This study is an attempt to assess the influence of oil storage depot discharges on proximate water sources in Ibadan, southwest Nigeria. Fifteen priority polycyclic aromatic hydrocarbons (PAHs) were examined a total 15 samples (10 groundwater +4 surface samples) utilizing gas chromatography–mass spectrometry, after extraction waters with dichloromethane and clean-up extracts. Results revealed that values overall PAHs (GW) (SW) varied from 0.01 3.45 mg/L (mean = 0.42 mg/L) 0.09 0.05 mg/L), correspondingly. The highest value ∑15 (3.45 was observed at 24 m discharge point. ring wise distribution pattern collected follows order: 2–3 rings >5–6 >4 – low molecular weight (LMW) accounted for 90.73% relative HMW (9.27%) samples. diagnostic ratios suggested pollution likely incomplete combustion fossil fuels, vehicle emissions released petroleum effluents nearby depot. concentration carcinogenic GW SW ranged 1×10−2to 9×10−2 7×10−2 mg/L, correspondingly, which highlights possible human health risks. hazard index (HI) studied via oral ingestion dermal exposure pathways are less than unity, suggesting no adverse non-carcinogenic effects. calculated incremental lifetime cancer risk (ILCR) adults children 10−2–10−3 range, implying noteworthy effects beings, being most susceptible. Correspondingly, dibenzo [a, h] anthracence (DahA) Benzo [a] pyrene (BaP) established be greater threats taken location. advocates complete discontinuance release into neighboring environment.
