Determinate the concentration of individual aliphatic hydrocarbons in water and sediment samples collected from different locations which distributed on Al-Gabal Al-Akhdar coast. The total aliphatic hydrocarbons TALHs in the water samples were fluctuated between (8.680-88.885 μg/L). While in the sediment were ranged between (26.313-1069.183 ng/g). High levels of carbonate were recorded in all sediment samples. The total carbon contents were ranged between (1.15-2.6%). The special TALHs compound ratios Pr/Ph the detection of these two components is often used as good indicators of petroleum contamination while a CPI approaching unity indicates great inputs from aquatic organisms the ratio of (n-C17/pr) and (n-C18/ph) indicating contributions from biogenic origins and contribution from petrogenic sources.
