The creature in the deepest sea of ​​the planet also began to be affected by humans

Deep ocean locations that are considered to be the most secure and pristine turned out to be relatively influential.

Throughout history, humankind has done too much harm to the natural environment. Only the sea floor is always considered a pristine area, not affected by negative effects from humans.

However, the sad fact is that we are wrong. A recent study from the University of New South Wales (Australia) has shown that the deepest ocean creatures are poisoned PCBs (polychlorinated biphenyls) - toxic substances that have been banned since the 1970s.

The creature in the deepest part of the planet also began to be poisoned.

Specifically, high concentration PCBs were found at depths of more than 10 km towards the Mariana basin in the Pacific Ocean. The distance from this area to the nearest mainland is Japan up to 1300km.

And yet, the Kermadec groove area, after 10km, located 1,500km north of New Zealand, shows a similar phenomenon. According to researcher Alan Jamieson - research director: " Finding a large amount of toxic substances in far and near untouchable areas on Earth shows that human impact is being underestimated. The legacy we leave behind for the next generation is not something to be happy about. "

"We still think the sea floor is a pristine, safe place with human impact, but our research shows that it is no longer true."

Mariana Trench and Kermadec - 2 seas.

According to experts, toxins have spread so much that the plankton here have also been poisoned, with even concentrations corresponding to organisms in Suruga Bay, Japan. That is where the "most contaminated economic area in the Pacific Northwest" is located.

It is known that PCBs are classified as a persistent organic pollutant (POP), which is used as an insulating and explosion-proof material. Due to the strong toxicity, PCBs were banned in 1970, but the total volume produced since 1930 exceeded 1.3 million tons.

Through many roads, PCBs have leaked into the wild, in which a large amount falls into the ocean. Because of its intractable nature, this chemical is almost non-degradable after decades. It builds up in the food chain, so that when it reaches the bottom of the sea, the toxin concentration here is pushed to extremely high levels.

The poison has spread so much that the plankton here have also been poisoned.

According to Dr. Katherine Dafforn from the University of New South Wales, the author of an essay related to the study: "The sea areas despite temperatures are only about 1 degree Celsius, the pressure is 1000 times the surface, but there is a biological life. However, there is growing evidence that these areas are endangered by humans, particularly environmental pollution. "

Dr PCB said, PCB concentrations in organisms are higher than normal, and even the rate of poisoning is 50 times greater than crabs in China's most polluted rivers.

There is growing evidence that these areas are endangered by humans, particularly environmental pollution.

"Research shows that the seabed area clearly has a close relationship with the surface of the water, no matter how far away. It also means that we need to know what we throw into the water with a dangerous impact. how bad it is " - Dr. added.

The study is published in Nature Ecology and Evolution.
