Pr, Pt, Sb, Sm, Sr, Te, and Tm was higher in cultivated mushroom species, while the opposite was noted for Ba, Cd, Cu, Hg, La, Mo, Sc, and Zn. Selected cultivated forms exhibited increased content of Al (F. velutipes), As (H. marmoreus, F. velutipes), Ni (P. ostreatus, A. polytricha, H. marmoreus), and Pb (P. ostreatus, A. polytricha, F. velupites, and L. edodes). Wild-growing species, B. boletus, I. badia, and S. bovinus contained high Hg levels, close to or exceeding tolerable intakes. Compared to cultivated mushrooms, they also generally revealed a significantly increased content of Al (with the highest content in B. edulis and I. badia), As and Cd (with the highest content in B. edulis and S. bovinus in both cases). In turn, the cultivated mushrooms were characterized by a higher content of Ni (particularly in A. bisporus) and Pb (with the highest content in P. eryngii). The exposure risks may, however, differ between wild and cultivated mushrooms since the former are consumed seasonally (although in some regions at a high level), while the latter are available throughout the year. Both cultivated and wild-growing mushrooms were found to be a poor source of Ca and Mg, and only a supplemental source of K, Cu, Fe, and Zn in the human diet. These results suggest that mushrooms collected from the wild or cultivated, should be consumed sparingly. The study advocates for more strict monitoring measures of the content of toxic metals/metalloids in mushrooms distributed as food, preferentially through the establishment of maximum allowance levels not limited only to a few elements and mushroom species.

“…The method is linear in that the new variables are a linear combination of the original ones (9). Correspondence factor analysis (CFA) (10) was also tried because it had been successfully used on similar data matrixes (4,(11)(12)(13). CFA is primarily a technique for displaying the rows and the columns of a two-way contingency table as points in corresponding low-dimensional vector spaces.…”

The elemental analysis of 86 honeys sold in France was performed with an inductively coupled plasma atomic emission spectrometer in order to measure significant concentrations of Ag, Ca, Cr, Co, Cu, Fe, Li, Mg, Mn, Mo, P, S, Zn, Al, Cd, Hg, Ni, and Pb. Principal component analysis, correspondence factor analysis, and hierarchical cluster analysis were used to rationalize and interpret the analytical data. Crude relationships were found between the elemental profiles of the honeys and their botanical origin. Some honeys were highly polluted by heavy metals and/or other xenobiotics. Explanations for these contaminations are proposed.
