本文报道了产于中国西南部环太平洋汞带云南及欧洲汞带以外地区的几种真菌属Xerocomus子实体中总汞（THg）的积累、分布、污染和可能的膳食摄入量的研究结果。蘑菇X。puniceus（Boletus amygdalinus）、X. spadiceus（Boletus ferrugineus）和X. versicolor（X. rubellus），X. badius（Boletusbadius）来自欧洲白俄罗斯和X. badius，X. chrysenteron，黄背角X. ferrugineus、刺萼木X. versicolor（X. rubellus）和X.来自波兰的subtomentosus。采用冷原子吸收光谱法测定了真菌和土壤样品中的THg。估计也可能的膳食摄入量和健康风险的THG在Xerocomus属。经消费者检验。结果表明，在不同的温度条件下，Xerocomus spp.出现在欧洲本地化在波兰和白俄罗斯是在一个数量级低于从云南省的样品中确定的水平。云南蘑菇THg含量升高的原因可能与土壤地球化学背景中Hg的富集有关。评估的剂量表明，300 g X.来自中国云南武定地区的spadiceus如果每周食用一次，将以接近为THg设定的暂定每周耐受摄入量（PTWI）值的剂量提供THg，而云南和欧洲所有其他地区的剂量将更低。在云南武定地区，X.每周超过300 g新鲜子实体的spadiceus将以超过PTWI值的剂量提供THg。
This article presents the results of the study on accumulation, distribution, contamination and probable dietary intake of total mercury (THg) in fruiting bodies of several species of Fungi genus Xerocomus, which emerged in the circum-Pacific mercuriferous belt region in southwestern China in Yunnan and beyond of the mercuriferous belts in the region of Europe. The mushrooms X. puniceus (Boletus amygdalinus), X. spadiceus (Boletus ferrugineus) and X. versicolor (X. rubellus) were from the Yunnan land, and X. badius (Boletus badius) was from the region of Europe in Belarus and X. badius, X. chrysenteron, X. ferrugineus, X. versicolor (X. rubellus) and X. subtomentosus from Poland. The THg in the fungal and soil materials was determined using validated method by cold-vapour atomic absorption spectroscopy. Estimated was also probable dietary intake and health risk from THg in Xerocomus spp. examined by consumers. The data showed that THg content of Xerocomus spp. emerged in the European localizations in Poland and Belarus is at an order of magnitude lower level than determined in samples from the Yunnan Province. A reason for an elevated content of THg in mushrooms from Yunnan can be related to abundance of Hg in the geochemical background of soils there. The assessed doses showed that a single meal composed of 300 g of fresh fruiting bodies of X. spadiceus from the Wuding localization in Yunnan in China if consumed once a week will provide THg at dose close to the provisional tolerable weekly intake (PTWI) value set for THg, while doses will be lower for all other localizations in Yunnan and Europe. In the Wuding localization in Yunnan a frequent consumption of X. spadiceus in volume exceeding 300 g of fresh fruiting bodies per week will provide THg at a dose exceeding the value of PTWI.
