The findings indicate pyrogenic and petrogenic PAHs comes from different intermediate materials such as asphalt, street dust, vehicular emission and crankcase oil with higher amounts near the city hinterland. Although there has been a decline of PAHs input into the marine environment in recent years, petroleum is shown to be a significant cause of marine pollution since the 1940’s.
