Aliphatic and aromatic biomarkers for petroleum hydrocarbon monitoring in Khniss Tunisian-Coast, (Mediterranean Sea)
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 Σ17PAHs is equal to 14.59 ng/g.The PAH profiles showed that the Σ4-5-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.
