Abstrakt: This study investigates aliphatic and polycyclic aromatic hydrocarbons in sediments from offshore Ghana, focusing on their distribution, sources, and ecological risk. Samples were collected from 15 sites near Deep Water Tano and West Cape Three Points blocks. GC-FID and GC-MS analyses revealed higher concentrations in West Cape Three Points compared to Deep Water Tano. Bayesian source apportionment indicated microorganisms as the primary contributor to AHs in both areas. For polycyclic aromatic hydrocarbons, pyrogenic sources dominated in Deep Water Tano (63.3 %), while grass/coal/wood combustion was primary in West Cape Three Points (60 %). Probabilistic risk assessment identified benzo[a]pyrene as posing the highest ecological risk. This study demonstrates the utility of Bayesian methods in identifying hydrocarbon sources and highlights the importance of species-specific sensitivities in ecological risk assessments, providing valuable insights for marine environment management.
