REMEDIASI TANAH TERCEMAR TIMBAL (Pb) DAN AKUMULASINYA PADA TANAMAN GUMITIR (Tagetes erecta L.)

Lead (Pb) is a common pollutant found in agricultural soils and often contaminates the plants growing on soil. One way to reduce content of heavy metal contamination such as Pb soil through phytoremediation. The purpose this study was soils. method used remediation by planting gumitir (Tagetes erecta L.) added with various concentrations Pb2+. results showed that before gumitir, A, B, C 100; 200; 400 mg Pb/kg soil, respectively, having concentration 108,97±2,25; 214,18±5,47; 447,04±4.89 mg/kg, while harvesting time 100,52±1,66; 170,04±2,88; 397,98±2,24 respectively. part plant absorbed highest root, which 47,01±4,52 mg/kg. effectiveness absorption were <50% TF BCF values ??< 1, so mechanism accumulating lead less effective or called phytostabilization.
