Description
Summary:Measurements of the elemental composition of soil samples were carried out using Atomic Absorption Spectrophotometer. The samples were collected from Ogun-Oshun River Basin Development Authority (O-ORBDA) Headquarters, Abeokuta, Nigeria. Samples were collected at a depth of about 10 cm and a total of 24 soil samples were taken from the labelled points, as shown in the map of the project site. The Global Positioning Satellite (GPS) was used to obtain the geographical position of each sample point. Four heavy metals (Th, U, Pb, & Cr), five major elements (K, Ca, N, P & Mg) and five trace elements (Zn, Mn, Cu, Al & Fe) were detected. Phosphorus had the highest average value of (78.71 ppm) while Nitrogen had the least (0.17 ppm). The significance of these results is discussed in the paper.
