Selected elements in fly agaric Amanita muscaria

Abstract

Concentrations of Ag, Al, Ba, Ca, Cd, Co, Cu, Cr, Cs, Fe, Ga, Hg, K, Mg, Mn, Mo, Na, Pb, Rb, Se, Sb, Sr, V, Tl and Zn have been determined in the whole fruiting bodies, as well as separately in caps and stalks, of fly agaric collected from three geographically distant sites in northern part of Poland. The elements were determined using ICP-MS, ICP-OES, HG-AAS and CV-AAS, respectively. For elements such as Al, Ba, Cr, Fe, Ga, Mo, Mn, Pb, Sb, Sr, Tl, and V concentrations were similar in the caps and stalks, respectively, and for K, Zn, Ag, Ca, Cd, Cu, Hg, Mg, Rb and Se were greater in the caps, while for Co, Cs and Na in the stalks. For Ag, Al, Ba, Ca, Cd, Co, Cr, Cs, Fe, Ga, Hg, Mn, Mo, Pb, Rb, Sb, Sr, Tl and V concentration in the caps showed spatial variations (P < 0.05), while for Cu, K, Mg, Na, Se and Zn was independent of the site. The elements such as K with median or mean in the caps between 37,000 and 43,000 μg/g·dm and Mg with 920 and 1,100 μg/g dm were most abundant. Next, within median values range from approximately 100 to 500 μg/g dm were such as Ca, Fe and Al, and in descending order they followed by Rb (100–400 μg/g dm); V, Na, Zn (50–200 μg/g dm); Cu, Mn (10–50 μg/g dm); Cd (10–20 μg/g dm); Se (5 μg/g dm); Ba (< 1–3); Cr, Ag, Pb, Sr (< 1–2 μg/g dm); Cs, Co, Hg (< 1–1 μg/g dm); Ga (< 0.5), Sb, Mo and Tl (< 0.1 μg/g dm).
