Microplastics blowing into remote Pyrenees mountains

"Microplastics have been discovered in a remote area of the French Pyrenees mountains [close to the border with Spain/Catalonia.] The particles traveled through the atmosphere and were blown into the once-pristine region by the wind, according to a new study published in Nature Geoscience.

This is just the latest example of the “hidden risks” posed by plastics that humans cannot see with the naked eye. For now, governments and activists are focused on avoiding plastic litter in the environment, driven mainly by concern for wildlife and worries over unsightly drinks bottles or abandoned fishing nets on beaches. Plastic bag usage has been cut in many parts of the world, and various projects are exploring how to gather up the floating plastic waste in oceans. But little has yet been done to deal with polluting plastic particles that are usually invisible.

There is, however, growing concern about these micro and nanoplastics, classified as particles smaller than 5mm. These come in part from deliberately manufactured sources, such as scrubbing materials in cleaning and cosmetic products, but also from secondary sources, such as the inevitable breaking up or wearing down of larger items such as tires or fibers shed from tumble driers and washing machines. We are becoming increasingly aware of their presence but know surprisingly little about how much is out there, how it behaves in our environment and what the implications are for human and animal well-being.

As more studies publish their findings we are learning that microplastics are more widespread than we imagined, and that they are found in every environmental system investigated. Plastic particles have been found in record-breaking quantities in river sediments in the UK, for instance, while a study in Paris found plastic fibers in wastewater and the air."
