Abstract
A survey of heavy metal concentrations in some selected soils
in Akwa Ibom State was carried out using UNICAM 939/969 Atomic
Absorption Spectrophotometer. Results from the analysis of ten soil samples
in different locations showed varying levels of Ni, Cd, Zn, Pb and Fe higher
than the recommended levels for soils in developing countries for majority
of samples. Samples, located in the vicinity of automobile repair workshops
had the highest concentrations of Ni and Pb. The soils had a pH range of
5.8-9.3, while the percentage organic matter ranged from 2.70-6.22. These
results suggest that the soils investigated are contaminated with heavy metals
and may not be suitable for crop cultivation.
