Abstract
The distribution of polyaromatic hydrocarbons (PAHs) at different georeferenced sampling points:
Nwata A, Nwata B, Nwata 3’, Ochani and Eyeyaro in one of the most contaminated mangrove
swamp in Nigeria, Ejamah-Ebubu oil spill site was studied. The physico-chemical analysis of the
sediment samples and trace metals were also conducted. PAHs were analyzed using gas-chroma-
tography flame ionization detection while metals with atomic absorption spectrophotometry
(AAS). The result showed that the total PAHs (summation of 16 US EPA priority PAHs) were present
at all sampling points and the concentration ranged from 0.070 to 5.521 ppm with Nwatu A >
Nwatu B > Ochani > Egeyaro > Nwatu 3’. The pH of the site is acidic. The concentration of trace
metals for most sampling points is iron > chromium > lead > nickel > vanadium. Our result indi-
cates that the concentration of PAHs is at level higher than the permitted level therefore; it is
recommended that Ejamah-Ebubu oil spill site be remediated.
