Abstract

The evaluation of open blazing of electronic waste on the chemical composition of three different soil where e-waste were regularly being burnt with control samples at various distances away from each blazing site at computer village, Ikeja, Lagos, Nigeria was carried out using Atomic Absorption Spectroscopy. The mean concentrations of Pb, Cr, Zn, Cd and Cu from the three locations were found to be 120.3±0.4, 18.7±1.3, 90.3±0.4, 16.4±0.5 and 60.3±2.0 mg/kg respectively. There was gradual decrease in heavy metals concentrations at various distances away from each blazing site as the distances increase which suggested that there were leaching of these heavy metals from ewaste containing substances. Pearson correlation revealed that some of the heavy metals showed both positive and negative correlations with each other. When compared with standard values, only cadmium exceeded the tolerable limit recommended by European Union and USEPA. Thus, open blazing of e-waste contributed to the concentrations of these heavy metals in the soils.
