dc.description.abstractSoil, untreated mine water and vegetables collected from irrigation farmlands from Barkin Ladi, Jos South and Bassa local government areas of Plateau state Nigeria. Were evaluated for the level of heavy metals using Atomic Absorption spectrometry. Concentration of heavy metals (Zn, Cd, Pb, Mn) were determined in the samples from the three different Local Government Areas. The analysis was done to evaluate the concentration of heavy metals in soil, water, and some selected vegetables. Zn concentrations in vegetables, soil and water from the three different Local Government Areas ranged from 1.598±0.002 to 0.609±0.001 mg/kg, 1.049±0.001 to 0.549±0.006mg/kg and 0.069±0.013 to 0.019±0.004 mg/1. Cd concentrations ranged from 0.490±0.010 to 0.013±0.001 mg/kg (vegetables), 0.130±0.010 to 0.063±0.007 mg/kg (Soil), and 0.168^0.003 to 0.047±0.001 mg/1 in water. The concentrations of Pb in vegetables, soil and water ranged from 1.664±0.005 to 0.140±0.003 mg/kg, 1.631±0.009 to 0.289±0.009 mg/kg and 0.805±0.002 to 0.362±0.001 mg/1 respectively. The level of Mn ranged from 3.429±0.001 to 0.043±0.002 mg/kg, 3.359±0.002 to 1.124±0.001 mg/kg and 0.226±0.002 mg/1 to not detected. Cd had the highest bioaccumulation index (3.769) for tomato fruit from Bassa LGA while Pb had the lowest bioaccumulation index (0.315) for tomato leaf from Jos south. Zn and Mn concentrations in the samples from the three different Local Government Areas were within the WHO/FAO recommended limit but Cd and Pb concentrations in some vegetables and untreated mine water samples exceeded the recommended limits thus posing danger for human consumption. Cd was not detected in green pepper from Barkin Ladi L.G.A.en_US
