Evaluation of trace metal contents of some wild edible mushrooms from Black sea region, Turkey.
Fructification organs of Calvatia excipuliformis, Lycoperdon perlatum, Laccaria amethystea, Armillaria mellea, Marasmius oreades, Xerula radicata, Cantharellus cibarius, Craterellus cornucopioides, Cantharellus tubaeformis, Hypholoma fasciculare, Clitocybe gibba, Collybia dryophila, Lepista nuda and Mycena aetites were collected from different localities in Black sea region of Turkey. Their trace metals concentrations were determined by atomic absorption spectrometry after wet and microwave digestion. The results were (as mg/kg) 150-1741 for iron, 15.5-73.8 for copper, 28.6-145 for manganese, 43.5-205 for zinc, 4.8-42.7 for aluminium and 0.9-2.6 for lead. The levels of lead analyzed in some edible mushroom samples were found to be higher than legal limits. The relative standard deviations (R.S.D.) were found below 10%. The accuracy of procedure was confirmed by certified reference material.
