Even Your Poop Probably Has Plastic in It, a New Study Has Found

A group of Austrian researchers have found evidence that microplastics – extremely small pieces of plastic beads, fibres, or fragments – accumulate in human faeces.

Scientists from the Environment Agency Austria and the Medical University of Vienna analysed the poop samples of eight participants from all over the world, including Italy, Japan, Poland, the Netherlands, Russia, the United Kingdom, Finland, and Austria.

 

Throughout the study, the participants recorded what they ate in the week prior to their stool sampling. They all drank from plastic bottles or consumed plastic-wrapped foods in that time, according to the study.

All eight stool samples tested positive for microplastics.

According to the study, published Monday in the United European Gastroenterology Journal, up to nine types of plastic were found in the poop samples.

Researchers noted that the microplastics, which can form when larger pieces of plastic break down, could help transmit toxic chemicals and pathogens into the human body. They also noted that they could weaken the immune response of the gut.

Plastic manufacturing has skyrocketed around the world in the last two decades; almost half of all the plastic ever made has been manufactured in the 21st century.

But only 20 percent of plastic is recycled, National Geographic reported, and people continue to buy a global average of nearly 1 million plastic bottles per minute.

About 18 billion pounds of plastic flow into oceans each year. After sea animals consume some of this plastic, humans are likely to ingest it through tuna, shrimp, or lobster, the study said. In addition, humans likely consume plastic that enters food products from food processing systems.

 

Monday's study may be the first to show the presence of plastics in the human gut, and it comes a few months after the World Health Organisation announced it would investigate the potential effects of plastic on human health.

The WHO launched the review in March after a separate study found microplastics in 90 percent of 259 bottles.

Previous studies have shown that plastic is present in the food and drinks we consume, including fish and water, though it remains unclear how microplastics affect our bodies.
