摘要：

Physico-chemical analysis of soil samples at an oil spill site in the Niger Delta Area of Nigeria showed that the total hydrocarbon content of top soil layers ranged from 0.8 to 12.4 ppm in the heavy impact zone and the oil had penetrated to a depth of 7.2 m. Hydrocarbon concentration in the medium impact zone ranged from 0.02 to 0.40 ppm while hydrocarbons were not detected in 75% of samples from the unimpacted reference zone. Measurement of heavy metal concentrations in the soils revealed a significant build-up (p < 0.05) of lead, iron and zinc in the heavy impact zone. Other parameters including electrical conductivity, exchangeble cations, available phosphorus and total nitrogen in impacted soils were comparatively low while the total organic carbon was high, compared with the reference site. Textural class of soil from the different depths showed a predominantly brown sand at the top soil, loamy sand at medium depths and grey coarse sand at greater depths.
