Abstract
The aim of this study was to examine the status of some trace metals accumulated in the flesh of Suillus grevillei mushrooms collected from the same site over two successive years. Total Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Rb, Sr and Zn contents of fruiting bodies were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES) with ultrasonic cross-flow nebuliser. A difference (p < 0.05) was found in the contents of Cd, Cr, Cu, Fe, K, Na, Ni, Pb, Rb and Sr in caps and Fe, Na, P and Rb (p < 0.05) in stipes (Ag, Cd, Co, Cr, Ni and Pb were not determined in stipes). Natural fluctuations in trace elements’ content of Suillus grevillei collected from the same site over time is a variable that needs to be considered when assessing minerals’ nutritional status of mushrooms.
