Abstract

This study was aimed at defining the spatial variation in geochemical composition of termite mound soils in the Ika area of Delta State in comparison with surrounding soil samples. Termite mound soils were collected from nine different locations in the Ika area of Delta State, Nigeria. Top-soil samples were also collected from the sampled termitaria at each of the nine sampling locations. Trace elements composition in the termite mound soils was found to be highest in Cr (8.38-23.10 mg kg-1) and lowest in Cd (1.90-3.18 mg kg-1) and was generally higher than in the surrounding top soil samples; Cd (1.80-2.45 mg kg-1) and Cr (7.00-19.10 mg kg-1). The total organic carbon and organic matter contents of the termite mound soil samples were found to be similarly higher in the termites’ mounds than in the surrounding top-soil samples. The total nitrogen and total phosphorus contents of surrounding top soil samples were found to be higher than in the termite mound soil samples. The dispersal and redistribution of epigeal mound by water and wind erosion to the surrounding soil may account for the observed higher levels of total nitrogen and total phosphorus in the surrounding soil samples than in the termite mound soil samples. The spatial variations in the trace element geochemical composition of the termite mound soil samples and the correlation between the levels in the surrounding soil samples were statistically analysed.
