dc.description.abstractPAHs in the Lagos lagoon are high enough to raise concern over possible adverse effects on aquatic organisms and human health. Their spatial distribution in the sediment was largely dependent on the proximity of the sediment deposition site to known sources of pollution. Due to their tendency to accumulate in sediments at the bottom of the food chain, PAHs in the lagoon could pose a toxicological threat to benthic organisms and their predators. In this study, the PAH levels in the sediments of the lagoon at twelve locations were evaluated. This work is a follow-up on an earlier paper showing the levels of PAHs in the water samples of the lagoon. All sixteen EPA priority PAHs were found in eight of the locations. Significant amounts of most of the PAHs were found in all the sediments throughout the year. The higher PAHs were more abundant and distributed across the lagoon. Bioavailability assessment revealed that the PAHs were not bioavailable. Adjusted Equilibrium Sediment Benchmark Toxic Units ΣESBTU revealed that the lagoon sediments at all the locations were not toxic to aquatic life.en_US
