The present study aims to evaluate the potential ecological risk (PERI), pollution load index (PLI) and Geo-Accumulation Index (Igeo) of soil pollution by heavy metal around the solid waste dumpsites in Warri and Environs. The concentrations of Pb, Cu, Ni, Cr Zn, Cd, Fe and Mn were monitored using atomic absorption spectrophotometer (Unican 929) for 12 months in the selected dumpsites. The spatial variation of Pb, Ni, Cr and Zn showed no significant difference across the sampling location when subjected to one-way ANOVA while evaluation of PLI reviled a value of less than one in all the sample location which indicates no pollution. PERI was evaluated with a value of ER < 30 across the sampling locations which indicates slight pollution and Igeo result showed that the soil at all the study areas are practically uncontaminated by heavy metal. The concentrations of heavy metals in the soil within the vicinities of the dumpsites were within the DPR (2002) stipulated levels. These findings suggested some managerial strategies to avoid escalation of soil contamination by heavy metal at the selected dumpsite and other similar areas elsewhere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
