Researchers find microplastics on top of the world at Everest

November 22, 2020 / 9:17 AM
Sharjah24 – AFP: Traces of microplastics have been found close to the top of Mount Everest, a study showed Friday, likely originating from equipment used by the hundreds of climbers who summit the world's highest peak every year.
Fluorescent tents, discarded climbing equipment, empty gas canisters and even frozen excrement have long littered the well-trodden route to the 8,848-metre (29,029-feet) high summit, earning it the name of "the highest dumpster in the world". 

But in the first study of microplastics on Everest, by a research team part of the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition, the tiny pollutants were found as high as 8,440 metres above sea level, although concentration levels were higher at the mountain's base camp.

The findings, which reveal the potential threat to Everest posed by plastic pollutants, were published in the environmental journal One Earth on Friday.

"The samples showed significant quantities of polyester, acrylic, nylon, and polypropylene fibres," author Imogen Napper, a National Geographic explorer and scientist based at the University of Plymouth in Britain, said in a statement.

"It really surprised me to find microplastics in every single snow sample I analysed. Mount Everest is somewhere I have always considered remote and pristine. To know we are polluting near the top of the tallest mountain (in the world) is a real eye-opener."
