Abstract
In this study, we report on the analytical assessment of heavy metals contents of
soils collected from different dumpsites in Wukari and environs. The levels of Cu, Cd, Pb,
Fe and Zn metals were determined and the data obtained was subjected to pollution
evaluation methods such as contamination factor (CF) and pollution load index (PLI). The
contamination factors (CFs) revealed a moderate to extreme contamination of the dumpsites
and a decreasing trend in the heavy metals concentrations was observed in soils collected at
about 100 metres from the respective dumpsites which indicated some leaching of the metals
from the dumpsites to adjacent environment. The pollution load index (PLI) showed that
some of the dumpsites are severely polluted as the PLI of the metals from each sample site
exceeded the PLI of the background (control) sample (0.2). Spearman’s rank correlation
analysis showed clear correlations (psource
