Studies Concerning Heavy Metals Bioaccumulation of Wild Edible Mushrooms from Industrial Area by Using Spectrometric Techniques

摘要

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.
