Microplastics have been discovered in humans for the first time. This is a concern

"This is the first study of its kind and confirms … that plastics finally reach the intestine," said Dr. Philipp Schwabl, principal investigator who presented the results of the conference at the meeting of the United European Gastroenterology.

"While the intestine has the highest plastic concentrations in animal studies, the smallest microplastic particles are able to penetrate the bloodstream, the lymphatic system and can even reach the liver. we need more research to understand what it means for human health. "

Microplastics are plastic particles smaller than 5 millimeters and are used in various products. They are also formed when large parts dissolve under the effect of inclement weather, degradation or wear.

Studies show that microplastics – common products ranging from synthetic garments to road paints – are present in 83% of tap water samples, all German beers and even in European rainwater.

Experts worry that microplastics in the body can damage the immune system, trigger inflammation and help carry toxins such as mercury or pesticides into the body. In marine mammals, plastics are thought to impair fertility.

The study involved eight people from Finland, Italy, Japan, the Netherlands, Poland, Russia, the United Kingdom and Austria. Their food diaries showed that all had been exposed to plastic during the week, either by eating plastic-wrapped food or drinking from plastic bottles. Six of them consumed sea fish, often microplastics.

Dr. Stephanie Wright, a researcher at King & # 39; s College London, said: "The fact that so many different polymers have been measured suggests a wide range of sources of contamination, which is a matter of concern. Sizes reflect our actual exposure or if smaller sizes are used to be retained or able to cross the intestinal wall.

"What may be more of a concern for these large microplastics is whether the badociated chemical contaminants leach out during the pbadage of the digestive tract and accumulate in the tissues."
