Da there is plastic in the hut.
A team of scientists say they have found tiny plastic particles in human stool from a global sample – and each sample tested positive. A study of this kind confirms, what we have long suspected, that plastics ultimately end up in the human intestine, "says lead researcher Philipp Schwabl, a physician at the Medical University of Vienna.
The small study of the University of Karlsruhe Vienna with the Austrian Environment Agency was presented on Monday at the annual United European Gastroenterology Conference.
"Of particular concern is what this means for us, and especially patients with gastrointestinal diseases," schwabl sai d. "While animal studies have found the highest levels of plasticity in animal studies, the smallest microplastic particles are capable of entering the bloodstream, the lymphatic system, and even the liver, and now that we have the first evidence of microplastics in humans, we need further research to understand what this means for human health. "
To conduct the study, researchers monitored the stool of a group of eight participants from Finland, Italy, Japan, the Netherlands, Poland, Russia, the United Kingdom and Austria , They found particles of polypropylene (PP), polyethylene terephthalate (PET) and others. In total, nine types of plastic were found in the stool samples. The researchers found an average of 20 microplastic particles per 10 grams of stool.
Although the study was limited, research suggests that plastics could be widely used in the human food chain.
Ramifications: Microplastics defined as tiny particles, less than 5mm (13/64 inches). The particles come from a variety of products, as well as from plastics that disintegrate in the environment and find their way into waterways.
Scientists say microplastics could affect human health, starting in the gastrointestinal tract and could impair the immune system's response in the gut, either through accumulation of plastics or through transmission of toxins contained therein.
The researchers were unable to determine exactly where the plastics came from. Each study participant conducted a food diary the week before the stool sample. The diaries showed that participants were exposed to plastic in a variety of ways: eating food packaged in plastic or drinking plastic bottles. None were vegetarians. Six had eaten fish.
"This study is brilliant and ingenious," said chemist and microplastic expert Shari Mason of the State University of New York in Fredonia opposite NPR. Mason was not involved in the study, but she said the scientists confirmed "what so many of us suspected – we're picking up these plastics."
Plastics are increasingly regarded as a global problem. The researchers say that plastic production is growing every year and that 2 to 5 percent of all plastics produced end up in the oceans, where they are eaten by marine animals that can potentially reach the human food chain. Microplastic was found in tuna, lobster and shrimp.
Earlier this year, a team of scientists at Orb, a nonprofit journalist organization, found that a single bottle of water can contain tens, even thousands, of tiny plastic particles. Tests on more than 250 bottles showed almost all contamination by microplastic particles containing PP, PET and nylon. A few bottles showed no presence of plastics. Overall, scientists working with the publication found plastic in 93 percent of the samples.
