Abstract
Two heavy metals (nickel and cadmium ) in 15 specis of wild mushrooms were determined using flame atomic adsorption spectrometry (VARIAN, SpectrAA-220Fs). The mushrooms were collected from Miyi, China. The study explored the accumulation of heavy metals in different macrofung. It is found that the range of Nickel and Cadmium in mushrooms were 1.78-21.22 mg/kg and 0.47-21.84 mg/kg. Minimal and maximal concentrations of heavy metals were determined in Lentinus edodes and Boletus edulis for nickel, Russula alutacea and Russula delica for cadmium,respectively. The order of the levels of heavy metals in the mushrooms samples was found to be as Ni>Cd. Cadmium values in wild mushrooms collected from Miyi were generally higher than the previous studies. Nickel contents were in agreement with the literature value.
