Determination of heavy metals content in wild mushrooms and soil by EDXRF and FAAS techniques

چکیده
The heavy metals (Cd, Cr, Ni, Pb, Zn, Cu, Fe, Mn) content of some edible wild mushrooms (Amanita caesarea, Amanita rubescens, Amanita vaginata, Amanita spissa) and soil samples, of ten sites from Dambovita county Romania, were analyzed. Elements concentrations were determined by Flame Atomic Absorption (FAA) spectrometry and Energy Dispersive X-ray spectrometry (EDXRF) in 40 samples of Amanita species and 40 underlying soil samples. In fruiting body of these mushrooms, the highest mean concentration of macroelements (dry mass basis) was found for Zn and Fe. Some metals (Cd, Pb, Cr and Zn) were bioconcentrated mainly in cap than the stipe of fruiting body. The mean concentration of heavy metals (Cd, Cr, Ni, Pb) was higher in mushrooms which was collected on sites near urban settlements Lead was determined at highest concentration in soil surrounding Amanita vaginata. The studied mushrooms were good bioaccumulators of zinc and cupper. The iso-concentration curves of heavy metals in samples of Amanita sp. and soil were realized with Surfer 9 Model.

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 Dispers...
متن کاملThe Mycoremediation of Metals Polluted Soils Using Wild Growing Species of Mushrooms
Many of mushrooms species from the forest area of Bucegi Mountains are consumed by the native population without thinking about the heavy metals uptake in the human body. From all the edible species we choose eight mushrooms, part of them considered edible and part with uncertain edibility. Heavy metals concentration in the fruiting body of mushrooms are different from one species to another an...
متن کاملHeavy Metal Concentrations in Soils and Irrigation Waters in Thessaly Region, Central Greece
The purpose of this work was to provide information on heavy metals concentration in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate high levels of heavy metals, especially Cadmium. During the years 1998, 1999 and 2000, 795 surface soil samples (0-30 cm depth) and 200 water samples were collected from Kardit...
