Petroleum hydrocarbons pollution o n the Sudanese Red Sea coastal water

Abstract EN

The aim of this paper is to determine the extent of petroleum hydrocarbons pollution on the Sudanese Red Sea coast (Portsudan harbor and Bashayer Marine Terminal (BMT)), to achieve this goal laboratory work was conducted to determine hydrocarbons concentration.

The highest concentration of Total Petroleum Hydrocarbons (TPH) in seawater was found at strip I (dockyard) with the average of 80.2 mg/l, the next to the highest concentration was generally occurred at strip IV (BMT), the ranges of concentrations were between 5.8 and 24.2 mg/l with mean value of 14.98 mg/l.

Values of oil concentration at strip II (South port) are much lower than those of strip I (6.8 to 10 mg/l).

Higher concentrations, ranging from nil to1320 mg/kg were detected in the sediment samples.

It can be concluded on this basis that most of the Portsudan harbor and BMT suffers from oil pollution in different degrees according to UNEP and AIDMO.

No oil contamination was observed at strip III (North port).

The GC measurements proved those hydrocarbons contaminations were due to biologic and petrogenic origins, most oil samples light and middle fractions.
