Plastics that have been transported in bacteria by sea



Similar substances of the glue that have been banned by bacteria keep small particles of plastic together in the sea to form larger masks, Scottish research has discovered.

During marine water experiments, the micro and nano plastics joined biopolymers made by bacteria to form more clusters within minutes.

Scientists believe this could lead to mistakes of food from marine mammals.

They are also scared that this could change the flow of food from the surface to the floor, which could lead to the creation of deep sea creatures.

Researchers at Heriot-Watt University in Edinburgh used water collected from the Faroe-Shetland and Firth of Forth Channel to establish their experiments.

Plastic was added to the seawater and then incubated in conditions that simulate the surface of the sea.

Within minutes, the pieces of minuscule plastic had been grouped together with other bacteria, algae and other organic particles.

It is said that the scientists have been surprised to find that a large number of biopolymers form most of these plastic hedges.

"This is a first step in understanding how nanoplastics interact with natural biopolymers across the oceans of the world," said researcher Stephen Summers.

"The nanoplastics, which are 100-200 times less than bacteria cells, have actually been incorporated into the agglomerates, which became visible to the naked eye in our laboratory experiments.

"The fact that these constraints are big enough to look up anxiety, as they are likely to be seen as a food source by small marine animals."

Professor Ted Henry, Heriot-Watt, said the masses were "much more complicated than simple pieces of plastic".

"Research like this is beginning to fill in the scientific knowledge gaps, but we need more evidence to effectively prioritize and control plastic pollution," he said.
