Abstract
This study characterised the polycyclic aromatic hydrocarbons (PAHs) in five road paving asphalt samples randomly collected from two hot mix asphalt (HMA) plants in Port Harcourt, Nigeria. The ∑16PAHs of the samples ranged from 103.79 mg/kg - 190.93 mg/kg. Naphthalene, Acenaphthylene, fluorene and benzo(g,h,i )perylene were not detected in any of the samples. The characteristic isomer ratios of the asphalt samples were also calculated to serve as a reference for road runoffs and leachates studies.
