Soil samples from three farmlands close to dumpsite and a control station in Port Harcourt, Rivers State, Nigeria were collected at random within a depth range of 0-60cm to evaluate concentration of some heavy metals (Fe, Pb, Cu, Cd, Cr and Ni). The determination of the concentration of the heavy metals was determined using Atomic Adsorption Spectrometer (AAS). The level of all the investigated heavy metals in the selected farmlands were higher than that obtained from the control station. The results obtained revealed that the mean concentrations of the heavy metals in the farmlands were in the range of 199.38±9.15-209.45±15.58mg/Kg for Fe, 1.70±0.09-1.86±0.14mg/Kg for Pb, 0.12±0.03-0.32±0.15mg/Kg for Cd, 2.00±0.05-2.99±0.25mg/Kg for Cr, 2.78±0.42-3.49±0.49mg/Kg for Cu and 2.15±0.34-2.75±0.23mg/Kg for Ni. The level of the investigated heavy metals in the farmlands considering the range of occurrence were in the order Fe > Cu > Cr > Ni > Pb > Cd. The results indicated that the levels of all the studied heavy metals in the farmlands were far higher than those of the control station. Pollution evaluation indices applied in assessing the soil quality as a result of anthropogenic influence were: contamination factor (CF), pollution load index (PLI), contamination degree (CD), modified contamination degree (mCD), potential ecological risk coefficient (Eir), potential ecological risk index (RI), Geo-accumulation index (Igeo) and anthropogenicity. These indices applied showed that the selected farmlands were not contaminated by the studied heavy metals and therefore does not pose any ecological or health risk to the farmland and humans that make use of the farmland for agriculture.
