Four heavy metals viz: lead, zinc, manganese and copper were used to artificially contaminate the soil in the form of lead nitrate, zinc sulphate, manganese sulphate and copper sulphate at concentration of 0.05mol/kg of soil while uncontaminated soil serves as control. Pleurotus tuber-regium was grown on the heavy metal contaminated and uncontaminated soil to maturity in a period of 30 days. The heavy metals was determined using atomic absorption spectrophotometer on the soil before contamination with heavy metals, after contamination with heavy metals and in the mushroom sample before cultivation on soil and the matured mushroom fruiting body cultivated on the heavy metal contaminated soil. The experiment revealed the effect of each of the heavy metals on the pileus development of the mushroom. Moreover, it was observed that Pleurotus tuber-regium is efficient in absorbing heavy metals as the levels of remaining heavy metals in the contaminated soil are below the limit of detection (<0.01mg/100g) and having high bioconcentration factor for all the metals.
