The uncontrolled dumping of solid waste is a risk factor for soil and groundwater contamination. Indeed, the buried waste generates a strong accumulation of metallic trace elements in the soil. The objective of this study is to investigate the impact of the Akouédo landfill on soil metallic trace elements. Soil samples (0-20 cm) were taken from the control site (soils without residues) and the three sites DAK, DAD, DJD, which correspond, respectively, to older residue soils, aged 30 years, older residue soils, aged between 20 and 30 years and young residue soils, aged 10 years. Atomic Absorption Spectrometer (AAS) analysis of trace metals showed higher concentrations of Zn, Pb, Cu, Cr and Cd in the tailings soils than in the control site.
