测定了4种野生食用菌子实体及其基质中重金属的含量。采用能量色散x射线荧光法（EDXRF）结合火焰原子吸收法（FAAS）测定野生食用菌及其基质中Cr、Mn、Fe、Ni、Cu、Zn、Se和Cd的浓度。通过积累系数K-a的计算，定量评价了蘑菇从基质中吸收元素的关系。在金属冶炼厂附近生长的蘑菇中观察到锌的高积累（K-a范围为1.01至2.01）。
The aim of this work was to determine the heavy metal content of the fruiting bodies of four species of wild edible mushrooms and their respective substrates. The samples were collected from Dambovita County, Romania, at various distances from of a metal smelter, to asses the concentration of Cr, Mn, Fe, Ni, Cu, Zn, Se and Cd in the wild edible mushrooms and their substrate using Energy Dispersive X-ray Fluorescence (EDXRF) spectrometry together with Flame Atomic Absorption (FAAS) spectrometry. A quantitative evaluation of the relationship of element uptake by mushrooms from substrate was made by calculating the coefficient accumulation (K-a). A high accumulation of Zn (K-a range 1.01 to 2.01) was observed in mushrooms growing in the vicinity of the metal smelter.
