Mushroom Cortinarius caperatus is one of the several edible wild-grown species that are widely collected by fanciers. For specimens collected from 20 spatially and distantly distributed sites in Poland the median values of Hg contents of caps ranged from 0.81 to 2.4mgkg(-1) dry matter and in stipes they were 2.5-fold lower. C. caperatus efficiently accumulates Hg and the median values of the bioconcentration factor for caps range from 120 to 18 and for stipes from 47 to 7.3. This mushroom even when collected at background (uncontaminated) forested areas could be a source of elevated intake of Hg. The irregular consumption of the caps or whole fruiting bodies is not considered to pose a risk. Frequent eating of C. caperatus during the fruiting season by fanciers should be avoided because of possible health risk from Hg. Available data on Hg contents of C. caperatus from several places in Europe are also summarized.
蘑菇卷边桩菇是几种可食用的野生品种之一，受到爱好者的广泛采集。对于从波兰20个空间分布较远的地点采集的标本，菌盖汞含量的中位数范围为0.81至2.4毫克/千克干物质，菌柄中的汞含量则低2.5倍。卷边桩菇能有效积累汞，菌盖生物富集系数的中位数范围为120至18，菌柄为47至7.3。这种蘑菇即使在背景（未受污染）林区采集，也可能是汞摄入量增加的一个来源。不规则食用菌盖或整个子实体不被认为有风险。由于汞可能带来健康风险，应避免爱好者在出菇季节频繁食用卷边桩菇。还总结了欧洲几个地方卷边桩菇汞含量的现有数据。
