The aim of this study was to determine 19 elements contents and bioconcentration potential in fruiting bodies of Parasol Mushroom (Macrolepiota procera) collected from the Tucholskie Forest complex in Poland. Also discussed were Cd, Pb and Hg contents of edible caps in relation to the current regulatory standards. K, P and Mg were particularly abundant in caps and stipes, median values were 38-49, 13, and 1.6-1.6 mg/g dry weight, and followed by Ca, Na and Rb at 110-540, 44-240 and 20-50 μg/g dw, respectively. Concentrations of Al, Fe, Zn, Cu and Mn were from less than 50 to 180 μg/g dw, while concentrations of other elements were ∼l.0 μg/g dw or less. Cu, K, Ag, Cd, Na, Rb, Zn and Hg were bioconcentrated (BCF >1), while Al, Ba, Fe, Mn, Co, Sr, Pb and Cr were not bioaccumulated (BCF <1). Cd and Pb content of Parasol Mushroom's edible caps collected from some sites in the Tucholskie Forest exceed the maximum levels set in the EU for cultivated mushrooms.
本研究旨在测定波兰图霍尔斯基森林复合体中采集的伞菌（大青褶伞）子实体中的 19 种元素含量及其生物浓缩潜力。此外，还讨论了可食用菌盖中 Cd、Pb 和 Hg 的含量与现行监管标准的关系。K、P 和 Mg 在菌盖和菌柄中含量特别丰富，中值分别为 38-49、13 和 1.6-1.6mg/g 干重，其次是 Ca、Na 和 Rb，含量分别为 110-540、44-240 和 20-50μg/g dw。Al、Fe、Zn、Cu 和 Mn 的浓度低于 50-180μg/g dw，而其他元素的浓度约为 1.0μg/g dw 或更低。Cu、K、Ag、Cd、Na、Rb、Zn 和 Hg 被生物浓缩（BCF>1），而 Al、Ba、Fe、Mn、Co、Sr、Pb 和 Cr 则未被生物积累（BCF<1）。从图霍尔斯基森林的一些地点采集的伞菌可食用菌盖中的 Cd 和 Pb 含量超过了欧盟对栽培蘑菇规定的最高水平。
