Abstract
Thirteen sediment samples from different locations in the Niger Delta region of Nigeria were analyzed for the presence
of 16 polynuclear aromatic hydrocarbons (PAHs) via gas chromatography/mass spectrometry. The specific target
compounds for this study included naphthalene, acenaphthylene, acenaphthene, flourene, phenanthrene, anthracene,
flouranthene, pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]flouranthene, benzo[a]pyrene,
benzo[ghi]perylene, dibenz[a,h]anthracene, and indeno[1,2,3-cd]pyrene. Four isotopically labeled polynuclear aromatic
hydrocarbons (acanaphthene-d10, phenanthrene-d10, chrysene-d12 and perylene-d12) were used for internal standardization.
All 16 PAHs were found in most of the thirteen samples with concentration ranging from 0.1 lg/kg to 28 lg/kg. It
was also found that the 5 and 6-ring PAHs were present in higher concentrations than all the other compounds, indicating their high resistance to microbial degradation.
