Abstract :
The build-up of heavy metals in agricultural
soils is a growing source of worry due to issues with food
safety, potential health risks, and negative effects on the
environment of the soil. This development required
investigation into the relationship between the quality of
the dumpsite-soil metal and the rate of plant
bioaccumulation. Soil samples were collected at a depth
of 0 -45cm from four municipal solid waste dumpsites
and farmland within Delta State, Nigeria. The municipal
solid waste dumpsite selected are the area with heavy
domestic and industrial waste which were overpopulated. Physico-chemical properties of the soil
samples were analyzed using standard procedures. The
study examined at the levels of heavy metals (Cd, Cu, Pb,
Fe, Mn, and Zn) in the soil and sweet corn that was
wildly growing on farmland that also had soil from a
dumpsite. The statistical analysis of variance software
SPSS 17 for Windows (SPSS Inc., USA) was used to
evaluate the data gathered (ANOVA). The results of the
soil samples' physicochemical analysis showed that the
soils from municipal solid waste dumpsites were
moderately acidic, had sizable amounts of organic
matter, and contained some ionisable inorganic
compounds. The mean concentration of heavy metals
found in the dumpsite was higher than the metals in the
control site. Sweet corn is an excluder plant, a
prospective accumulator plant, and can make an
excellent slope remediation plant, according to the
results of translocation factors (TF) and
bioaccumulation factors (BAF) for heavy metals.
According to the findings, different heavy metals may be
categorized as mild contaminants (Fe, Cd, and Mn),
moderate contaminants (Zn and Pb), and severe
contaminants (Cu). Except for the sweet corn grown in
the control site, the levels of heavy metals in the sweet
corn grown in the plot with amended dumpsite soils
above the WHO/FAO permissible limits. The results of
the t-test showed values of p < 0.05, indicating that there
were significant differences in the content of heavy
metals in the soil and the sweet corn. The study made
several recommendations, including the creation and
enforcement of a rule barring any type of farming on the
dumpsites, moving the dumpsites outside of the city, and
enforcing other environmental protection laws to
prevent the continued accumulation of these metals
there. The findings of this study will be very helpful to
academics and environmental regulators in developing
