Abstract

Field work has been carried out to identify the occurrence of oil and oil by- product pollution from the Red Sea coast of Hodeidah city, was evaluated from December, 2021 to June, 2022. Surface seawater samples were collected from four stations and extracted using standard methods. The extracts were subsequently analyzed by gas chromatography-flame ionization detection. EPH aliphatic hydrocarbon standard 14 components (C9 – C36), high performance liquid chromatographic (HPLC) grade solvents and analytical grade reagents used for this work. The total concentration of aliphatic hydrocarbons n-alkanes (TPH) in surface seawater samples ranged from 9400.5 μg /l at Hodeidah harbor to 2409.7 μg /l at Hodeidah Power Plant in winter and from 4880.9 μg /l at Hodeidah Harbor to 1109.1 μg /l at Hodeida Power Plant in summer. This pollution is a consequence of localized oil operation and /or heavy ship traffic. The investigations in These locations can serve as a reference for future evaluations and studies.
