For years, the contamination burden has led the Marmara Sea to death. While the oxygen concentration in the deep bottom water in the Marmara Sea approaches zero, especially the sharks, especially cartilage fish species, escape to coastal areas to survive. At the same time, hundreds of streams flowing into the Sea of Marmara, tea and streams left without treatment, agricultural and industrial waste turning Marmara into the sewer. Although environmentalists, scientists and citizen initiatives have listed their warnings for years, the table does not change. Poisonous arteries flowing on tar day day by day continue to pump death into the veins of Marmara.
Marmara without oxygen
WWF-Türkiye Cinderella Consultant According to Hakan Kabasakal’s latest research, the amount of oxygen dissolved at many depth points of the Marmara Sea has fallen below 2 mg/l. From a depth of 100 meters, in some regions, this amount goes below 1 mg/l, while In Eastern Marmara, there are points where oxygen is reset below 200 meters deep. This means death edict for sea creatures. Sharks and similar species that need high oxygen with their metabolism are either dying or trying to survive by turning to the shore.
Disaster is experienced
One of the main sources of Marmara’s fatal pollution burden is Nilüfer Stream in Bursa. This river flowing tar land is no longer an ecosystem; A chemical sewage discharge. Nilüfer Stream, which is known as Bursa’s ‘Ergeni’, collects all the waste of industrial zones, OIZs and domestic settlements through which it passes through. Turkish Nature Protection Association Science Advisor According to the warning of Erol Kesici, if the necessary measures are not taken, the Sea of Marmara may face a worse picture than the mucshage disaster in 2021.
Need 10 billion dollars
Former Undersecretary of the Ministry of Environment and Urbanization. Dr. Mustafa Ozturk, about 180 streams and streams in the Marmara Basin are polluted by both industrial and domestic wastes, and this collapse will become irreversible if the precaution is not taken. Öztürk stated that Gönen Stream turned into a very dirty water bed. “In order to prevent general pollution in the region, an infrastructure investment of about $ 10 billion is essential. Marmara cannot be saved until advanced biological treatment systems are started“he says.
Nilüfer Most Dirty
Öztürk stated that Nilüfer Stream is no longer a natural river and there is no fish, bird or plant life. “Nilüfer Stream has turned into sewage with domestic and industrial waste water. This tea is one of the most dangerous veins of the Marmara Sea ..
This does not remove the load
Prof. Dr. Bandırma Onyedi Eylül University Faculty Member. Dr. Mustafa Sarı draws attention to the size of the pollution burden carried by the Marmara Sea. According to Sarı’s statement, only 51 percent of domestic wastes in the Marmara Region are purified, while about 70 percent of factories are directly discharged to the river beds without any treatment. This is a burden that Marmara cannot carry. Sarı, “Advanced biological treatment systems can not carry the burden of a population of exceeding 30 million without being implemented. We are all responsible for this environmental collapse, nobody is sinless ” says.
