Levels, distribution and characterization of Polycyclic Aromatic Hydrocarbons (PAHs) in Ovia river, Southern Nigeria

The concentration and distribution of Polycyclic Aromatic Hydrocarbons (PAHs) in surface water, sediment, and fish (Clarias gariepinus) samples collected from Ovia River, Southern Nigeria were evaluated, to assess the contamination profile of the river. The concentrations of PAHs were measured to reflect the spatial and monthly distribution of PAHs in the matrices. Mean concentrations of total PAHs (∑PAHs) in surface water samples ranged from...
