The hottest plastics occupy the Arctic scientists

Plastic "occupy" the Arctic! Scientists found plastic particles in the Arctic ice core Sinochem news media said that a team of scientists led by the United States found tiny plastic fragments in the ice core drilled in the Arctic, which highlights the threat that this increasingly serious pollution poses to marine life in the most remote waters of the earth

according to Reuters on August 14, during an 18 day ice breaker expedition across the northwest passage, researchers used helicopters to land on ice floes and obtained these samples

Jacob Strecker, a graduate student at the University of Rhode Island who participated in the "Northwest Passage Project", said: "we spent several weeks observing what looked like primitive white sea ice floating on the sea surface." He made a preliminary analysis of the ice core on board

Strecker said in an interview on August 14: "after careful observation with appropriate tools, we found that the ice core was obviously polluted - it felt a little like a heavy punch in the stomach."

Strecker and his colleagues found in the ice from Lancaster Strait, an isolated water area in the Arctic region of Canada, that the energy consumption per unit building area of these external walls was 4-5 times higher. They originally thought that this water area might not be polluted by floating plastic relatively

the research team drilled 18 two meter long ice cores at four locations, in which plastic beads and wires of various shapes and sizes were clearly visible

Brian Luce, an oceanographer at the University of Rhode Island and the chief scientist of the expedition, said: "the amount and scale of these plastics are remarkable."

the frustration of scientists is reminiscent of the horror that explorers felt when they found plastic garbage in a submarine in the deepest part of the earth - the Mariana Trench in the Pacific Ocean earlier this year

"Northwest Passage Project" is mainly committed to studying the impact of anthropogenic climate change on the Arctic. The rapid disappearance of summer sea ice is weakening the role of the Arctic as the earth's cooling system

at this time, the experimental force is a large tensile force FM. These plastic fragments - those less than 5mm in diameter are micro plastics - also highlight that the waste problem has become rampant. The United Nations estimates that 100 million tons of plastic have been dumped in the sea so far

the researchers said that the ice samples they collected seemed to be at least one year old and probably drifted into the Lancaster Strait from the more central area of the Arctic

the research team plans to further analyze the samples to support a broader study to understand the damage caused by plastics to large marine mammals such as fish, seabirds and whales

the exploration of the Swedish icebreaker Oden was supported by the National Science Foundation of the United States and the universal material experimental machine of the Hessian Simmons foundation. Each step of the technical reform was the result of engineers' continuous accumulation of experience. The voyage was about 2000 nautical miles (about 3700 kilometers) from July 18 to August 4

in addition, Sandra McClelland, a member of the German American Chemical Council and sales business development manager of Solvay specialty polymers, said that a study published by Chinese and Swiss scientists on August 14 based on samples from the Arctic, Swiss Alps and Germany showed that microplastics were blown far away by the wind and fell when it snowed

the research team of the national Helmholtz polar and Marine Research Center found that the snow from Svalbard in the Norwegian Arctic contained up to 14400 plastic particles per liter. In addition, the content of plastic particles in the snow near a rural road in Bavaria, Germany, is the highest, reaching 154000 per liter

Melanie Bergman, a marine ecologist and one of the research leaders, said that in previous studies, a large part of the large amount of microplastics found in the Arctic was probably brought there from the air. The research results of this project were published in the American Journal progress of science

Bergman said in a statement, "once we determine that air can also transport a large amount of microplastics, this naturally raises the question of whether we breathe plastic and how much."
