Beirut, International —
Large amounts of the huge oil slick off the Lebanese coast has now sunk to the sea bed, creating a thick carpet of heavy fuel oil up to 10 cm thick, which is suffocating sea life, Greenpeace revealed today.
At a press conference in Beirut, Greenpeace and the Lebanese Union of
Professional Divers screened previously unseen video footage showing
the underwater oil slick covering an area stretching over 100 meters to
the West and in places dozens of meters to the North and South of the
site of the leak. The newly-discovered oil on the seabed could be
brought back to the surface with currents and winds and could lead to
further contamination of the coastline.
"The scene is horrific, the seabed is completely covered with fuel oil
which will threaten marine life for many years to come if it is not
contained and removed immediately" said Mohammed El-Sarji, Greenpeace
activist and head of the Lebanese Union of professional Divers who
conducted several dives in Jieh.
Oil spill expert Professor Rick Steiner from the University of Alaska,
who is in Beirut advising the Lebanese government and various NGOs
commented: "This might the first time ever that seabed contamination
has been documented this clearly. The oil is extensive and very toxic
and a we need to find a way to save the marine environment."
Greenpeace reiterated its call for a thorough investigation and
analysis of the impact of the oil spill, along with other environmental
casualties of the conflict.
Zeina Al Hajj, Greenpeace co-ordinator in Beirut commented "The images
are alarming and it is clear that a full assessment of the extent of
the oil spill will need underwater investigation along the coast as
well as aerial and ground surveillance; the blockade must be lifted for
this work to proceed.
More effort is needed to recover as much oil as possible from
contaminated areas. A full damage assessment must be carried out to
cover all the environmental impacts caused by the war and, as a
priority, caused by this spill."
An estimated 10,000 to 15,000 tonnes of Fuel Oil 1501 poured into the
Mediterranean Sea following the bombing of the Jieh power plant on July
13 and 15. This has contaminated up to 30 areas along 150 km of
the Lebanese coast north of Jieh; however the full extent of the spill
has yet to be fully assessed as aerial surveillance is still not
possible due to an air and sea blockade.
Response to the spill was delayed due to the war and oil recovery and
mitigation only started five weeks after the spill occurred. Even now,
only a limited response is possible due to difficulties in getting more
equipment and expertise into the area, contributing to further
contamination.
Greenpeace has been working to gather information for a post conflict
environmental assessment in Lebanon and will provide the authorities
with the details of this seabed contamination. The organisation
has offered whatever help it can provide to the regional and national
authorities and will be contributing to the mitigation efforts.
Notes to Editor
1. Fuel Oil 150 is a slightly less dense and less viscous heavy fuel oil than standard bunker fuel 180. It is probably a blend of bunker fuel and lighter diesel fractions. Fuel oil 150 is considered to be slightly more toxic than the 180 and would lose a higher percentage of these lighter fractions over time through volatilisation to the air.
2. Once oil is in the sea, the so-called lighter (more volatile) parts or fractions are lost through evaporation, degradation and dispersion, especially in warm waters, such that they should present less of an acute toxicity problem. However, it is still possible for these fractions to cause tainting of fish and shellfish, even when they are present at relatively low concentrations. Other more soluble compounds or chemicals are formed as partial breakdown products as the oil starts breaking into smaller droplets and is attacked by microbes that are able to digest the oil.
