MINOR ELEMENT AND HEAVY METAL CONTENT OF EDIBLE WILD MUSHROOMS NATIVE TO BOLU, NORTH-WEST TURKEY

摘要

The minor element (Ca, Cu, Fe, K, Mg, Mn, Na, P, Zn) and heavy metal (Cd, Cr, Ni, Pb) contents of eight edible wild mushrooms (Amanita ovoidea, Boletus edulis, Clito-cybe geotropa, Hydnum repandum, Lactarius musteus, Macrolepiota procera, Melanoleuca brevipes, Melano-leuca subalpina), from the Province of Bolu in North-West Turkey, were analysed. Marked differences were noted in mineral composition between these mushroom species. The results showed that some of them have significant levels of minerals, thus providing a good alternative source of nutrition for those requiring specialised diets. Levels of heavy metals were found to be within safe limits. The data were analysed statistically by Pearson's two-tailed correlation analysis and statistically significant relationships were observed. Mineral contents were determined using a Varian Vista Model ICP-AES apparatus.
