Multielemental analysis of 20 mushroom species growing near a heavily trafficked road in Poland

Abstract

The aim of this work was to compare 10 mostly edible aboveground and 10 wood-growing mushroom species collected near a heavily trafficked road (approximately 28,000 vehicles per 24 h) in Poland with regard to their capacity to accumulate 26 trace elements (Ag, Al, As, Au, B, Ba, Bi, Cd, Co, Cr, Cu, Fe, Ga, Ge, In, Li, Mn, Ni, Pb, Re, Sb, Se, Sr, Te, Tl, and Zn) in their fruit bodies in order to illustrate mushroom diversity in element accumulation. All analyses were performed using an inductively coupled plasma optical emission spectrometry (ICP-OES) spectrometer in synchronous dual view mode. The aboveground species had significantly higher levels of 12 elements, including Ag, As, Pb, and Se, compared to the wood-growing species. An opposite relationship was observed only for Au, Ba, and Sr. The results of principal component analysis (PCA) and hierarchical cluster analysis (HCA) implied some new relationships among the analyzed species and elements. Of the analyzed mushroom species, lead content in Macrolepiota procera would seem to pose a health risk; however, at present knowledge regarding lead bioaccessibility from mushrooms is quite limited.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-6760-8) contains supplementary material, which is available to authorized users.

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

“…Compared to other species, the fruiting bodies G. frondosa were revealed to be the greater source of Ca, Cu, Fe, Mg, Mn, P or Zn [13,55,56] and lower in the case of, e.g., sum of REEs [22]. All of these elements play a pivotal role in various physiological processes while their deficiencies have been implicated in the etiology of number of disorders [57].…”

“…Mushrooms are well known to accumulate different elements, including potentially toxic metals and metalloids, and have been proposed as potential bioindicators of environmental pollution [13]. 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].…”

Phenolic Contents, Oxidant/Antioxidant Potential and Heavy Metal Levels in Cyclocybe cylindracea

“…15 Due to their saprotrophic properties, mushrooms can also be used as natural pollution indicators through element levels accumulated in their bodies due to substrate content during organic matter catabolism. 16,17 Elements such as Fe, Co, Cu, Mn, Mo, Sr, V and Zn that are required for living organisms in trace amounts can accumulate in living organisms over time and lead to undesirable consequences. 18 Thus, to determine the element levels of mushrooms is important to avoid the health problems that may arise due to their consumption via the food chain.…”

Comparison of multielemental composition of Polish and Chinese mushrooms (Ganoderma spp.)

“…Moreover, different species of the Ganoderma genus may require different conditions for growth and cultivation [29]. The element content in overgrown substrate or soil has been directly shown to affect their bioaccumulation in fruiting bodies [30]. It should also be noted that mushroom processing after harvest, particularly the conditions under which they are dried, can influence element content [31].…”
