Popis: This study investigated the level Petroleum hydrocarbon in Ikoli creek, Bayelsa state Nigeria with focus on water and sediments. Water and sediments were assessed using standard analytical procedures. Water from surface levels and sediment samples were collected from five locations in the creek. Soxhlet extraction method and liquid-liquid techniques were used in extraction of the petroleum hydrocarbons (Total Hydrocarbon Content and Total Petroleum Hydrocarbon) from the water and sediment samples collected respectively followed by column clean up. Gas Chromatography-Flame Ionization Detector (GC-FID) was use to analyzed the Target compounds and quantified by integrating the areas of both the resolved and unresolved components. Results of analysis of THC and TPH in water ranges between 0.010 to 0.254 mg/L and Total Petroleum Hydrocarbon (TPH) values ranges between 0.001 to 0.437 mg/L in water respectively. While in sediments the Total Hydrocarbon Content (THC) values ranges between 0.01 to 1.43 mg/kg and Total Petroleum Hydrocarbon (TPH) ranges between 0.001 to 0.44 mg/kg. The THC and TPH value of sediments increases across each sampling station in the study area and these hydrocarbons are repository in nature. The results showed that some sampling station in Ikoli creek were slightly polluted with petroleum hydrocarbons and does not conform to acceptable international guideline, which can cause adverse effects to humans and aquatic life over time.
