Eight trace elements were determined using ICP-MS in 78 fruiting body samples of 22 edible mushroom species. The mushrooms were collected from four sites in a rural area, unpolluted by human activity. Median values (dry matter) were as follows: Arsenic (As) 1.45 mg kg -1 , barium (Ba) 1.41 mg kg -1 , cobalt (Co) 0.28 mg kg -1 , copper (Cu) 47.0 mg kg -1 , rubidium (Rb) 130 mg kg -1 , silver (Ag) 2.95 mg kg -1 , thallium (Tl) 0.02 mg kg -1 and vanadium (V) 0.25 mg kg -1 . Higher trace element accumulation was observed in samples of Macrolepiota procera, Macrolepiota rhacodes, Lycoperdon perlatum, Lycoperdon gigantea and Xerocomus chrysenteron for As and Cu, and in samples of Cantharellus cibarius and of genera Boletus and Suillus for Rb.
