[Perspective Club · Ecological Supervision] The cleanest place on the earth found micro -plastic for the first time

Micro -plastic first appeared in the cleanest place on the earth

Researchers collected 19 snow samples from different locations along the Rose Ice Shelf, which were found in different locations, and found micro -plastic in each sample. It is the "cleanest" place called by scientific researchers -Antarctica is not spared. Scientists have found micro -plastic in the deep sea deposition, ocean and surface water of the region, but the micro -plastic is still the first time in snow.

The harm of micro -plastic to humans: may hurt liver and lungs

The diameter is less than 5 mm, and even reaches nano -level. The micro -plastic that is almost difficult to find by the naked eye is unknowingly eating, drinking or sucking into the body. Studies have found that this may become another "invisible killer" of human health.

A few days ago, a research on micro -plastic can hurt liver and lungs on Weibo. Related studies were published on the Environmental Science & Technology. The results of the laboratory show that nano -level micro -plastic may enter liver cells and lung cells and destroy its normal process, which will cause adverse effects on organs.

In the past, people's understanding of micro -plastic was mainly reflected in environmental impact. In 2004, Richard Thompson et al., In the international academic journal "Science", published a paper on plastic fragments in marine water and sediments, proposed the concept of micro -plastic.

In 2016, at the Second UN Environment Conference, micro -plastic pollution was included in the second largest scientific issue in the field of environmental and ecological science research. In 2017, at the Gemphor Group Summit held in Hamburg, Germany, through the "Marine Waste Operation Plan" of the 20th Guard of the Guto, micro -plastic pollution was valued in the global agenda.

In the past two years, scientists have gradually discovered that micro -plastic will hurt human health. In 2021, the research team of the National Key Laboratory of the School of Environmental School of Nanjing University also published a related study in the Environmental Science & Technology, which found that the increase in micro -plastic content in the body may increase the intestine Inflammation.

Micro -plastic, we can get everywhere in our lives

For a long time, plastic is considered an inert. It is believed that after entering the human body, micro -plastic will be excreted from the gastrointestinal tract and gallbladder. However, animal studies have shown that micro -plastic less than 10 μm can pass through the cell membrane into the circulatory system and reach other tissues.

In 2022, the papers from the Amsterdam University Research Team from the Amsterdam University of the Netherlands in the environmental science journal "Environment International" stated that micro -plastic found in human blood, which further caused micro -plastic on human health's long -term impact on human health. Worries.

In fact, the micro -plastic that is difficult to distinguish with the naked eye penetrates almost all aspects of daily life. The above -mentioned research at Nanjing University found that often drinking bottled water, eating take -out food, and participants who are exposed to dust are more micro -plastic in the feces. In addition, bath gels, toothpaste, sunscreen and other personal care products, as well as wastewater produced by washing machines, may contain micro -plastic.

Some researchers have made suggestions that do not abuse plastic products in your life. Straws, plastic bags, disposable water cups, takeaway boxes, etc. do not discard it at will; try to choose degradable plastic products, including choosing wool or cotton when buying clothes, etc. Natural material; when choosing a personal care product, you should also pay attention to the composition table, try not to bring a product with plastic matte ingredients; and to do a good job of garbage classification, it is also conducive to reducing micro -plastic damage, and the use of garbage classification and plastic recycling.

my country has issued relevant regulations in many places to strengthen plastic governance

China's plastic pollution control is also actively promoting, and Shanxi, Henan and other places have issued relevant regulations.

In September 2021, the "Notice of the Ministry of Ecology and Environment of the National Development and Reform Commission on issuing the" Fourteenth Five -Year Plastic Pollution Governance Action Plan "mentioned that it is forbidden to produce ultra -thin plastic shopping bags with a thickness of less than 0.025 mm, and the thickness is less than 0.01 mm. Ethylene agricultural land film, plastic micro -pearl daily chemical products and other products that endanger the environment and human health.

In July 2021, the 30th meeting of the Standing Committee of the 13th People's Congress of Shanxi Province adopted the "Shanxi Province Regulations for Recombinant Unreavble One -Dedicated Plastic Products" and implemented it on July 1, 2022. The provisions clearly clearly implement a list of non -degradable disposable plastic products.

In January 2022, Henan Province announced the "Administrative Measures for the Classification of Urban Wurns in Henan Province" and implemented it on March 1, 2022. Article 16 stipulates that the production, sales and use of non -degraded disposable plastic products in accordance with the law. Article 19 stipulates that catering service providers and catering distribution service providers shall not actively provide consumers with disposable chopsticks, puffing and other tableware.
