Abstract

The Assessment of heavy metals and physico-chemical parameters in soil samples from various locations around Dangote Cement Factory, Ibese, Ogun state was analysed. Top soil samples at depth of 0-15cm were taken from the north, south, east and west around the factory. The soil characterization was carried out for pH, cation exchange capacity, organic matter, and heavy metals (copper, iron, lead, zinc and cadmium.) In this study, all the reagents used were of analytical grade, samples for heavy metals were prepared using acid digestion method, the concentration in the samples were determined using Atomic Absorption Spectroscopy (AAS). At the end of the study, it was revealed that the concentration of heavy metals ranged from 2.28ppm to 3.25ppm for Iron, 0.21ppm to 0.28ppm for Cu, 0.01ppm to 0.22ppm for Zn, 0.05ppm to 0.88ppm for Cd and 0.10ppm to 0.18ppm for Pb, with the pH ranging from 5.8 to 7.5. Although, the heavy metals concentration in the samples were below the standard limits set by the United State Environmental Protection Agency, but were found to be higher when compared with the control samples, taken from industrial-free area. Conclusively, the influence of the cement factory on the soil at the time of the study was below the USEPA limit.
