Analysis of some nutritive and toxic elements in four species of wild edible mushrooms.

Wild mushrooms have been gathered as a food source by humans for thousands of years and the practice remains popular all over the world today. The purpose of this study was to investigate the presence of 22 elements in four species of wild edible mushrooms common to northeastern Oregon and to quantify their concentrations. Elements investigated include K, P, Al, As, B, Ba, Ca, Cd, Co, Cu, Fe, Hg, Mg, Mn, Mo, Ni, Pb, S, Se, Si, Zn. Concentration values were then compared to those obtained from a cultivated species (Agaricus bisporus) that is commonly found in supermarkets. These values were also compared to daily intake recommendations by the Institute of Medicine to determine if these wild mushrooms are a good dietary source of nutritive elements and/or if they contained toxic concentrations of them. Analysis of mushrooms was performed using ICP-MS. Twelve of the 22 elements were not detected in any of the mushroom species (As, B, Ba, Cd, Co, Cu, Hg, Mo, Ni, Pb, S, Se), while Mn and Si were found in some species but not others.
