The atmospheric fallout impact on Po and Pb content in fruitbodies of wild growing mushrooms collected from different environments were investigated. The samples of morphologically different mushroom species, namely bay bolete (Imleria badia (Fr.) Vizzini), slippery jack (Suillus luteus (L.) Roussel), fairy ring mushroom (Marasmius oreades (Bolton) Fr.) and common earthball (Scleroderma citrinum Pers.) with their mycelium and soil substrate were collected. Their fruitbodies were separated into cap skin, cap flesh and stem. Also mycelium and soil substrate were collected. The results showed the highest Po and Pb activity concentrations were found in Marasmius oreades cap skin: 3.20 ± 0.12 and 21.1 ± 0.5 Bq kg ww, respectively, which constituted 31.2 and 78.7% of their content in the total fruitbody mass. In the case of open space wild growing mushrooms, their whole caps contain a significantly higher amount of Po and Pb when compared to the stem, and their content in the whole cap was determined mainly by concentrations in the cap skin.
研究了大气沉降对不同环境下采集的野生蘑菇子实体中 Po 和 Pb 含量的影响。采集了形态不同的蘑菇物种的样本，即牛肝菌（Imleria badia (Fr.) Vizzini）、滑菇（Suillus luteus (L.) Roussel）、仙女环蘑菇（Marasmius oreades (Bolton) Fr.）和普通地星（Scleroderma citrinum Pers.），以及它们的菌丝体和土壤基质。将它们的子实体分为菌盖表皮、菌盖肉质部和菌柄。同时还采集了菌丝体和土壤基质。结果表明，仙女环蘑菇菌盖表皮中的 Po 和 Pb 活度浓度最高，分别为 3.20 ± 0.12 和 21.1 ± 0.5 Bq kg ww，分别占其总子实体质量的 31.2%和 78.7%。对于露天生长的野生蘑菇，其整个菌盖中 Po 和 Pb 的含量明显高于菌柄，其整个菌盖中的含量主要取决于菌盖表皮中的浓度。
