Abstract

An oil-impacted site at Oshire-2 in Niger Delta (Nigeria) was delimited by reconnaissance. Surface and subsurface soils were analyzed for total extractable hydrocarbon content and some physicochemical characteristics. The oil-impacted soils had a mean hydrocarbon content of 1.99 × 103 mg/kg (no overlap in Standard Error at 95% Confidence Limit) and were characterized by an isohyperthermic temperature regime >22°C, high moisture content, high acidity (low soil-pH) and low electrical conductivity. The intense infusion of degradable hydrocarbons at the site must have stimulated aerobic and anaerobic microbial metabolism and so, as oxygen became limiting, utilization of alternate electron acceptors produced an increasingly reducing environment.
