对采自内蒙古汞矿区的195份高等真菌标本及其基质进行了研究。Amiata和周围的锡耶纳（意大利中部），分析其总汞含量。木材分解者和许多种类的菌根真菌以非常低的速率积累金属;一些菌根种类和所有的腐殖分解者可积累高达100 μ g/g-1干重的汞，在污染最轻的地点，可积累高达底层63倍的汞。在矿化区，富集系数很少超过1。35种植物的甲基汞含量。（几乎全部可食用），范围在0.01和3.7 μ g/g-1干重之间。这些研究结果的可能意义和毒理学的影响，当地消费者被认为是。
Specimens (195) of higher fungi and their substrata collected in the Hg mining area of M. Amiata and around Siena (central Italy), were analyzed for their total Hg content. Wood decomposers and many species of mycorrhizal fungi accumulated the metal at a very low rate; some mycorrhizal species and all the humus decomposers may accumulate up to 100 .mu.g/g-1 dry weight of Hg and in the least contaminated sites, up to 63 times as much Hg as the substratum. In mineralized areas the concentration factor rarely exceeded 1. The methyl mercury content of 35 spp. (almost all edible), ranged between 0.01 and 3.7 .mu.g/g-1 dry weight. The possible significance of these findings and the toxicological implications for local consumers are considered.
