Abstract: Levels of Polycyclic Aromatic Hydrocarbons (PAHs) in surface water and sediment samples in mini-Welele river in Mgbuosimini community, Rivers State, were assessed in this study using Gas Chromatography-Mass Spectrophotometer. The results for surface water showed highest level of Naphthalene (0.366 ppm) followed by pyrene (0.252 ppm). The results for sediment samples showed highest level of Acenaphthene (12.15 ppm) followed by pyrene (10.48 ppm). These values are higher than their recommended standard limits and were attributed to effluents and spillages from marine transport and artisanal petroleum activities in addition to atmospheric deposition. It was recommended that regular monitoring of activities around the rivers and strict environmental laws governing waste disposal should be enacted and enforced.
