Abstract

There areserious concerns about the recent reports of lead poisoning in some parts of Nigeria. The identification of lead mining activities at TungaTsauni, Gurara Local Government Area of Niger State, Nigeriahas actually necessitated this research in order to obtain a tool that can be used to predict the movement of lead in the soilsof the area. As such, two mathematical models have been developed – one using the convection-dispersion transport approach and the other using the simplified model suggested by Tolessa (2004).It was discovered from the results obtained, after the simulations of the model equations with the aid of MathCAd 14, that the concentration of lead in soil at different positions, which indicates its mobility, could be better represented using the model presented by Tolessa (2004)than using the one developed from the convection-dispersion transport approach because the correlation coefficient values obtained when the model suggested by Tolessa (2004) was modeled and simulated for the system considered in this work and compared to the experimental ones were 0.990525, 0.985546, 0.989689 and 0.988302, while those of the convection-dispersion transport approach were -0.67788, -0.71531, -0.70267 and -0.6053, respectively along the North, the South, the West and the East cardinal directions. As such, Equation (5) has been discovered to be a good tool to be used in truly representing the phenomenon of lead metal mobility in the soil of TungaTsauni, Gurara Local Government Area of Niger State, Nigeria. In addition, the developed model Equation (5) is hoped to beapplicable in predicting the lead mobility in the soil so as to ascertain the safe areas for agricultural activities in Tunga Tsauni partof Niger State, Nigeria.
