本文研究了波兰基维蒂地区平菇和土壤表层（0-10 cm）中20种元素的含量及其相互关系。K、P、Mg、Ca和Zn是蘑菇中含量最丰富的元素。Fe、Mn、Na、Ni在菌柄中的含量高于菌盖，而Cd、Cr、Cu、Hg、Rb在菌盖中的含量最高。银，铝，钡浓度在帽和柄是相似的。伞菇子实体对Ag、Cd、Cu、Hg、K（菌盖中的生物富集系数为千分之100）、Na、P、Rb（50 < BCF < 100）和Mg、Zn（BCF > 10）的吸收和分离效率高，而Al、Ba、Ca、Co、Cr、Fe、Mn、Sr和Pb（BCF < 1）则被清除。产自波兰东北部地区农村林区的伞菇因其可食用菌盖中含有有毒的汞和镉而对人类健康产生卫生学关注，但其也富含必需的铜、铁，且其K、Mn和Zn含量也很高。
Concentrations and interrelationships of twenty elements were studied in parasol mushroom and in the top layer of soil (0-10 cm) from the area of Kiwity (Poland). K, P, Mg, Ca, and Zn were found to be the most abundant elements in the mushroom. Higher concentrations of Fe, Mn, Na, Ni occurred in stipes then in caps, while Cd, Cr, Cu, Hg, Rb dominated in caps. Ag, Al, and Ba concentrations in caps and stipes were similar. Parasol mushroom is efficient in up-take and separation of Ag, Cd, Cu, Hg, K (in caps, the bioconcentration factor is BCF a parts per thousand yen 100), Na, P, Rb (50 < BCF < 100), and Mg, Zn (BCF > 10) in its fruiting bodies, while Al, Ba, Ca, Co, Cr, Fe, Mn, Sr, and Pb are eliminated (BCF < 1). Parasol mushroom from rural forest area in the north-eastern region of Poland is of hygienic concern for human health because of toxic mercury and cadmium content in the edible caps, which are also rich in essential Cu, Fe, and their K, Mn, and Zn content is also high.
