Objective: The objective of this work is the monitoring of pollutants from the Suez bay, industrial zones in Suez and Beaches in Ismailia city. These areas may be considerable amounts received pollutants from the shipping inputs arise from operational activities and deliberating discharges of waste and water tankers. Methods: Eight surface water samples were collected from the area of study, comprises the important parts of Suez Canal. All the oils-extracted from the water samples were analyzed

Results: The results show numerous recent inputs of petroleum products especially crude oils at various locations dissolved petroleum hydrocarbons ranged from 5.639 up to 74.8 and 1.868 to 65.698 mg\ml for summer and winter seasons, indicates chronic oil pollution. The gas chromatographic analysis indicates that oil pollutants extracted from water samples are at different weathering states. pristane\phytane ratio close to unity and low CPI values <1 suggest the petrogenic influence. On the other hand, FT-IR spectrometric analysis confirms the petrogenic nature of pollutants. Conclusions: The extracted oils are different degree of weathering which demotes continuous oils spills or inputs. Some samples display predominant bio-synthesized pristane presumably derived from marine plankton. FT-IR spectroscopic analysis indicates high concentrations of aliphatic hydrocarbons, mono, poly-nuclear aromatic hydrocarbons, and naphthenic compounds. The aliphatic hydrocarbon shows the presence of petroleum pollution with different degrees of weathering effects, mixed biogenic hydrocarbons.
