Study of heavy metals in some cultivated and uncultivated mushrooms of Turkish origin

Twenty-four different species of uncultivated mushrooms of Turkish origin and one cultivated mushroom (Agaricus bisporus) growing in soil composts with 16 different compositions were analysed spectrometrically for their heavy metal (Pb, Cd, Hg, Fe, Cu, Mn, and Zn) contents. The highest Pb levels were 2.35 mg kg(-1) for the species Agaricus bitorquis and 7.00 mg kg(-1) for the species of Hypholoma fasciculare growing in the vicinity of the road. The highest Cd level was 3.42 mg kg(-1) for the species of Hydnum repandum. In the wild mushrooms the highest Fe content was 93.6 mg kg(-1) for the species of Bovista plumbea and the highest Cu content was 51.0 mg kg(-1) for the species Tricholoma terreum. The highest Mn content was 35.9 mg kg(-1) for the species Laccaria laccata and the highest Zn content was 31.6 mg kg(-1) for the species of Agaricus bitorquis. (C) 1998 Elsevier Science Ltd.
