Phytoremediation of Lead Contaminated Land Using Vetiver zizanoides and Citric Acid as Chelating Agent

Environmental pollution due to hazardous waste in Karangdawa, Margasari, Tegal has an impact on soil and groundwater quality. Lead found the exceeds permissible standards. It is necessary recover from because it can enter food crops accumulate human body. Phytoremediation commonly used land remediation it’s economical doesn’t cause secondary environmental problems. One of ways optimize by using chelating agents. The purpose study was analyze ability Vetiver zizanoides most optimum dose variation Citric acid uptake plant. as metal chelators Pb investigated for 28 days with doses 0.5 g/kg, 1 2 g/kg. Analysis concentration roots, stems, AAS. From results study, able survive exposure up 4979.8 ppm. Application g/kg soil, increased bioconcentration, bioaccumulation compared control plants. indicated that addition a agent could increase function phytoremediation agent.
