Determination and evaluation of Cu, Mn, Zn, Cd, Pb and Ni contents in wild-grown edible mushroom species from Cappadocia, Turkey
Abstract
The aim of this study was to determine the Cu, Mn, Zn, Cd, Pb and Ni concentrations in sixteen different wild-grown edible mushroom species grown in Niğde and Nevşehir. In the sample preparation step, the samples were dried, ground and sieved by 200 meshed sieve, consecutively. The extractions of metals were conducted by acid mineralization using concentrated nitric acid and hydrogen peroxide in microwave digestion unit. The determinations of metals were performed by flame atomic absorption spectrometry. Among the mushroom samples that were analyzed, Cu, Mn, Zn, Cd, Pb, and Ni concentrations were determined in the range of 6.7-1353, 4.7-109, 44.8-406, 0.14-6.4, 4.28-25.6 and 1.7-11.0 mg/kg, respectively. The accuracy and precision of the proposed method for metal determinations were validated by using the NIST SRM 1573a Tomato Leaves certified standard material. The obtained results were evaluated in terms of human health and compared with each other and previously reported values in the literature. In addition, the habitats of the mushroom samples were identified.
