ABSTRACT

 

Roadside soil samples were obtained from Eka Street, Oron Road, Ikot Ekpene Road and Nwaniba Road within Uyo metropolis, Akwa Ibom State. Roadside soils were also obtained from Uwana Lane and used as Control. These samples and Control were analysed for the concentration of Cadmium (Cd), Nickel (Ni), Lead (Pb), Zinc (Zn) and Iron using Atomic Absorption Spectrophotometer (AAS) unicam 939 model. Results obtained indicated the following mean concentration (mg/kg) for metals in roadside soil samples: Cd (2.04±3.65), Ni (20.43± 36.55), Pb (2.74 ± 4.89), Zn (26.24 ± 46.94), Fe (491.79 ± 879.74). While lower mean concentrations of these metals were reported in the Control as shown in the result: Cd (1.38 ± 3.65), Ni (13.07 ± 36.55), Pb (1.73 ± 4.89), Zn (9.68 ± 46.95) and Fe (241.49 ± 879.74). The degree of contamination (Cdeg) ranged between 6.69 and 11.37 indicating moderate pollution status of studied roadside soils by these metals. The geoaccumulation index (Igeo) revealed that the studied roadside soils varied between unpolluted to moderately polluted class. However, the enrichment factor (EF) model analysis revealed that the occurrence of these metals in studied roadside soils were mostly due to natural processes as their enrichment factor (EF) values ranged between 0.5 and 2.0. The environmental and health implications of results obtained have been highlighted.
