Oznaczono stężenia metali (Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, Pb, Rb, Sr i Zn) oraz fosforu w owocnikach koźlarza babki zebranych w okolicach Starachowic w woj. świętokrzyskim. Pierwiastki oznaczono za pomocą metody ICP-AES i CV-AAS. W owocnikach zdecydowanie dominował potas, fosfor i magnez, a pierwiastki takie, jak kobalt i chrom występowały w najmniejszej ilości. Dla niektórych pierwiastków stwierdzono wyraźne zróżnicowaną zawartość w zależności od części morfologicznej owocnika. Kapelusze koźlarza babki cechowała względnie duża zawartość kadmu.
The concentration of 20 elements: Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Rb, Sr and Zn were determined in the fruiting bodies of wild grown brown birch bolete (Leccinum scabrum) collected in the vicinity of the town Starachowice in 2001. Dried and pulverized mushrooms (separately caps and stalks) were wet digested with concentrated nitric acid under pressure in closed vessels in a microwave oven. The analysis was performed by optical emission spectrometry with inductively coupled plasma and cold-vapour atomic absorption spectroscopy. The analytical methods used were truly validated and controlled. The caps and stalks of brown birch bolete were relatively abundant in potassium: 34 ± 5 and 21 ± 4; phosphorous: 6.2 ± 1.0 and 2.4 ± 0.7; and magnesium: 0.97 ± 0.12 and 0.51 ± 0.07 mg/g d.m., respectively. Concentrations of Ag, Cd, Cr, Cu, Fe, Hg, K, Mg, P, Pb, Rb and Zn were higher in the caps than in the stalks. Cadmium content of the caps on the average exceeded the 0.2 mg/kg limit specified for cultivated species.
