Mediterranean 'drowning' in 3,760 tonnes of plastics claims Greek scientific study


The Mediterranean is 'drowning' with about 3,760 metric tonnes of plastic from its shores and surface to its bottom, according to a new Greek scientific study.

Researchers at the Institute of Oceanography of the Hellenic Centre for Marine Research (HCMR), led by Dr. Costas Tsiaras, who published the relevant article in the journal Marine Science "Frontiers in Marine Science", have developed a new model that calculates waste coming from land (rivers, coastal cities, etc.) and ending up in the  Mediterranean sea.

The global production of plastics has been growing every year since the 1950s. In 2019, an estimated 368 million tonnes of plastics were produced worldwide. A percentage of them end up in the seas and oceans every year.

Among them, a large number of invisible microplastics (up to five millimetres in size) and macroplastics (over five millimetres ) are floating in the Mediterranean, a closed sea with a large problem of plastic pollution. The densely populated coasts, fishing, shipping, tourism and so forth contribute to the problem.

Fears are being expressed about the conservation of marine ecosystems since plastic pollution affects all levels of marine biodiversity, according to Greek researchers.

Plastics of all sizes are found on the surface of the Mediterranean, on its shores, on its seabed and in the bodies of fish and other marine organisms. Some of these plastics end up being eaten by humans along with seafood.

HCMR scientists estimate that every year the Mediterranean receives a load of about 17,600 tons of plastics, of which 3,760 tons are currently in its waters. Of the total plastic pollution, it is estimated that 84% ends up on the beaches and the remaining 16% is dispersed in the water  at greater depths or eventually falls to the bottom.

  1. Hello. I work at Bloomberg News, and recently edited this story about plastics pollution in Greece, on the Aegean islands. The problem we cover here specifically is the dependence that has been created for all islanders and travelers to use only bottled water – the forces that led to this situation, and what needs to happen to overcome it.
