Selected elements in Brown Birch Scaber Stalk Leccinum scabrum

Abstract

A survey of 26 metallic elements and metalloids such as Ag, Al, Ba, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Rb, Sb, Se, Sr, Tl, V and Zn was carried out using ICP-MS, ICP-OES, HG-AAS and CV-AAS in the caps and stalks of edible mushroom Brown Birch Scaber Stalk collected from two lowland and one mountain sites in Poland. Ag, Al, Cd, Cr, Cs, Cu, Fe, Hg, K, Mg, Mo, Pb, Rb, Se, V and Zn occurred in greater concentration in the caps than stalks of Brown Birch Scaber Stalk, and opposite situation was for Tl and Na. Brown Birch Scaber Stalk collected from the site in Sudety Mountains did contain Al, Ba, Cs, Fe, Ga, Ni, Pb, Sr and V in significantly greater concentration when compared to specimens collected from the lowland sites, and what imply on significance of geological origin and/or soil substrate pollution impacting on mineral composition of this mushroom species. The results provide useful environmental and nutritional baseline level information on mineral composition of Brown Birch Scaber Stalk from unpolluted sites.

210Po, 210Pb, 40K and 137Cs in edible wild berries and mushrooms and ingestion doses to man from high consumption rates of these wild foods

“…In support of this hypothesis it should be noted that higher levels of selenium have been reported in caps of mushrooms than in stipes of various fungi (e.g. Falandysza et al, 2007;Stijve, 1977), with the same observation reported for 210 Po (Skwarzec and Jakusik, 2003;Vaaramaa et al, 2009). Furthermore, in the study of Borovi cka and Randa ( the highest levels of selenium in a wide selection of fungi were observed in Boletus spp., a genus of fungi that has been previously identified as strong accumulators of 210 Po (Skwarzec and Jakusik, 2003).…”

Lead in edible mushroomsLevels and bioaccumulation factors

“…For L. scabrum [20], lead content of the caps on the average was < 1.0 g/g dm, and the stalks were nearly 3-fold less abundant in this element, except in samples collected at distance around 400 m off a lead smelter, that reached median value of 3.0 g/g dm and up to 16 g/g dm. Our values (1.25 mg/kg dw) were inferior to these contents.…”

Cadmium in edible mushrooms from NW Spain: Bioconcentration factors and consumer health implications

“…In contrast to green plants, mushrooms consist of large concentrations of some metals such as Cd, Pb, and Hg, so for the evaluation of a possible hazard to human health due to the ingestion of mushrooms, a great effort should be made (Kala c and Svoboda, 2000;Kula et al, 2011;Peña-Fern andez et al, 2014). In order to find metal contents in the fruiting bodies of a large number of species of edible mushrooms, many studies have been done (Cocchi et al, 2006;Falandysz et al, 2007Falandysz et al, , 2008aKala c, 2010;Li et al, 2011;Mendil et al, 2004;Svoboda et al, 2006;Yamaç et al, 2007;Zhu et al, 2011).…”

“…Ag, As, Cd, Hg, Pb Melgar et al, 1998). Many mushrooms that emerge in background areas due to species-specific features can also absorb and sequester in their fruiting bodies certain metals and metalloids to high concentrations (Falandysz et al, 2007(Falandysz et al, , 2008a(Falandysz et al, , 2008bGucia et al, 2012). The capacity of mushrooms (Macromycetes) to absorb and sequester metallic elements or metalloids in their fruiting body can be assessed by the bioconcentration factor (BCF) values of the elements (García et al, , 2013Kojta et al, 2012;Melgar et al, 2009Melgar et al, , 2014Falandysz et al, 2015).…”
