Geochemical Imprints of Petroleum Pollution of Surface Sediments from the Calabar River, Southeastern Niger Delta of Nigeria;pp. 129-150 $100.00

Abstract:
Surface sediments collected from the Calabar River and flood plain soils, Southeastern Niger Delta of Nigeria were characterized and assessed for petroleum pollution using molecular marker, carbon-isotope and Rock-Eval pyrolysis data. Organic matter (OM) contents ranged between 0.10 and 7.22% TOC. Total Petroleum Hydrocarbons (TPH) vary between 18 and 52,544 ppm. Hydrogen index (HI), Tmax and Production index (PI) of 33 132, 344 422oC and 0.10 0.25 respectively show that the entire study area contains terrestrially derived immature type III organic matter contaminated by petroleum residues. A special group widespread over the entire study contains fractions of saturated hydrocarbons (7.3 22.2%), with distinctive chemical features. These include Carbon Preference Index (CPI), unresolved complex mixtures (UCM) of cyclic and acyclic hydrocarbons, and molecular markers such as pristane, phytane, 17α(H), 21β(H)-hopanes (C27 C35), 5 α(H), 14 β(H), 17β(H)-steranes (C27 C29) and 5α(H), 14 α(H), 17α(H)-steranes and were found useful in differentiating organic matter sourced from both biogenic and petroleum residues. Geochemical ratios, C29-sterane {S/(S+R)}/Moretane/C30-hopane, HI/13C and % (SOM/TOC) reveal not only the degree of contamination by fossil hydrocarbons, but a common source from coastal activities.
