CHARACTERISATION OF POLYCYCLIC AROMATIC HYDROCARBONS (PAHs) IN ROAD PAVING ASPHALT

Ilechukwu Peter Ifenna, Leo C. Osuji

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.
