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.

Wild growing mushroom species have been characterized on the basis of several elements, rarely on the content of selected forms only (e.g., Falandysz et al 2007; Niedzielski et al 2013) or based on a multielemental analysis (e.g., Gucia et al 2012a; Kojta et al 2012)

Summary

Introduction

Responsible editor: Philippe GarriguesElectronic supplementary material The online version of this article (doi:10.1007/s11356-016-6760-8) contains supplementary material, which is available to authorized users.Mushroom consumption is generally high in Eastern Europe and Asia. Consumption of wild mushrooms collected from polluted areas may be associated with the risk of exposure to toxic elements ( Cd, Hg, Pb, and As) being introduced to the human body. The content of trace elements in wild growing mushroom species, both edible and inedible, has been reported in numerous articles (for an overview of data, see reviews of Kalač and Svoboda (2000), Kalač (2010), and Falandysz and Borovička (2013)) and some recent papers, e.g., Kaya and Bag (2010), Ayaz et al (2011), Sarikurkcu et al (2015), Yin et al (2012), or Mleczek et al (2015a). Mushrooms have been collected from both unpolluted (e.g., Falandysz et al 2012) and polluted areas
