This study examined the mercury concentration in the Grisette Amanita vaginata Fr. and soil below the fruiting bodies collected between 2000 and 2008 from the wild at seven distant sites across Poland. The Hg content in samples was determined by cold atomic absorption method (CV-AAS) at a wavelength of 253.7 nm. Mean Hg contents varied from 0.096 ± 0.052 to 0.48 ± 0.13 mg kg(-1) dry matter (dm) in caps (range, 0.043-0.73 mg kg(-1)), from 0.047 ± 0.02 to 0.23 ± 0.07 mg kg(-1) dm (range, 0.028-0.47 mg kg(-1)) in stipes, and in underlying soil were from 0.035 ± 0.018 to 0.096 ± 0.036 mg kg(-1) dm (range, 0.017 to 0.16 mg kg(-1)). The median Qc/s values ranged from 1.2 to 2.2 (mean 1.2 ± 0.4 to 2.1 ± 0.5) indicating that Hg content in stipes was generally lower than in caps. This mushroom species has some potential to bioconcentrate Hg in the fruiting bodies, as the values of the bioconcentration factor (BCF) varied for the sites between 1.2 ± 0.6 to 11 ± 5 for caps and 0.61 ± 0.26 to 7.4 ± 3.9 for stipes. Also available literature data on Hg in A. vaginata are reviewed and discussed.
本研究检测了 2000 年至 2008 年期间在波兰七个不同地点采集的野生灰花纹鹅膏菌 Fr. 子实体及其下土壤中的汞浓度。采用冷原子吸收法（CV-AAS）在 253.7nm 波长下测定样品中的 Hg 含量。子实体中 Hg 含量的平均值在菌盖中为 0.096±0.052 至 0.48±0.13mg/kg 干重（dm）（范围为 0.043-0.73mg/kg），在菌柄中为 0.047±0.02 至 0.23±0.07mg/kg dm（范围为 0.028-0.47mg/kg），而在其下土壤中的含量为 0.035±0.018 至 0.096±0.036mg/kg dm（范围为 0.017 至 0.16mg/kg）。中位数 Qc/s 值在 1.2 至 2.2 之间（平均值为 1.2±0.4 至 2.1±0.5），表明菌柄中的 Hg 含量通常低于菌盖。这种蘑菇品种有一定的生物浓缩 Hg 的潜力，因为生物浓缩因子（BCF）的值因地点而异，菌盖为 1.2±0.6 至 11±5，菌柄为 0.61±0.26 至 7.4±3.9。还对有关灰花纹鹅膏菌中 Hg 的现有文献数据进行了综述和讨论。
