In this study some heavy metal uptake in mushroom species, their metal content in soil substrate and the relation in between metal concentration in mushroom and soil were investigated. Mushroom species and soil in which mushroom species were grown were collected from Tokat region of Turkey. Six different mushroom species and their underlying soil (0-10 cm layer) samples were analyzed for some heavy metals (Cu, Pb, Fe, Zn, Cd, Mn, Ni, Cr and Co). The analysis was performed with an atomic absorption spectrometer. The results indicate that in general, heavy metal contents in all mushroom species were lower than the underlying soil substrates except for some mushroom species. The results obtained from the analyses of mushroom and underlying soil samples were evaluated using linear correlation analysis and concentration factors to identify the metal accumulation of mushrooms.

Six trace metals (Fe, Cu, Mn, Zn, Pb, Cd) were determined in 12 different mushroom samples collected from polluted and unpolluted locations in Tokat, Turkey using flame and graphite furnace atomic absorption spectrometry after dry ashing, wet ashing and microwave digestion. The study of sample preparation procedures showed that the microwave digestion method was the best. The proposed method showed satisfactory recovery, detection limits and standard deviation for trace metals determination in mushroom samples. The results were in the ppm range 184-7560 (Fe), 12-181 (Cu), 16-122 (Mn), 18-403 (Zn), 0.75-7.77 (Pb), and 0.14-5.50 (Cd). [ABSTRACT FROM AUTHOR]
