    Concentrations of trace elements in wild edible mushrooms
    (Elsevier Sci Ltd, 2001) Isiloglu, M; Yilmaz, F; Merdivan, M
    The concentrations of Cu, Cd, Co, Ni, Mn, Pb, Zn and Fe in 66 samples of mushroom fruiting bodies, representing seven species, mainly all edible, were determined by atomic absorption spectrophotometry. The mushrooms were collected from near roads and inner parts of forest and lawns in Bahkesir in the north western part of Turkey. The results indicate that the Fe level in the species Volvariella speciosa (Fr.) Sing. from near the road was the highest with a mean of 6990 mg/kg. The level of Ni was the highest in Clitocybe flaccida (Sow.: Fr.) Kummer, from near road with a mean of 3.32 mg/kg. Cu levels were almost similar for both areas within a range of 35-89 mg/kg in the different species. The Cd was accumulated mostly by Lactarius sanguifluus (Paulet: Fr.) Pr. and V. speciosa from near road with a mean of 1.60 mg/kg. Concentration of Mn, Pb, Co and Zn in L. sanguifluus from near road were the highest with means of 63.6, 7.66, 6.03 and 149 mg/kg, respectively. (C) 2001 Published by Elsevier Science Ltd.

    Heavy metal contents in some macrofungi collected in the northwestern part of Turkey
    (Springer-Verlag, 2001) Isiloglu, M; Merdivan, M; Yilmaz, F
    Eight metal contents were determined in wild growing macrofungi collected from two different areas in Balikesir and Akhisar (NW Turkey). The analysis has been done by atomic absorption spectrophotometry in 179 samples of 16 species. Pb was accumulated extensively by G. sessile and L. cinerascens in both areas. Concentration of Cd was significantly high in A, pseudopratensis from background area and M. excissa from near road area. The high concentrations of Fe and Zn were found in M, ramealis and L, cinerascens for both areas. The mean concentration of Cu was high in V. pratense from background area and C. butyracea var. butyracea from near road area. The highest mean concentrations of Co and Mn for both areas were seen in G. sessile and M. excissa, respectively. A high Ni concentration was found in G. sessile and H. hypothejus from background area. We found no considerably significant differences in the concentrations of all studied elements between two areas.
