We studied concentrations of 34 essential and non-essential elements in samples of edible Bay Bolete (Imleria badia) mushrooms added by samples of the growing substrate and bioavailable fraction. The samples were collected from six forested sites affected differently by industrial pollution and underlain by compositionally contrasting bedrock: granite, amphibolite, and peridotite. In all cases, mushrooms behaved as a bioconcentrating system for elements such as Ag, K, P, Rb, S, and Se (BCF > 1) being a bioexcluding system for the rest of the elements analyzed (BCF < 1). Most analyzed elements displayed moderate to high within-mushroom mobility being accumulated preferably in the apical parts of the mushroom's fruiting body (TF > 1). The highest mobility was demonstrated by Cd and Cu. Sodium was the only element with significantly low mobility (TF < 1), and it accumulated preferably in the stipe. Imleria badia seems to be sensitive to the accumulation of elements such as As, Cd, and Pb from the atmospheric deposits. Specific geochemistry of the growing substrate was reflected to different extend in the accumulation of elements such as Ag, Cu, Rb, S, Al, Ca, Fe, Ba, and Na in the mushroom's fruiting bodies.
我们通过添加生长基质和生物可利用部分的样本，研究了食用红绒盖牛肝菌（Imleria badia）蘑菇样本中34种必需和非必需元素的浓度。样本采集自六个受工业污染影响程度不同且基岩成分各异的森林地点：花岗岩、角闪岩和橄榄岩。在所有情况下，蘑菇对于银、钾、磷、铷、硫和硒等元素表现为生物浓缩系统（生物浓缩系数>1），而对于其余分析元素则表现为生物排除系统（生物浓缩系数<1）。大多数分析元素在蘑菇体内具有中等至高的迁移率，优先积累在蘑菇子实体的顶部（转运系数>1）。镉和铜表现出最高的迁移率。钠是唯一迁移率显著较低的元素（转运系数<1），它优先积累在菌柄中。红绒盖牛肝菌似乎对大气沉积物中砷、镉和铅等元素的积累敏感。生长基质的特定地球化学特征在蘑菇子实体中银、铜、铷、硫、铝、钙、铁、钡和钠等元素的积累中得到了不同程度的反映。
