How many plastic particles per square metre have been discovered in the world’s oceans?


A simulation of the deep ocean. This experiment, in a large tank in a lab in the Netherlands, shows how ocean currents push mounds of sediment across the seafloor. Mixed into those mounds are millions of tiny pieces of plastic, and scientists have now measured the extent of this seabed pollution.


Prof Elda Miramontes, University of Bremen
We are all aware of all of the plastic that is floating in the ocean, but it only represents one per cent of the whole amount. The rest is somewhere in the deep sea. We found in this area the highest accumulations ever reported in the global oceans and there are 1.9 million particles, pieces, small pieces per square metre.

Studies in 2018 by some of the same researchers revealed just how much plastic pollution was locked in UK riverbeds then flushed out to sea during floods.


These latest experiments, in the Mediterranean, extracted whole chunks of seafloor from depths of up to a kilometre. That enabled scientists to track how the currents carry plastic waste out to sea, where it breaks down. The deep currents then accumulate these millions of fragments into what researchers call microplastic hotspots.

這些最新的實驗在地中海進行,科學家們從深達一公里的海底挖出了整塊的海床。這使他們能夠追蹤洋流是怎樣將塑料垃圾帶到海洋中的,塑料垃圾在海洋中會分解成小碎片。這些深海洋流接著將數百萬個碎片聚積到研究者們所稱的 「微塑料熱點地區」。

The majority of the particles they found were tiny fibres from textiles and clothing that simply slip through the filtration systems in waste water treatment plants.

We’re filling in part of the gaps in our understanding of this missing 99 per cent of plastic. There are fragile ecosystems on the seafloor which depend on the nutrients and oxygen which are being flushed by these ocean currents. These currents are transporting microplastics to the same places that these fragile ecosystems exist.

「我們在一定程度上填補了對下落不明的 99%的塑料認識上的空白。海底有脆弱的生態系統,它們依賴於被洋流沖走的營養物質和氧氣。洋流正在把微塑料輸送到這些脆弱生態系統存在的地方。」

Scientists from the British Antarctic Survey, in another study published this week, revealed that plastic pollution was reaching the shores of some of the most remote islands.


In recent years we have finally started to see the impact that our plastic waste has on the oceans. This research has started to uncover the invisible, long-term consequences.
