Levels Of Polycyclic Aromatic Hydrocarbons in Apparanbie Creek, Niger Delta, Nigeria, Nine (9) Years After Chronic Pollution

This study levels of polycyclic aromatic hydrocarbons in Apparanbie Creek, Niger Delta, Nigeria, 9 years after chronic pollution was conducted in November, 2025. A randomized block experimental design was used. Composite soil samples were collected from three (3) sampling stations and were analyzed for polycyclic aromatic hydrocarbons (PAHs) using standard laboratory method. Sediment analysis revealed detectable levels of PAHs at all sampling stations, demonstrating the persistence of hydrocarbon contamination despite the time elapsed since pollution. Station A recorded the highest sediment PAH concentration (6452.961 mg/kg), followed by Station B (4706.071 mg/kg), while Station C recorded the lowest PAH concentration (2925.477 mg/kg). The study underscores the need for continued monitoring, effective pollution control, and active restoration strategies to enhance long-term recovery of mangrove ecosystems in the Niger Delta
