Abstract:

This work was aimed at determining the heavy metals uptake by pumpkin and water leaf grown at dumpsites in Okrika, Rivers State Nigeria.. Soil samples and vegetable samples were collected from dumpsites located at Abam and Drupabo communities in Okrika, Rivers State, Nigeria. The soil samples and the vegetable samples were analyzed for the heavy metals using atomic absorption spectrometer (AAS). From the results obtained, the concentrations of heavy metals in the soil and vegetables were in the sequence: soil [Fe 1905.02 mg kg,) > Zn (56.2mg/kg) >Mn (47.02 mg/kg) >Ni (4.99 mg/kg) >Cu (4.22 mg/kg) >Cr (3.23 mg/kg) > Pb (1.31 mg/kg> Cd (0.86 mg/kg)] fluted pumpkin leaf [Fe (1562.21mg/kg) > Zn (47.97 mg/kg) > Mn (34.29 mg/kg) > Cu (8.37 mg/kg > Ni (5.92 mg/kg) Cr (4.52 mg/kg) > Pb (1.31 mg/kg) > Cd (0.39mg/kg)]; water leaf [Fe (708.08 mg/kg) > Zn (45.91 mg/kg) > Mn (34.18 mg/kg) > Ni (6.79 mg/kg) > Cu (6.67mg/kg)> Cr (3.75 mg/kg) > Pb (3.69 mg/kg) > Cd (0.58 mg/kg)]. The results obtained from this investigation have shown that soils are contaminated at dumpsites with heavy metals which could be transferable to vegetables grown on dumpsites. It is therefore recommended that efforts should be intensified to discourage the practice of cultivating on dumpsite soils.
