Over 90% of table salt is contaminated by microplastics. Asian brands have a higher content of microplastics---what is an acrylic mirror?

Salt is an indispensable seasoning in our daily life, but every time you add salt during cooking, you are likely to add microplastics that are hard to see with the naked eye. Microplastics are formed by the decomposition of larger plastic objects in the environment, and the size is less than 5 mm. A few years ago, researchers discovered microplastics in sea salt. However, it is not clear how widespread the plastic fragments are in this most commonly used seasoning. Now, a new study finds that more than 90% of the salt brands sold worldwide are contaminated by plastics, and sea salt has the highest plastic content. And even the rock salt brand analyzed in the study was found to be contaminated by microplastics. Picture: More than 90% of table salt may be contaminated by plastics. This study was jointly conducted by researchers from South Korea and the East Asia Greenpeace Organization. The results of the study were published in the journal Environmental Science and Technology. The study investigated 39 salt brands and found that only three do not contain microplastics. They are from Taiwan (refined sea salt), China (refined rock salt) and France (non-refined sea salt produced by solar evaporation). This finding is consistent with previous research findings on plastics found in salt, but the latest research emphasizes the universality of plastic pollution. Salt from oceans, lakes and rocks are all contaminated. The study found that the density of microplastics found in different brands of table salt varies greatly, but the density of Asian brands is particularly high. The highest amount of microplastics was found in the salt sold in Indonesia. Asia is an area with a high incidence of plastic pollution, and Indonesia, with a coastline of 54,720 kilometers, was listed as the second most serious country in the world for plastic pollution in an unrelated study in 2015. Sherri Mason, a professor at the State University of New York in Fredonia, had collaborated with researchers at the University of Minnesota to conduct another study on salt. She said: “The new findings increase the impact of microplastics. 'New puzzle piece''. Mason continued: 'The fact that they found that salt microplastics are more polluted in Asia is interesting. Although this is not surprising, you still need data to support it. Early research found that salt products sold in these countries We don’t know how many microplastics are. The new research shows us that microplastics are everywhere.” The new research estimates that the average adult consumes about 2,000 microplastics each year through salt. What does this mean? Still a mystery. The author of the research report, Professor Kim Seung-Kyu of Incheon University in South Korea, said: “The results of the study show that the human ingestion of microplastics through seafood is closely related to plastic emissions in specific areas. In order to limit the microplastics we come into contact with, we need to take measures Preventive measures, such as controlling undesirable plastic emissions, are more important to reduce plastic waste.” Another research report recently published by the University of York in the United Kingdom tried to assess the harm of microplastics to the environment. It concluded that it is not yet clear whether microplastics cause harm. A review of 320 existing studies found that there is a 'major knowledge gap' in the scientific understanding of the impact of microplastics. The problem of microplastics in bottled water is equally terrifying. A recent report found that even half of freshwater insects are also contaminated by microplastics. Although people are working hard to remove the ubiquitous plastic waste from the ocean, there are also other alternative materials that are about to come out, such as biodegradable algae plastics. However, even if these efforts have yielded results, many environments are already polluted, and new processes may need to be established as soon as possible to help filter out the sometimes carcinogenic substances from the products we consume.
