摘要

The aim of this study was to determine profile of 19 elements of caps and stipes of Hazel Bolete (Leccinum griseum) and soil substratum collected at the area of the Commune of Go?dap, within Go?dap County in the Warmian-Masurian Voivodeship in Poland compared to the Cd, Pb and Hg levels with current hygienic standards. The elements were determined using validated methods, that is, inductively coupled plasma atomic emission spectroscopy (ICP-AES) and cold vapour atomic absorption spectrometry (CV-AAS). K and Mg were particularly abundant, mean values were 41 and 1.2 mg/g dry weight (dw) in caps of Hazel Bolete, respectively, and they were followed by Na, Rb, Zn and Ca at 560, 350, 210, 110 μg/g dw, respectively. Concentrations of Fe, Cu, Al and Mn were ~ 20 to 50 μg/g dw, while concentrations of other elements were ~ l.0 μg/g dw or less. Pb and Cd content of Hazel Bolete from pristine area did not exceed the maximum levels set by European Union for cultivated mushrooms. In the case of Hg and area surveyed, eating Hazel Bolete did not result in exceeding provisional tolerable weekly intake (PTWI) value.
