Określono zawartość Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Sr, Rb i Zn w reprezentatywnej partii owocników (osobno kapeluszy i trzonów) czubajki kani oraz w wierzchniej warstwie (0 – 10 cm) gleby spod owocników z terenu Chodelskiego Parku Krajobrazowego w woj. lubelskim. Owocniki czubajki kani są względnie bogate w K, P, Zn, Cu, Fe, Al i Mn, silnie nagromadzają z podłoża Ag, Rb, Cu, Zn i Hg (BCF > 1), a wykluczają Fe, Al, Pb, Cd (trzony), Ba, Sr, Ni i Co (BCF < 1).
Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Sr, Rb and Zn have been quantified in the caps and stalks of Parasol Mushroom and underlying soil substrate collected at the Chodelski Landscape Parc in Lubelskie Voievodeship in 2002. The edible caps of Parasol Mushroom, when compared to the inedible stalks, on the average contained higher quantities of K, P, Mg, Zn, Cu, Rb, Ag, Pb, Hg, Cd and Cr, and lower quantities of Ca, Mn, Na, Ba, Sr, Fe, Al, Ni and Co. The caps of Parasol Mushroom were relatively rich in potassium (49 ± 3 g/kg d.m.), phosphorous (28 ± 1 g/kg d.m.) and magnesium 2.5 ± 0.1 g/kg d.m.), but also in zinc (650 ± 36 mg/kg d.m.), copper (220 ± 33 mg/kg d.m.) or silver (16 ± 8 mg/g d.m.). As to elements classified as toxic, the caps of Parasol Mushroom were relatively abundant in lead (5.9 ± 1.7 mg/kg d.m.), and less in mercury (3.1 ± 0.9 mg/kg d.m.), cadmium (1.9 ± 1.0 mg/kg d.m.) and barium (1.3 ± 0.4 mg/kg d.m.). The elements that easily accumulate (BCF > 1) in the caps of Parasol Mushroom include silver (BCF 730 ± 630), potassium (BCF 480 ± 170), phosphorous (230 ± 42), copper (BCF 125 ± 18) and rubidium (BCF 100 ± 48), but also zinc (BCF 59 ± 6), magnesium (BCF 30 ± 7) and cadmium (BCF 11 ± 6), and, to a smaller extent, sodium (BCF 2.0 ± 1.2) and chromium (BCF 1.8 ± 0.4). The elements excluded (BCF < 1) from the fruiting bodies of the Parasol Mushroom were iron, aluminum, lead, barium, strontium, nickel and cobalt, while calcium and manganese were excluded only from the caps.
