In this study, Mycoremediation technique was used to analyse the potential of mushroom in absorbing heavy metals from contaminated soil. A small village Sitagarha located in Hazaribag, Jharkhand was selected as sampling site. Soil sample was collected from two different sites – from field where cow manure was used as fertilizer and the other soil sample where chemical fertilizer was mixed. A control sample was also collected from nearby barren land where no cultivation was carried out since decades. After initial screening, three heavy metals Cu, Cd and Zn were selected to carry out further studies. The soil sample was processed in laboratory and analysed in AAS to detect the concentration of heavy metals. Results showed the presence of heavy metals as – Cd > Cu > Zn. Further these soil samples were mixed along with straw and spawn to prepare a mushroom cultivation bag as mushroom has the property to absorb heavy metals. The result of absorbance of heavy metals by mushroom was somewhere an indication that mycoremediation proofs to be an important tool to fight against heavy metals.
