摘要

Leccinum scabrum is an edible mushroom common in European regions in the northern hemisphere. Macro and trace mineral constituents such as Ag, Al, Ba, Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, P, Rb, Sr and Zn were studied in L. scabrum and in the top soil collected from the same location underneath soil substratum. The pseudo-total and labile (extractable fraction of minerals) were measured to get insight into the levels, distribution between the morphological parts of fruiting bodies, potential for their bioconcentration by mushroom and evaluated for human exposure via consumption of the mushroom. The sampling sites include the Darlubska Wilderness, Trojmiejski Landscape Park, Sobieszewo Island, Wdzydze Landscape Park and outskirts of the Ktrzyn town in Mazury from the norther part of Poland. Median values of K, Rb and P concentrations in dehydrated L. scabrum were for caps in range 27,000-44,000mg kg(-1), 90-320mg kg(-1) and 6,200-9,100mg kg(-1), and followed by Mg at 880-1,000mg kg(-1,) Ca at 48-210mg kg(-1) and Al at 15-120mg kg(-1). The median concentrations of Cu, Fe, Mn and Zn in caps were in range 15-27mg kg(-1) db 38-140mg kg(-1), 5.3-27mg kg(-1) and 130-270mg kg(-1). For Ba and Sr, concentrations on the average were at approximate to 1mg kg(-1), and almost equally distributed between the caps and stipes of the fruiting bodies. L. scabrum mushrooms were low in toxic Ag, Cd, Hg and Pb, for which the median values in dried caps from five locations were, respectively, in range 0.48-0.98mg kg(-1) (cap to stipe index, Q(C/S), was 2.5-4.1), 1.0-5.8mg kg(-1) (Q(C/S) 2.9-3.8), 0.36-0.59mg kg(-1) (Q(C/S) 1.6-2.7) and 0.20-0.91mg kg(-1) (Q(C/S) 1.2-1.9). Substantial variations in the concentrations of the pseudo-total fraction (extracted by aqua regia) or labile fraction (extracted by 20% solution of nitric acid) of the elements determined in forest topsoils were noted between some of the locations examined. The elements K, P, Cd, Cu, Hg, Mn, Na, Rb and Zn can be considered as those which were bioconcentrated by L. scabrum in fruiting bodies, while the rates of accumulation varied with the sampling location.
