Abstract
This study aims to measure and characterize metal accumulation in Acacia organs were carried out, as well as to reveal their relation to the physical, chemical, and metallic properties in the soil from the revegetation land of the Bangka Island tin mining. This research was conducted on three different lands, namely: forest, tin mining revegetation land > 5 years, and tin mine revegetation land < 5 years. Samples were taken in the form of rhizosphere soil and roots, stems and leaves of Acacia. The soil attached to the roots of Acacia was taken slowly, then the physical and chemical properties of the soil were analyzed. Some metals were measured both in the soil and in Acacia organs, such as: Pb, Cd, Co, Cr, Ni, Mo, Ag, Sn, Fe, Mn, Cu, Zn, Al. Data were analyzed by using multivariate statistical analysis with principal component analysis biplots (PCA biplot), and Pearson correlation analysis with a significance level of 0,05 using Past 4.03. The results of the physical and chemical analysis of the soil have been reported in previous reports. Most of the most abundant metals were found in the roots of Acacia in the forest, namely Sn (24,67 ppm), in GM, namely: Pb (39,70 ppm), in RT, namely Sn (15 ppm). The highest TF value in tin mining revegetation land < 5 years (Mn>Sn>Zn>Ag>Cu) and BCF (Fe>Al>Ag>Cu>Cr>Mn>Sn>Zn>Pb>Co>Ni) as well as BAF (Fe>Al>Ag>Cu>Mn>Sn>Zn>Ni>Pb>Co>Cr) highest in tin mining revegetation land > 5 years. Acacia has been tested as a phytoremediator of Mn, Sn, Ag, Cu, Zn metals with a phytoextraction strategy from the revegetation area of the Bangka Island tin mine. Concentrations of three metals Cr, Cu, Fe were toxic to Acacia roots. Most of the metal distribution was in the roots. Soil physico-chemical properties contribute to high metal content in Acacia roots, including: P and K potential, P and K available, total of exchangeable cations, Ca, Mg, H, PH H2O, and base saturation.
