摘要

Fungi can effectively accumulate various metallic elements, metalloids and non-metals in fruiting bodies. This study provides information on the accumulation of Ag, As, Ba, Cd, Co, Cs, Cu, Cr, Li, Mn, Ni, Pb, Rb, Sr, V, Tl, U and Zn in the edible mushroom Sarcodon imbricatus (L.) P. Karst. using the technique of inductively coupled plasma - mass spectrometry with a dynamic reaction cell mode. Mushrooms were foraged from four regions in Poland. Baseline concentrations of minerals, expressed in mg kg~(-1) dry biomass (db), were in the composite samples of caps in the range: for Ag (0.27-0.29), As (1.0-1.9), Ba (0.31 0.45), Cd (4.5 6.3), Co (0.23-1.9), Cu (28 35), Cr (0.19 0.29), Cs (20-38), Li (0.013-0.020), Mn (5.9-8.8), Ni (0.81-1.4), Pb (0.94-1.6), Rb (490 700), Sr (0.14-0.19), Tl (0.058-0.11), U (0.002-0.002), V (0.044-0.054) and Zn (140-160). Concentration levels of Ag, As, Cd, Cs, Pb and Zn were higher in caps than in stipes of S. imbricatus, whereas for other elements the distribution between caps and stipes was nearly equal or for some differed depending on the location. Certainly, the content of toxic Cd in S. imbricatus was elevated (0.45-0.63 mg kg~(-1) in fresh caps) and therefore eating this mushroom could increase exposure to Cd. In addition, the content of toxic As in S. imbricatus was elevated.

Karst。使用感应耦合等离子体质谱技术与动态反应池模式。蘑菇来自波兰的四个地区。盖的复合样品中矿物质的基线浓度以mg kg〜（-1）干生物量（db）表示，范围为：Ag（0.27-0.29），As（1.0-1.9），Ba（0.31 0.45） ），Cd（4.5 6.3），Co（0.23-1.9），Cu（28 35），Cr（0.19 0.29），Cs（20-38），Li（0.013-0.020），Mn（5.9-8.8），Ni（ 0.81-1.4），Pb（0.94-1.6），Rb（490700），Sr（0.14-0.19），Tl（0.058-0.11），U（0.002-0.002），V（0.044-0.054）和Zn（140- 160）。帽中的银，砷，镉，铯，铅，锌和铅的浓度均高于钝性链球菌的柄，而对于其他元素，帽和柄之间的分布几乎相等或因位置而异。当然，弯曲链球菌中有毒的镉含量有所增加（新鲜瓶盖中为0.45-0.63 mg kg〜（-1）），因此食用这种蘑菇可增加对镉的暴露。另外，提高了链球菌中有毒As的含量。
