Microplasticism occurs everywhere, even in human challenge

Microplasticism has been found in human pallet samples from countries in many parts of the world, according to a small pilot study presented this week at the 26 th annual United European Gastroenterology conference in Vienna, Austria.

The study, conducted by researchers from Wien Medical University and the Austrian Environment Agency, looked at pallet samples from eight people in eight different countries: Finland, Italy, Japan, The Netherlands, Poland, Russia, Great Britain and Austria. Each pallet sample was tested positively for up to nine different plastic types, with an average of 20 plastic particles per 10 grams of stool.

Personally, I did not expect that each test would … [test] … positive, “said lead researcher Dr. Philipp Schwabl from the Vienna Medical School. He and his colleagues found that all eight pallet samples contained polypropylene and polyethylene particles -tereftalat, which are the main components of plastic bottles and plastic bottles. “Is it harmful to human health? It is a very important issue and we are planning further investigations. “

In the study, which is the first of its kind, every person ate their usual diet and kept a food diary during the week leading to their pallet sampling. All participants were exposed to plastic by consuming foods that had been wrapped in plastic as well as beverages in plastic bottles. None of the participants were vegetarians and six of them consumed wild fish.

The reason, Scwhabl says, is whether microplasticism may be “into the bloodstream, the lymphatic system and. .. even the liver. “He finds that in animal and fish studies microspheres have been shown to cause bowel injury and liver stress.

The world produces 400 tons of plastic per year and 80 percent stop depositing in landfills and other parts of the environment. The smallest particles , microplate, varies from 1

0 nanometers – so small are the invisible to the human eye – up to 5 millimeters in diameter. Microplastic – including microfibre from a clothes – floats in the air and is found in most of our bottles and tap water, our beer, our sea, mountain and sea salt and our soil.

“This study is brilliant and brilliant,” says chemist and microscopic expert Shari Mason at the State University of New York in Fredonia. Mason was not involved in the study. “They have definitely determined what so many of us suspect – we use these plastics. “

” The question now, says Mason, is what is retained, instead of being excreted? And what’s its effect? ​​

“We know from the scientific literature that anything less than 150 microns, and especially less than 50 microns , can migrate through the intestine and enter the blood cells and organs, “says ecologist Chelsea Rochman of the University of Toronto, who was not involved in the study.

Not only is plastic’s potential migration throughout the body an concern, but the plastic additives can Many of these additives are known endocrine disrupters. According to Dr. Herbert Tilg, Chairman of the Austrian Society of Gastroenterology and Chairman of the UEG Scientific Committee, the micro roast cancer is one of the factors that contribute to inflammatory bowel syndrome or even colon cancer, which increases in young adults. 19659011] “Colon cancer increases in adolescents, and we believe that either diet or environmental components is a factor,” he says. “Now that we know we can detect microplasticism in humans, we can develop greater studies, both in healthy and ill patients, to find out if they are a contributing factor.” Tilg was not involved in this study.

So how can we minimize our exposure to microplasticism? Rochman says for water, “Reverse osmosis filters are beautiful, and we use them in our laboratory.” HEPA filters can also clean the air of small particles, she says. You can avoid plastic bottles, but plastic containers and containers are everywhere for food; and plastic is everywhere around us.

“Our love affair with plastic is so big,” says Mason. “It will take time to change our current situation. People start looking at truly biodegradable plastic made from hemp or corn starch, and I think it will be the ultimate solution for this multifaceted problem.”

Rochman was not Surprised that microplasticism is found in human feces. “We have abused our waste,” said Rochman, “and it’s back to haunt us on our dining table. Now we literally eat our own garbage. We can do it better than that.”

Meanwhile, Schwabl says
