Heavy metals in soil and plants will be detected and remedied early, reducing major potential hazards to human health and other ecosystem components. The purpose of this study was to compare the permitted limits set by WHO/FAO standards with the physicochemical features and chosen heavy metal concentrations in soils and edible plants at three separate garbage dumpsites in Nkwerre Local Government Area of Imo State. A soil auger was used to collect soil samples at a depth of 0 – 20 cm, while plant samples were taken from the same source as the soil. As a control, samples were taken from a location with no history of dumpsites. For physicochemical characteristics, standard analytical techniques were utilised, whereas for heavy metals analysis, an Atomic Absorption Spectrophotometer (AAS) was used. In comparison to the control, the soil physicochemical characteristics revealed significantly larger changes (p>0.05). Heavy metal concentrations in soil from site A were: 239.158.26.57 (Fe); 0.0800.008 (Cd); 0.0120.001 (Ni); 1.0400.12 (Mn); 0.8990.10 (Pb); and 14.1231.57 (Zn); and site B were: 24.8542.76 (Fe); 0.0800.008 (Cd); 0.0120.001 (Ni); 1.0400.12 (Mn); 0.8990.10. 15.5361.73 (Fe); 0.0690.09 (Cd); 0.3330.04 (Mn); 0.7670.09 (Pb); 3.0970.34 (Zn), whereas those of site C were: 0.0690.008 (Cd); 0.0560.006 (Ni); 1.1630.13 (Mn); 0.1330.02 (Pb); and 16.0041.78 (Zn) (Zn). Except for Fe and Zn at select sites, the levels of all the metals examined for dumpsite samples were higher than the control but below WHO/FAO recommended ranges. For Fe, Cd, Mn, Pb, and Zn, Talinum triangulare had a bioaccumulation factor (BF) and a transfer factor (TF) better than 1, indicating that the plant may be utilised for phytoremediation. For all of the metals tested, there was a substantial positive association.
