Abstract

Heavy metals accumulation in soil poses a threat to surface water and groundwater. Phytoremediation which involves the use of plants to remediate contaminated soil or water has a potential cleanup technology for the removal of heavy metals. Melastoma malabathricum L., which is the local herb plant locally known as 'Senduduk' was used to investigate the maximum uptake of lead (Pb) from contaminated soil. The soil cultivation of plant will be exposed to Pb concentration 20, 100, 200 mg/kg respectively in 70 days of retention time. The analysis from ICP-MS indicates that the highest accumulated of Pb in the roots was 145,375 mg/kg or 26.6 mg ofPb, in term of total mass, with exposed concentration 200 mg/kg. The accumulation ofPb in stem and leaf did not differ significantly, with maximum value in stem was 2632 mg/kg or 0.7 mg of Pb while in leaf was 1073 mg/kg or 0.6 mg of Pb. The Pb distribution order in part of Melastoma malabathricum L. was: root > stem > leaf that indicates that the translocation of Pb from root to overground part is not very effective. However, the high uptake capacity in root shows this plant is a good bioaccumulator for heavy metals like Pb.
