GENERAL DATA AND INFORMATION ON THE AGIA ZONI II TANKER WRECK
General information At the crack of dawn on 10 September 2017, on Sunday, at a waterside point on the island of Salamina, the Agia Zoni II tan ke r, while in an idle state, issued a final signal at 02:30 GMT (11:30 UTC) and then wrecked from unclear to date reasons. The sinking of the ship caused a leak of a large quantity of oil products in the tanks, resulting in an oil spill around the Agia Zoni II wreck, which was detected 4 hours after the sinking. The tanker received a load of 1,819 metric tons of fuel on Saturday, although the estimated quantity that it eventually had in its tank before shipping was estimated at ~ 2,570 tons (2,200 tons of fuel oil and 370 tons of marine gas oil). Petroleum products escaped in the marine environment probably at the time of sinking and during the following 10 hours, as at midday, 98% of the sealing of the ship had Μarine Traffic data, been achieved. 2017 The quantity that eventually formed the oil spill, without being able to accurately calculate it, is estimated at 170 tons, or 6.6% of the total quantity. The pollution was first noticed on the eastern coasts of Salamina and the coastal zone of Freattyda and Peiraiki. Within the next 24 hours it spread along the southern coasts of Attica from the area of Palaio Faliro to the Lagonissi region, in the form of discontinued spots.

EMERGENCY PLAN AND RESPONSE TIMELINE FOR THE MANAGEMENT AND CONTAINMENT OF THE OIL SPILL According to the Prevention and Response Plan towards Technological and other Disasters of the General Secretariat for Civil Protection, and since the estimated cargo escaped at sea falls within the 7 to 700 tons range category, the mobilization level of all relevant bodies is estimated at scale 2 (out of 3). The applied plan foreseen for this step requires co-operation between the contingency plans that port authorities, the region and the state authorities apply in similar cases. At 06.00 in the morning, the anti-pollution vessel of the Hellenic Coast Guard arrived. At the same time, the Ministry of Shipping and Island Policy was informed that the process of procuring to private companies the sealing of the ship and decontamination has progressed. At the same time, the Local Plan of Piraeus and the Saronic Gulf was put into effect. In the area, all equipment to be used - floating crane, two tugboats, four anti-pollution vessels chartered by the individual and one of the Coast Guard - was found. The first floating barriers were installed two hours after full immersion. However, a significant amount of petroleum products escaped, probably due to their movement deeper into the water column, to a depth greater than 1 meter (which is the maximum draught of the barriers) with the assistance of underwater dams or above them, due to meteorological conditions in the area that day.
On Monday morning (11/09/2017), on the initiative of the Ministry of Environment and Energy, the situation is characterized as a very special one and calls for the activation of The Independent Coordination Office for the Implementation of Environmental Liability. Since Monday, Environmental Inspectors are in the field. The Ministry, in turn, informs the European Commission and the Secretariat of the Barcelona Convention on the Mediterranean. Decontamination process is aided by the Aktea vessel of the European Maritime Safety Agency (EMSA) (13/09/2017). ISSN 2653-9454 Issue No. 4, November 2017 | 15
EMERGENCY MANAGEMENT OF THE FIRST 24HOURS IN THE FIELD
Laying floating dams around the wreck Laying of floating coastal protection barriers Sealing of wreck tanks
Adsorption of oil from the surface of the sea by means of a tank pump Removal of large contaminated materials Placing special absorbent papers on the water surface
Removal of matter and clay from the coast, covered with petroleum products

THE COASTAL ZONE OF THE SARONIC GULF 18 DAYS AFTER THE LEAK ACCIDENT PHOTOGRAPHIC COASTAL & UNDERWATER SAMPLING ON 28/09/2017
The remediation procedures of the coastal zone, both of the marine environment and the coast, 18 days after the leak accident, are in progress. Specialized collectors of polluting substances gradually remove residuals and carry them for further processing of decomposition. Subsequently, the process focuses on the deeper layers of silt and clay on the beach, as well as the washing of rocky substrates by means of pressurized water.

IMPACT OF THE OIL SPILL ON THE MARINE AND COASTAL ENVIRONMENT
• The presence of oil on the surface of the sea creates anoxic conditions as it interrupts the exchange of oxygen and carbon dioxide with the atmosphere. This automatically reduces the photosynthesis process, resulting in a reduction in the amount of phytoplankton only after a few days.
• Toxicity of oil components can cause abnormalities in reproduction, nutrition and growth of marine organisms, cell lesions and necrosis, anesthesia, and even death. This toxicity can affect humans in the same way , through the food chain.
• Oil particles are secreted unchanged by some organisms. The faeces of these organisms with a density greater than the water are precipitated, leading to sediments and thus affecting the benthic organisms.
• The presence of oil in the sea has the capacity to pick up other fat-soluble compounds existing in the wa te r, such as chlorinated pesticides, etc., ultimately bringing much greater concentrations to the shores.
• The aesthetic pollution created by tartar beads has a serious social and economic impact.
• It affects the populations of marine birds, mammals and reptiles that live and breed in both the open sea and the coastal zone.
• As follows, fish grounds are downgraded and fish populations are reduced with impact on professional and recreational fishing. ISSN 2653-9454 Issue No. 4, November 2017 | 24
IMPACTS OF THE AGIA ZONI II SHIPWRECK ON THE SARONIC GULF
Impacts are divided into three levels interacting with each other. Below, reference is made to impacts on marine and coastal environments as well as on social and economic impacts. • Immediate fish killing due to lack of oxygen in the water column in the spread area of the oil spill, mainly at fish 'entrapment points’. • Immediate killing of birds that have been in contact with the oil spill, along the coastline of southern Attica. • Toxicity exposure on a significant number of marine organisms such as shellfish, mollusks, fish, echinoderms, mammals, birds. • Physical alteration of habitats and destruction of aesthetics of a large part of the southern front of Attica and the eastern coasts of Salamina. • Negative economic impact on leisure centers and small tourist businesses located on beaches that were polluted. • Direct negative impact on tourist flows and tourism demand. Consequently, negative economic impact on the occupancy of accommodation establishments in the area (cancellations and early departures of tourists from businesses situated in the southern suburbs of Attica).
• Severe economic impact on fisheries. Sales of fish dropped by 60%, followed by the reduction of fishing trawlers working on daily basis in Saronikos area. Fishermen point out that the decline in catches in the areas of Piraeus, Alimos, Faliro, Varkiza and Glyfada is noticeable. They also believe that the greatest damage has been caused by overexposure and distortion of the problem by the media, and point out that their area of catch has been moved in sea areas several miles away from the polluting zone.
