Distribution and sources of polycyclic aromatic hydrocarbons (PAHs) in surface sediment samples collected in South China Sea

Petroleum pollution is one of the pollution that needs serious attention from world. Petroleum is worldwide used and introduced to aquatic environment through accidental oil spill, discharge from routine tanker operations. In other case, land based pollutants are contributed by rainfall and runoff w...
