Many previous studies revealed a high ability of mushrooms to accumulate heavy metals from environment. This paper concerns the capacity of some wild macromycetes belonging to Russula genus to accumulate heavy metals in natural condition of pH (between 6.5 and 6.8) and the pattern of metal translocation in the fruiting body.
The studied Russula species are Russula virescens, Russula cyanoxantha, Russula foetens, and Russula nigrescens, which were harvested from forestry ecosystem from South Romania. The metal concentration in mushrooms and their substrate was established by EDXRF method.
The concentrations of iron (Fe), zinc (Zn), and copper (Cu) in the fruiting body depends on species and vary between 58.83-340.34, 19.70-99.62, and 5.03-9.37 mg/kg for Fe, Zn, and Cu, respectively. The bioaccumulation factor has subunit values for the three studied trace metals, which show the low capacity of these species of mushrooms to accumulate metals if the concentrations in soil increase over the normal threshold for these elements. The high values of translocation factor demonstrate the mobility of Fe, Zn, and Cu in the studied mushrooms.
许多先前的研究表明，蘑菇具有从环境中积累重金属的高能力。本文研究了一些属于红菇属的野生大型真菌在自然 pH 值（6.5 至 6.8 之间）条件下积累重金属的能力，以及重金属在子实体中的迁移模式。
所研究的红菇物种是绿菇、蓝黄红菇、毒红菇和黑红菇，它们是从罗马尼亚南部的林业生态系统中采集的。采用 EDXRF 法测定了蘑菇及其基质中的金属浓度。
子实体中铁（Fe）、锌（Zn）和铜（Cu）的浓度取决于物种，范围分别为 58.83-340.34、19.70-99.62 和 5.03-9.37mg/kg。生物积累因子对于这三种研究中的痕量金属具有亚单位值，这表明这些蘑菇物种在土壤中这些元素的浓度超过正常阈值时，积累金属的能力较低。高的迁移因子值表明 Fe、Zn 和 Cu 在研究蘑菇中的移动性。
