A secluded mountain region thought to be free of plastic pollution is in fact blanketed by airborne microplastics on a scale comparable to a major city such as Paris, alarmed researchers reported Monday.

Over a five-month period in 2017-2018, an average of 365 tiny bits of plastic settled every day on each square metre of an uninhabited, high-altitude area in the Pyrenees straddling France and Spain, they reported in the journal Nature Geoscience.

"It is astounding and worrying that so many particles were found in the Pyrenees field site," said lead author Steve Allen, a doctoral student at the University of Strathclyde in Scotland.

The study focused on microplastics mostly between 10 and 150 micrometres across, including fragments, fibres and sheet-like pieces of film.

By comparison, a human hair is, on average, about 70 micrometres in width.

"We would never have anticipated that this study would reveal such high levels of microplastic deposits," added co-author Gael Le Roux, a researcher at EcoLab in Toulouse, in southwestern France.

Plastic litter has emerged in the last few years as a major environmental problem.

Up to 12 million tonnes of plastics are thought to enter the world's oceans every year, and millions more clog inland waterways and landfills.

Plastic takes decades to break down, and even then continues to persist in the environment.

Scientists are only now beginning to measure the damage to wildlife and potential impacts on human health.

A study earlier this year uncovered plastic fragments in the guts of animals living more than 10 kilometres below the ocean surface.

Two whales found beached since the start of the year -- one in the Philippines, the other in Sardinia, Italy -- had 40 and 20 kilos, respectively, of plastic in their stomachs.

Microplastics have also been found in tap water around the world, and even the furthest reaches of Antarctica.

- As polluted as Paris -

"Our most significant finding is that microplastics are transported through the atmosphere and deposited in a remote, high-altitude mountain location far from any major city," co-author Deonie Allen, also from EcoLab, told AFP.

"This means that microplastics are an atmospheric pollutant."

Researchers used two monitoring devices to independently measure particle concentration in an area long considered to be among the most pristine in western Europe.

The nearest village is seven kilometres (more than four miles) away, and the nearest city, Toulouse, is more than 100 kilometres.

While the scientists were able to identify the types of plastic, they could not say with certainty where they came from or how far they had drifted.

Analysing the pattern of air flows, they surmised that some particles had travelled at least 100 kilometres.

"But due to the lack of significant local plastic pollution sources, they probably travelled farther," Deonie Allen said.

Samples -- transported by wind, snow and rain -- were collected at the meteorological station of Bernadouze at an altitude of more than 1,500 metres.

The researchers were stunned to find that the concentrations of microplastic pollution were on a par with those found in major cities, including Paris and the southern Chinese industrial city of Dongguan.

"Our findings are within the range of those reported for greater Paris, and can thus be considered comparable," Deonie Allen told AFP.

"We did not expect the number of particles to be so high."

Disneyland Paris cleans up its act, bans plastic straws
Paris (AFP) April 15, 2019 - Disneyland Paris on Monday announced a series of measures to make Europe's biggest private tourist attraction more environmentally friendly, including banning plastic straws.

The theme park east of the French capital, which draws 15 million visitors a year, is like a small town in its own right, producing 19 tonnes of waste last year.

It currently recycles paper, glass and 18 other types of materials accounting for around half of all its waste, a level it aims to increase to 60 percent in 2020, said Nicole Ouimet-Herter, the park's environment manager.

Starting Thursday it will bin plastic straws, to be replaced with fully biodegradable paper versions that will be distributed only if patrons request them.

The announcement follows a vote last month in the European Parliament to ban single-use plastic products such as straws, cutlery and cotton buds from 2021.

It comes as pressure mounts on companies and citizens to wean themselves off the plastics blamed for clogging up oceans.

Disneyland Paris, owned by The Walt Disney Company, also announced several other initiatives to clean up its act.

Next week, shops in the park will stop handing out free plastic bags, offering instead the option of purchasing bags made of 80 percent recycled plastic for 1 or 2 euros ($1.13-$2.26).

And starting in June several of the park's hotels will no longer stock bathrooms with small bottles of shower gel or shampoo, replacing them with bigger ones that can be refilled.

Euro Disney, the park's operator, said it was also planning to install solar panels on the sprawling 22-square-kilometre site to get more power from renewables.

Currently, renewable energy sources account for only 10 percent of the electricity used.

"We are undertaking concrete actions to reduce our impact on the environment. But we also have the power to dazzle children and want to have a positive influence on them to encourage them to take care of nature," said Mireille Smeets, Euro Disney's director of corporate social responsibility.

Renting flat-pack furniture? Ikea's push to go green
Stockholm (AFP) April 14, 2019
Ikea will start renting and recycling furniture worldwide as part of an eco-friendly drive to address concerns its affordable, flat-pack business model leads to overconsumption and waste. Sceptics see the Swedish giant's initiative as a mere marketing ploy, while supporters see a genuine seachange. Either way, Ikea says it plans to become a circular business by 2030. It has already begun repairing and re-packaging products in every store that have been damaged in transit, as well as allowing cus ... read more
