采用电感耦合等离子体质谱(ICP-MS)对22种食用菌78个子实体样品中的8种微量元素进行了测定。这些蘑菇是从一个农村地区的四个地点收集的，没有受到人类活动的污染。中位数(干物质)：砷1.45 mg kg~(-1)，钡1.41 mg kg~(-1)，钴0.28 mg kg~(-1)，铜47.0 mg kg~(-1)，Rb 130 mg kg~(-1)，银2.95 mg kg~(-1)，Tl 0.02 mg kg~(-1)，V 0.25 mg kg~(-1)。在Cantharellus cibarius和牛肝菌属和猪肝菌属的样品中也含有Rb。
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.
