This was with a view to providing information on the level of heavy metals accumulation in the soil and exploring the potential of the plants in phytoremediation. Ten (10) matured specimens each of Zea mays, Talinum triangulare, Amaranthus hybridus, Corchorus olitorius, Solanum nigrum, Bidens pilosa and Laportea aestuans were randomly collected from the dump and control sites. The collected plant samples which were taken to the laboratory were separated into roots, shoot and the reproductives, and oven-dried at 60 °C to a constant weight and ground. Profile soil pits were established at the sites to assess the soil physical and chemical properties. Soil samples were also randomly collected at 0 - 15 cm depth using soil auger from the dumpsite and control site. The collected soil samples were air-dried, ground and sieved through a 2-mm sieve. Both the dried soil and plant samples were analyzed for Mn, Fe, Zn, Cu, Pb, As, Cd, Hg, total C, organic carbon, N, P, Ca, Mg, K and Na using standard methods. The results showed that the levels of nutrients, exchangeable cations and heavy metals accumulation were higher in the roots for most of the plant species in the dumpsite except for C. olitorius that was consistently higher in the control site, while in the shoot, the levels of N and P were significantly higher (p ˂ 0.05) in the dumpsite. Most cations (except Na) were not significantly different (p ˃ 0.05) at the sites. The amounts of Mn, Fe and Zn were significantly higher (p ˂ 0.05) in the dumpsite for all the plants studied except in Solanum nigrum where Fe, Zn and As were higher in the control site. There was also a significant (p ˂ 0.05) difference in the exchangeable cations, heavy metals and nutrients in the soil except for N in the dump compared to control site. The soil profile results showed no clear pattern in the level of nutrients, exchangeable cations and heavy metals determined across the layers in both sites. The levels of nutrients and heavy metals accumulation were significantly higher (p < 0.05) at the dump site compared to the control site. The Translocation Factor was greater than 1 in C. olitorius and Z. mays for all the heavy metals in the dumpsite except for Manganese that had a Translocation Factor greater than 1 in the plants in the dumpsite.The Biological Concentration Factor greater than 1 was only found for Fe in A. hybridus, L. aestuans and T. triangulare in the dumpsite. The Biological Accumulation Coefficient greater than 1 was only found for Fe in Z. mays and C. olitorius in the dumpsite. The study concluded that the dumpsite had impacted positively on the soil nutrients, and the accumulation of heavy metals increased in the plants studied. 2023-05-13T16:31:23Z 2023-05-13T16:31:23Z 2015 Thesis Rufai,A.B (2015).
