Petroleum Hydrocarbon Pollution in Bonny Creek Six Months After the Oil Spill from The Fusokiri-6 Manifold in the Niger Delta

The distribution of petroleum hydrocarbon (Polycyclic Aromatic Hydrocarbon, PAH and Total Petroleum Hydrocarbon) was investigated at the Bonny Creek six months after the Fusokiri-6 manifold oil spillage in the Niger Delta region of Nigeria. PAHs reported for the study are the parental PAHs with rings ranging from 2-6. For the surface water and sediment of Fibiri Creek and NLNG-SPDC site, the total PAHs was <0.01. The PAHs of Iwoama Creek is dominated by Phenanthrene (3-Rings) for both surface water and sediment while the Legakiri Creek PAHs is dominated by Anthracene (3-Rings) in surface water and Phenanthrene (3-Rings) in sediment. The TPH of the range of C8-C40 as well as PAHs were found in all sampled locations. Results indicated that all locations were dominated 1-4-Alkylated-PAH of low molecular weight (2-3 Rings). Oiling was still evident on the water body as observed by the intense discolouration observed during the field reconnaissance survey of the spilled site and evident by the concentrations of TPH and PAHs.
