The contamination, bio-concentration and distribution of mercury (Hg) in wild mushrooms of the genus Tricholoma such as T. equestre, T. portentosum, T. columbeta, and T. terreum were studied, and the possible dietary intake and risk for human consumers in Europe was estimated. Mushrooms, together with the associated forest topsoils were collected from 10 unpolluted and geographically distant areas, far from local or regional emission sources, in Poland (2 sites) and Croatia (8 sites). The Hg contents were in the range 0.10 ± 0.06 to 0.71 ± 0.34 mg kg-1 dry matter in caps and 0.04 ± 0.02 to 0.38 ± 0.13 mg kg-1 in stems. The corresponding topsoil concentrations varied over a relatively narrow range between sites, from 0.013 ± 0.003 to 0.028 ± 0.006 mg kg-1 dry matter. Overall, the study results showed low levels of mercury both, in edible Tricholoma mushrooms and forest topsoils from background (unpolluted) forested areas in Croatia and Poland. The morphological distribution showed considerably greater concentrations of mercury in the caps relative to the stems with ratios ranging from 1.6 ± 0.6 to 3.9 ± 1.8. T. equestre showed good ability to bioconcentrate Hg, with bioconcentration factors (BCF) values in the range 18 ± 7 to 37 ± 18. The data suggests that Tricholoma mushrooms from unpolluted areas in southern and northern regions of Europe can be considered as a low risk food from the point of view of the tolerable Hg intake.

口蘑属植物中汞的污染，生物富集和分布。来自欧洲南部和北部地区的蘑菇。

研究了口蘑属的野生蘑菇中的汞（Hg）的污染，生物富集度和分布，例如马齿T，Portentosum，Columbeta和T. terreum，以及可能的饮食摄入量和对人类的危害估计欧洲的消费者。从波兰（2个地点）和克罗地亚（8个地点）的10个无污染且地理上较远的地区（远离本地或区域排放源）收集了蘑菇以及相关的森林表层土。瓶盖中的汞含量为0.10±0.06至0.71±0.34 mg kg-1干物质，茎中为0.04±0.02至0.38±0.13 mg kg-1。站点之间相应的表土浓度在相对狭窄的范围内变化，从0.013±0.003到0.028±0.006 mg kg-1干物质。总体而言，研究结果表明汞含量都很低，来自克罗地亚和波兰背景（未受污染）森林地区的食用松茸蘑菇和森林表土。形态分布表明，相对于茎，帽中的汞浓度明显更高，比率范围为1.6±0.6至3.9±1.8。T. equestre具有很好的生物富集汞的能力，生物富集因子（BCF）值在18±7至37±18范围内。数据表明，欧洲南部和北部未受污染地区的口蘑蘑菇可认为是较低的从可忍受的汞摄入量的角度考虑食物风险。6±0.6至3.9±1.8。T. equestre具有很好的生物富集汞的能力，生物富集因子（BCF）值在18±7至37±18范围内。数据表明，欧洲南部和北部未受污染地区的口蘑蘑菇可认为是较低的从可忍受的汞摄入量的角度考虑食物风险。6±0.6至3.9±1.8。T. equestre具有很好的生物富集汞的能力，生物富集因子（BCF）值在18±7至37±18范围内。数据表明，欧洲南部和北部未受污染地区的口蘑蘑菇可被认为是低水平的蘑菇。从可忍受的汞摄入量的角度考虑食物风险。
