Research: flows after precipitation transfer microplastics to the depths of the oceans

The study showed that the largest flows on Earth can carry dozens of microplastics

kilometers. These data can help predict the location of future “congestion points” of microplastics. This, in turn, can show how these small particles affect marine life.

Researchers noted that annually in the oceansMore than 10 million tons of plastic are emitted. It is estimated that about 99% of them are located in deep-sea areas, often accumulating in underwater canyons. However, it was previously unknown how microplastics can enter the seas and oceans from land. New studies have shown in detail that microplastics can also move in streams after precipitation.

Microplastic not only destroys corals, but also changes their genes and cells.

Distribution of various types of plastic on the marinethe bottom is important because the size and type of plastic particles determines how toxins accumulate on the surface. In addition, it is now possible to calculate the probability of which animals can accumulate particles of this plastic in themselves and how this affects their body.

The next stages of research will include selectionsamples and monitoring of deep-sea underwater canyons. So scientists want to understand how their research can be applied to underwater natural systems and their impact on deep-sea ecosystems.

Previously, researchers were able to find out that plastic,thrown into the environment, breaks up into smaller fragments, called microplastics, if its size is less than five millimeters. Microplastics are widespread in the environment and are absorbed by animals at all levels of the food web: from the smallest organisms up to the summit predators, including humans. So it was discovered that from brewing one tea bag into the human body gets into up to 15 billion microplastic particles.
