这项研究旨在提供受欢迎和珍贵的野生牛肝菌中金属元素组成的基本数据，包括毒理上重要的Cd和Hg。我们调查了土壤基质作为这些金属来源的重要性。采用电感耦合等离子体原子吸收光谱分析和原子吸收光谱分析技术，测定了波兰普洛卡代尔地区香菇菌盖、菌柄和土壤表层(0~10 cm)中Al、Ba、Ca、Cd、Cu、Fe、Hg、K、Mg、Mn、Na、Sr、Zn等元素的含量。汞、铜、镉、锌、镁和钾具有生物富集性(BCF)和生物富集性(BCf；1)。具体地说，King Bolete对汞、铜和Cd(平均生物富集率分别为110、19和16)有较高的生物富集率，而其他元素被生物排除(BCF<；1)。在所调查的King Bolete蘑菇中，镉的平均含量为5.5+/-2.4 mg kg(-1)干重(Dw)，汞的平均含量为4.9+/-1.4 mg kg(-1)dw，两者的含量均较高。
This study aimed to provide basic data on the composition of metallic elements, including toxicologically important Cd and Hg, in popular and prized wild King Bolete mushrooms. We investigated the importance of soil substratum as a source of these metals. ICP-OES and CV-AAS were applied to determine the profile of Al, Ba, Ca, Cd, Cu, Fe, Hg, K, Mg, Mn, Na, Sr and Zn in caps and stipes of King Bolete mushroom and in the surface layer of soil (0-10 cm) from the Plocka Dale area of Poland. Hg, Cu, Cd, Zn, Mg and K exhibited bioconcentration factors (BCF) > 1. Specifically, Hg, Cu and Cd (mean BCFs for caps were 110, 19 and 16, respectively) were efficiently bioconcentrated by King Bolete, while other elements were bioexcluded (BCF < 1). Cadmium was present in the caps at mean levels of 5.5 +/- 2.4 mg kg(-1) dry weight (dw) and mercury at levels of 4.9 +/- 1.4 mg kg(-1) dw, both occurring at elevated concentrations in those King Bolete mushrooms surveyed.
