![]() T., Zakaria, N., Hanson, J., Tulasi, D., & Enti, S. Experimental studies to examine soil amendment effects on PTE accumulation capacity or removal efficacy by the palm plants at various ages are recommended.Īckah, M., Anim, A. Therefore, phytoremediation of mine spoils with oil palm should be done with caution. These high As contents, in the fruits, may contaminate the food chain and increase PTE-related health risks among human populations. PTE accumulation in the palm biomass reduced soil PTE concentrations, but the soils on these mined spoils were severely polluted. The translocation of Cu and As to the fruits was significantly high on both study locations with TF of As = 9 at GMC. Bioaccumulation factors were significantly higher in roots than in the leaves and fruits ( p < 0.0001) and were greater than 2 at GMC. The PLI of the reclaimed tailings and control sites at Bogoso were 17.98 ± 0.56 and 6.06 ± 0.58, respectively, implying the soils at Bogoso are severely polluted with As, Fe, Zn, and Mn while those of the GMC are unpolluted. The contamination factors, enrichment factors, geoaccumulation indices, and pollution load index (PLI) of soils at the tailings dam and reclaimed sites were significantly higher than the control sites. Soil PTE concentration was however significantly higher ( p < 0.0001) than that of the roots, leaves, and fruits at the Bogoso tailings dam. The PTE (As, Fe, Zn, Mn, and Cu) concentrations in the palm roots were significantly higher ( p < 0.001) than in the soil at Ghana Manganese Company (GMC) Ltd, Nsuta except for As which was significantly higher ( p < 0.0001) in the fruits than the soil. PTE concentrations and pollution indices were analyzed via various inferential statistics. ![]() About 40 soil samples to a depth of 40 cm and 90 palm biomass samples from roots, leaves/stems, and fruits were collected from reclaimed tailings dam and control sites at two mining areas in southwestern Ghana. This study examined the accumulation of potentially toxic elements (PTE) in oil palm ( Elaeis guineensis) biomass, fruits, and soils. ![]()
