Abstract
The presence of abattoir in major cities is of great concern, not only to the public but also to the environmental policy makers. Waste disposal management in the country has not been able to cope with the volume of solid waste generated industrially and domestically. This study therefore, was done to assess the soil of some abattoirs environment in Ekiti State, Nigeria. Soil samples were collected from three different Abattoir sites namely; Atikankan Abattoir (Ado - Ekiti), Ikere – Ekiti Abattoir (Ikere - Ekiti) and Iworoko Road Abattoir (Ado - Ekiti) Nigeria. The physico-chemical analysis, Heavy metal analysis (Atomic Absorption Spectrometer (AAS, VGP210).) and Microbial analysis was carried out on the soils. The results indicated that, the abattoir soils are slightly alkaline with an average pH of 7.23 in Iworoko road, 8.63 in Ikere, and 7.90 in atikankan, the electrical conductivity ranges from1202.00 to 1692μS/cm in the various sampling locations of the abattoir soils; the soil type was found to be sandy clay loam in all the soils in the three locations; the percentage of organic matter (TOM) varied from 1.72 – 5.36mg/Kg within the location points. The concentration of heavy metals are: Cd (from 0.01 – 0.02mg/kg); Fe (30000.50 to 34200.94mg/kg); Manganese concentrations varied differently across the sites with maximum mean concentration observed in Ikere - Ekiti Abattoir (0.18mg/Kg) and minimum at the Iworoko Road Site (0.13mg/Kg Pb (10.48- 30.00 mg/kg) and Ni (0.60 – 1.25 mg/kg). Heavy metal concentrations of the threeabattoir soils fell below the WHO permissible limit. The microbial analysis revealed the population of bacteria and fungi in the soil samples from the three abattoir locations which are considerably high for soils.
