Correlation between wood dust and soil samples at Lanny Dot sawmill indicated Co, Mn, Fe exhibited moderate positive correlation; Ni, Zn, and Cr showed weak correlations while Pb displayed strong negative correlation. At Falex, Co, Ni shows moderate positive correlations; Cr and Cd displayed weak positive correlations, while Mn and Pb showed low negative correlation. Ifelodun sawmill indicated Cu and Zn exhibited moderate positive correlations while Mn, Ni and Cd displayed weak and low negative correlations, Pb indicated moderate negative correlation. Metals with moderate positive concentrations in each locations suggest that, their concentrations in the surrounding soil may be partially influenced by deposition from sawmill activities. Metals with weak positive correlations displayed limited transfer from wood dust to the soil. Metals with strong and weak negative correlations indicating that the concentration of these metals in the environment does not readily transfer from atmospheric deposition into the soil matrix. The study shows that concentrations of Co, Mn, and Fe (at Lanny Dot); Co, Ni (at Falex); and Cu, Zn (at Ifelodun) may be influenced by deposition from sawmill activities while, concentrations of other metals in each location indicated limited transfer from dust into the soil.
