- Abstract
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.
