Seventeen elements: Al, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, V and Zn (macroelements and trace elements) have been investigated by Atomic Spectrometries on a particular wild edible mushroom collected in the central region of Argentine during two different years in the same season. The metal content profile in Suillus granulatusSuillus granulatus samples is given. The found quantities of Na, K, Ca, Mg, Fe, P, V and Al were 0.40, 10.84, 0.48, 0.30, 0.57, 4.24, 0.18 and 1.23 g/kg dry weight respectively. The levels of Li, Cu, Zn, Cd, Co, Ni, Cr and Mn were 0.98, 23.02, 22.30, 0.26, 0.16, 1.17, 0.90 and and 28.75 mg/kg dry weight respectively. Pb was not detected at the investigated levels. The results indicate that the levels of metals in the analyzed samples are not considered to be a health risk. In order to demonstrate the validity of our method, a recovery study was carried out with acceptable results.
