The invisible micro -plastic is threatening human health

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. At present, China has issued relevant regulations to strengthen plastic governance.

In 2004, Richard Thompson and others of Plond University in the United Kingdom published a paper on the international academic journal "Science" (Science) on plastic fragments in marine water and sediments. , Put forward 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 used the National Key Laboratory's Research Team. padding: 0px; FONT-SIZE: 18px; Text-Align: Justify; Word-Break: Normal; Overflow-wrap: break-word; background-color: RGB (255, 255, 255); Text-indent: 2em; 2em; -Width: 100%; color: RGB (47, 47, 47); Font-Family: Helvetica Neue, Helvetica, Pingfang SC, Hiragino Sans Gb, Microsoft Yahei, \ 5Fae soft black, Arial, Sans-Serif; Letter-; spacing: normal; white-space: normal; ">

Micro -plastic that is ubiquitous

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.

Relevant 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, and try to use products with plastic matte ingredients as much as possible; 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.

Strengthen plastic governance in many places

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.

The Hubei Daily client, paying attention to the major events of Hubei and the world, not only pushing the authoritative policies for users, fresh hot information, and practical convenience information, but also launched a series of features such as reading newspapers, newspapers, learning, online interactives.
