Microplastics Pollution

Alarm as study shows how microplastics are blown across the world

Microplastic is raining down on even remote mountaintops, a new study has revealed, with winds having the capacity to carry the pollution “anywhere and everywhere”.

The scientists were astounded by the quantities of microplastic falling from the sky in a supposedly pristine place such as the French stretch of the Pyrenees mountains. Researchers are now finding microplastics everywhere they look; in rivers, the deepest oceans and soils around the world.

Other recent studies have found microplastics in farmland soils near Shanghai, China, in the Galápagos Islands, a Unesco world heritage site, and in rivers in the Czech Republic. Humans and other animals are known to consume the tiny plastic particles via food and water, but the potential health effects on people and ecosystems are as yet unknown.

However the ubiquity of the pollution means it needs to be taken very seriously, said Steve Allen, at the EcoLab research institute near Toulouse and who led the new work in the Pyrenees: “If it is going to be a problem, it is going to be a very big problem. I don’t think there is an organism on Earth that is immune to this.” ...

The new study, published in Nature Communications, is the first to show microplastic is raining down just as hard in remote environments and that it can travel across significant distances through wind. The team collected samples from high altitudes in the Pyrenees that were far from sources of plastic waste – the nearest village was 6km away, the nearest town 25km, and the nearest city 120km.
