Comparison of two acid extraction methods for determination of minerals in soils beneath to Larch Bolete (Suillus grevillei) and aimed to estimate minerals sequestration potential in fruiting bodies

Abstract

In this study a two simple and one-step extraction methods were compared for the evaluation of Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Rb, Sr and Zn accessibility in the soils to Larch Boletes (Suillus grevillei) mushrooms. Determination of chemical elements examined was by inductively coupled plasma-optical emission spectroscopy (ICP-OES). The extractable amounts of minerals from soil when analyzed by both extraction methods (25 % nitric acid “v/v” and 0.43 mol/L acetic acid solutions) correlated significantly with minerals content of Larch Bolete's fruiting bodies. Nitric acid solution used has shown its better capacity as stronger extractor elements than acetic acid. Nevertheless, the Larch Bolete more efficiently take-ups many metallic elements from soil (and sequester them in fruiting bodies), when compared to a leaching potential of both reagents examined, while for some elements availability seem to be limited or take-up and translocation is actively regulated by the mycelium.
