Levels, composition profiles and sources of hydrocarbons were analyzed in surface marine sediment samples collected from Khniss Coast in Tunisia. The total Hydrocarbon (TH) concentrations ranged from 2280 μg/g to 7700 μg/g. The sedimentary non-aromatic hydrocarbon (NAH) and aromatic hydrocarbon (AH) concentrations ranged from 1020 to 2320 μg/g, and from 240 to 680 μg/g, respectively. The higher level of total concentration of 17 polycyclic aromatic hydrocarbons ∑17PAHs is equal to 14.59 ng/g. The PAH profiles showed that the ∑4–5-ring compounds were the major PAHs detected in the sampling sites. Characteristic ratios of Anth/(Anth+ Phe), and Flu/(Flu + Pyr) indicated that PAHs could originate from petrogenic and pyrolytic sources. Petroleum contamination associated with increased marine activity and high eutrophization statue in Khniss area which can have side-effects on the ecosystems and human safety, must be controlled.
