This study assessed polycyclic aromatic hydrocarbons (PAHs) and heavy metals in the Bonny River by analyzing water, sediment, and biota samples from fifteen strategically selected stations: Jetty to Mguodeya, Eagle Island opposite Emenike waterfront, 107 Emenike Str waterfront by slaughter, Waterfront by Hospital Management Board, Abonnema Wharf Rd, Oil terminal, Wait and Bush Jetty, Nembe Jetty, Old PH Tourist Beach 1, PH Tourist Beach 2, Borokiri Sandfill 1, Fed. Housing Estate (Jetty), Fed. Housing Estate (Abandoned House), Rd 2 Old PH TWP, 42 Eastern Bye-pass, and Amadi Sandfill. The research design adopted in this study was a descriptive approach aimed at analyzing the presence and concentration of polycyclic aromatic hydrocarbons (PAHs) in surface water, sediments, and biota samples from the selected sampling points along the Bonny River. Standard sampling methods were followed. Sample collection involved obtaining 15 surface water samples, 15 sediment samples, and 15 biota samples, ensuring a comprehensive representation of the aquatic environment. The collected samples were preserved and prepared for analysis, with selected physicochemical parameters of the water, sediments and biota measured using suitable laboratory equipment.
