Potential toxic elements accumulation in soils and parts of palm (Elaeis guineensis) growing on reclaimed tailings and mined spoils in southwestern Ghana.

This study examined the accumulation of potentially toxic elements (PTE) in oil palm (Elaeis guineensis) biomass, fruits, and soils. 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. PTE concentrations and pollution indices were analyzed via various inferential statistics.

Structure, composition and diversity of restored forest ecosystems on mine-spoils in South-Western Ghana.

In response to national policy obligations, many mining companies in Ghana have restored/reclaimed degraded mined out sites through revegetation. The area extent of such restored areas is unknown and there is also paucity of data on success of restoration, species diversity and compositional dynamics of such restored landscapes, particularly using mixed species. This study assessed stand structure, diversity and composition dynamics of sites restored with mixed species and models species abundance distribution on these sites.

Phytoremediation of petroleum hydrocarbon-contaminated soils with two plant species: and at Ghana Manganese Company Ltd.

The study investigated the effects of (JC) and (VZ) on hydrocarbon concentration levels in mine spoils. A 2 × 2 × 3 factorial arrangement of treatments in a completely randomized design with 3 replications was adopted. With compost amendments, JC caused 78.
