Abstract: This study aim to evaluate the remediation of heavy metals contaminated soils in Port Harcourt environment. Four samples from four locations within the foreshore were investigated for four months. The findings from the parameters analysed show SEM values of pH as 7.60±0.10, Temperature 30.25±0.25, Total hydrocarbon content 47.08±6.71, Zinc 6.82±0.51, Lead 0.35±0.06, Cadmium 0.0025±0.0009, Copper 0.08±0.01, Nickel 0.05±0.01mg/kg, respectively in diesel contaminated soils when compared with the SEM values of control. The effect of contaminated and treated soils on heavy metals reveal that soils contaminated with diesel (P1) and spent oil (P2) show increase in SEM values when compared with control. However, there was a decrease in the concentration of heavy metals when soils polluted with Diesel were treated with NaNO3 + K3PO4 (T1), and with NH4NO3 + K3PO4 (T2), respectively. Similarly, soils polluted with spent oil and treated with NaNO3 + K3PO4 (T3), and the others treated with NH4NO3 + K3PO4 (T4) also showed a decrease in the concentration of heavy metals, respectively. It was therefore concluded that impact of heavy metals on soils aggravated by oil spills was remediated by the application of sodium nitrate/Potassium phosphate or Ammonium nitrate/Potassium phosphate, thus establishing the fact that these chemicals can serve as a good option in any remediation process of the soil. However, Ten Percent Sodium nitrate/One Percent Potassium phosphate (10% NaNO3 + 1% K3PO4) remediated better than Ten Percent Ammonium nitrate/One Percent Potassium phosphate (10% NH4NO3 +1% K3PO4) and was more economical for the remediation of heavy metals.
