摘要：
This work focuses on the assessment of aliphatic hydrocarbons in sediments collected from the western
Moroccan Mediterranean coasts. Two zones have been chosen for this study. Zone 1 corresponds to Tangier’s bay and
zone 2 corresponding to the fringe between Kabila and Kaâ Srass. The aliphatic hydrocarbons were extracted and
analysed using chromatographic techniques (GC/FID and GC/MS). The results showed a more important accumulation of
aliphatic hydrocarbons in Tangier’s bay if compared with zone 2. Levels ranged within 128.8 to 340.31 μg/g dry weight,
with two exceptions 611.72 and 648.16 μg/g dry weights and from 5.25 to 22.71 μg/g dry weights, for zones 1 and 2,
respectively. Moreover, the aliphatic hydrocarbons distribution proves to be strongly influenced by the nearness to input
sources and by oceanographic and hydrodynamic conditions. Thus, two distribution patterns were observed corresponding
to the two areas studied. Furthermore, the examination of origin fingerprinting criteria proved the biogenic origin related
to phytoplankton, bacteria and continental plant waves. The anthropogenic character of hydrocarbons was also evidenced
especially in Tangier’s bay, by several chromatographic criteria and was confirmed by the presence of hopanes with
predominant C29 and C30 α, β compounds.
