This study investigated the Hg concentrations in Yellow-cracking Boletes Xerocomus subtomentosus mushrooms and beneath soils collected from the wild at twelve sites across Poland. This mushroom species has some potential to bioconcentrate Hg in the fruiting bodies, and the amount of Hg sequestered, depending on geographical location, can pose health risk to consumers. The values of Hg bioconcentration factor (BCF) varied for the sites between 0.80 ± 0.20 and 17 ± 12 in caps and 0.50 ± 0.10 and 7.9 ± 6.6 in stipes of fruiting bodies but decreased as soil Hg content increased from 72 ± 32 to 570 ± 130 ng/g dry weight. The specimens collected from minerals rich area of Złotoryja contained the highest Hg concentration, which reached 630 ± 400 in caps and 420 ± 260 ng/g dw in stipes, while the lowest observed Hg concentrations at the other sites were 72 ± 32 and 57 ± 13 ng/g, for cap and stipes respectively. Available literature data on Hg in Yellow-cracking Boletes was also up-dated.
本研究调查了波兰 12 个地点的野外采集的黄裂牛肝菌（Xerocomus subtomentosus）子实体及其下土壤中的汞浓度。该蘑菇物种在子实体中有一定的生物浓缩汞的潜力，根据地理位置的不同，被截留的汞含量可能对消费者构成健康风险。各地点子实体帽部汞生物浓缩系数（BCF）的变化范围为 0.80±0.20 至 17±12，柄部为 0.50±0.10 至 7.9±6.6，但随着土壤汞含量从 72±32 增加到 570±130ng/g 干重，BCF 值逐渐降低。从富含矿物质的 Złotoryja 地区采集的标本含有最高的汞浓度，帽部达到 630±400ng/g，柄部达到 420±260ng/g dw，而在其他地点观察到的最低汞浓度分别为帽部和柄部的 72±32ng/g 和 57±13ng/g。还更新了有关黄裂牛肝菌中汞的现有文献数据。
