Fruiting bodies of ten mushroom species (edible and non-edible) were analysed for their heavy metals content. Results indicated that the concentration of heavy metals accumulated by the mushrooms were species-dependent. Formes applanatus had the highest concentration of Zn and Cu, while the levels of Pb and Cd were highest in the non-edible species of Paragyrodon sphaerosporus. Iron was highly accumulated by Polyporus frondosis with a maximum value of 731.6±13.2 mg/kg DM. The heavy metal accumulating potential of the mushrooms generally decreased in the trend: Fe > Zn > Cu > Mn > Pb > Cd. However, the levels in all the edible species (Polyporus frondosis, Armillariella mellea, Pleurotus sapidus, Polyporus sulphureus, Pleurotus ostreatus) did not exceed the stipulated FAO/WHO (1976) dietary standards.
