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
