Abstract
Dumping sites in general have been noted to be sources of pollution in the environment and e-waste dumping sites are not exempted. A study on the pollution of heavy metals in two local government areas (LGAs) in Ogun State, was investigated. As, Cd, Co, Cr, Cu, Fe, Ni, Pb, and Zn were detected. Cd, Cu were detected in two areas. While Fe, Pb in four areas, and Zn concentrations were above the World Health Organisation permissible limit. Analysis indicates that the contaminant factor (CF) varies from low to severe at both LGAs; however, CF of Cd is severe in all the sites, which signifies that all the areas are not suitable for agriculture. Further results indicate that the Pollution Load Index (PLI) value is greater than one at all dumpsites, signifying that the sites are polluted. Pearson correlation shows a comparatively strong positive correlation (r = 0.826) between Ijebu-Ode and Ijebu-North Local governments. The predominant results suggest that proactive monitoring should be maintained, and remediation is required, including source identification, pollution management, and soil restoration approaches.
