Microplastics Found In 100 Percent Of Humans Studied: Research

Plastic is apparently showing up in all of us

In the first study of its kind, Austrian researchers have tracked the movement of microplastics into human beings. The results show that the plastic that is a ubiquitous element of human life is now also a constant element in the human body.

The research was presented at this week at UEG Week in Vienna, Austria, the largest gastroenterology meeting in Europe.

Two Austrian researchers, Dr. Philipp Schwabl from the Medical University of Vienna, and Dr. Bettina Liebmann, from the Environment Agency Austria, studied participants from countries including Finland, Italy, Japan, the Netherlands, Poland, Russia, the UK and Austria.

Microplastics are particles of plastic less than 5 mm in size. They are often tiny plastic beads that are put in cosmetic products. A few nations, including the U.S., the UK and South Korea, have banned microbeads. But microplastics also are created when larger pieces of plastic break down over time, and plastic in general is everywhere. The U.N. estimates that about 8 million metric tons of plastic end up in the world’s oceans every year. And the World Economic Forum estimated that Americans threw away over 33 million metric tons of plastic in 2014.

But this study, which was small, suggests that plastic, whether it’s bad for us or not, is already in all of us.

Study participants were asked to keep a food diary for seven days prior to taking part in the test. Then they turned over stool samples to the researchers who then looked for microplastics.

And they found them. Every single stool sample tested positive for the presence of microplastic, and up to nine different plastic types were identified.

Where is the plastic coming from? In the cases of this study, the plastic that showed up in people is associated with eating plastic wrapped foods, and drinking from plastic bottles. But most of the participants also ate fish, so Schwabl says that right now, “no exact conclusion on plastic origin can be made” on exactly where the plastic is coming from. Future studies should narrow that down.

What is it doing to us?

So is all that plastic making us sick? Schwabl says, for now, there are no definitive studies that suggest a danger to humans. But he says that in “animal studies, it has been shown that microplastics may cause intestinal damage, remodeling of the intestinal villi, distortion of iron absorption and hepatic stress.”

And the concern is “what this means to us, and especially patients with gastrointestinal diseases,” Schwabl says. “While the highest plastic concentrations in animal studies have been found in the gut, the smallest microplastic particles are capable of entering the blood stream, lymphatic system and may even reach the liver.”

He was surprised, he says, to find that plastic is apparently showing up in all of us, and he expects the amount collecting in our bodies to keep increasing, unless the world drastically changes its use of plastic. (VOA)

The Flamboyant Plastic Waste Boat Reminds The Global Policy-Makers The Urgency To Address Impact Of Plastics on The World’s Marine Environment

This flamboyant nine-metre-long dhow, made from 10 tonnes of plastic waste collected from Kenyan beaches and roadsides, sailed more than 500 km from the idyllic island of Lamu to Zanzibar this year with a message to eliminate single-use plastics.

And it also reminds the global policy-makers the urgency to address and lessen the growing impact of plastics on the world’s marine environment.

The Flipflopi dhow was positioned right at the entrance of the conference venue in the UN Environment headquarters in Nairobi where over 4,700 delegates from 170 countries gathered for the week-long UN Environment Assembly, the world’s highest-level decision-making body on the environment.

“Marine plastic litter pollution is already affecting more than 800 marine species through ingestion, entanglement and habitat change,” UN Environment’s coral reef unit head Jerker Tamelander said.

“Waste continues to leak from land and coral reefs are at the receiving end. They also trap a lot of fishing gear as well as plastic lost from aquaculture. With the impacts of climate change on coral reef ecosystems already significant, the additional threat of plastics must be taken seriously.”

The majority of marine litter – between 60-80 per cent – is composed of plastic.

Only nine per cent of the nine billion tonnes of plastic the world has so far produced has been recycled.

The overwhelming majority of plastics – comprising drinking bottles, bottle caps, food wrappers, grocery bags, lids and straws – are designed to be thrown away after a single use, ultimately ending up in landfills and polluting the environment.

“The first leg of the journey is over, but the journey continues,” Kenyan entrepreneur and Flipflopi project leader Dipesh Pabari told reporters here.

“When you are on the boat and you come to know that it’s made from your toothbrushes and Pet bottles. You will ask how and that is the real story,” he said.

Coming from a family of carpenters and dhow builders in Lamu, an island off the North Coast of Kenya, Ali Skanda is intimately familiar with what goes into building a dhow – a sailboat that has been used in East Africa for more than a thousand years.

On its maiden 500-km-long sojourn, supported by the UN Environment’s Clean Seas campaign, the Flipflopi stopped at towns and cities to sensitize the communities on ways to cut down use of single-use plastics.

A report, Plastics and Shallow Water Coral Reefs, released at this UN Environment Assembly, which focus on innovative solutions for environmental challenges, identifies a number of knowledge gaps that must be addressed to strengthen the scientific evidence base for action on marine plastics that impact coral reefs.

Inspired by 15-year-old Swedish climate activist Greta Thunberg, activist Rebecca Freitag, 26, a UN delegate for sustainable development from Germany, told IANS that the youth should be given participation in environment talks as they comprised 25 per cent of the global population.

Before coming to the UN summit, she collected the plastic waste from roadsides of Kenya, which introduced the world’s toughest laws on single-use plastic bags two years ago, and got her dress stitched to spotlight solutions for the growing impact of plastics on the world’s marine environment.

The Flipflopi is now ready for a voyage next month for a greater political and social awareness of the issue of plastic pollution.

“Now we want to build a 20-m long boat that is capable of sailing to South Africa and beyond,” Pabari said.

For this, $1.5 million is required.

The Flipflopi team has had to pioneer new techniques to craft the dhow’s various components.

Every single element of the boat has been constructed by hand and the whole boat has been clad in colourful sheets of recycled flipflops.

These flipflops have been collected on beach cleanups on Lamu’s beaches, where they are among the most prolific items found. (IANS)
