Cadmium, lead and zinc contents of sporocarps of some basidiomycetous fungi within gharbia governorate, Egypt.

Abstract

Zinc, cadmium and lead concentrations were determined in sporocarps of Ganoderma applanatum (Pers.ex Wallr.), Ganoderma lucidum (Leys.) Fr., Heteroporus biennis (Bull.exFr.), Lycoperdon molle (Pers.: Pers), Lycoperdon pyriforme (Schaeff.ex Pers.), Peniophora incarnata (Fr.) Karst.syn, Pisolithus tinctorius (Mich.ex Prs) Coker & Couch, Pleurotus foliicola (Pat. & Lagarde), Polyporus hispidus (Bull.: Fr.) Fr.) and Scleroderma citrinum (Pers) collected from Gharbia governorate, Egypt during (2003-2004). The highest concentration of zinc and cadmium was recorded from Polyporus hispidus basidiocarp, which gave 98±8.0 and 0.54±0.04 mg/kg dry wt, respectively. However, Peniophora sp.incarnata fruiting bodies contained 48±4.04 mg/kg dry wt of lead. Determination of zinc, cadmium and lead is very important from the economic value of these fungi when used for human or animal feed and/or plants as biofertilizers.
