Abstract

Abstract: The occurrence and distributions of aliphatic biomarkers in oil contaminated soils from Owaza, Niger Delta, Nigeria, were investigated by gas chromatography-mass spectrometry (GC-MS). The concentrations of the n -alkanes Σ(nC14 to nC29 ) in the soils ranged from 18, 680.4 to 35, 615.8 μg/g (average 24, 664.0 μg/g). The abundance of n -alkanes in the soils extracts show that the effect of environmental degradation on the impacted soils has been minimal. N-alkanes diagnostic indices, source and maturity parameters computed for the terpanes and steranes in the soils extracts indicate Niger Delta oil as the source of contamination. This study reveals the significance of aliphatic biomarkers in serving as organic pollution source indicator.
