Small scale gold mining provides an important source of income for miners in rural communities where economic alternatives are extremely limited. However, it releases mercury which damages the environment and poses risks to those in the nearby community. Phytoremediation is considered as a simple and cost-effective method for the cleanup of heavy metal from contaminated soil. Phytoremediation is a technology that uses plants to degrade, extract, contain or immobilize contaminants from soil and water. In particular, phytoextraction is the uptake of contaminants by plant roots and translocation within the plants to shoots or leaves. Contaminants are then removed by harvesting the plants. The objective of this research is to examine the ability of sweet sorghum and its inoculation using chromium uptake enhancing rhizobacteria for phytoremediation of gold mine tailing. Two varieties of sweet sorghum were used in this experiment, i.e. FS501, and KCS105. The seed of the sweet sorghum was sown in mercury containing tailing or a mixture of it with uncontaminated soil. Plant biomass and its mercury content were determined 35 days after sowing. Only FS501 was able to grow on tailing containing 26.94 ppm of mercury. Inoculation of the sweet sorghum with the rhizobacteria does not affect its biomass but increase its mercury uptake significantly. Mixing the tailing material with uncontaminated soil causes an increase in biomass but reduce the mercury content in plant significantly. As a result, the amounts of removable mercury decrease significantly. Inoculation with the rhizobacteria has no effect on mixed material. |
