A Study of Aliphatic Hydrocarbons Levels of Some Waters and Sediments at Al-Gabal Al-Akhder Coast Regions

Hamad M. I. Hasan and Abdalrazk S. A. Mohamad

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.
