Scientists have discovered microplastic deposits on Mount Everest, at over 8,000 meters above sea level, being the most unexpected place, at the highest altitude, where they have so far reached particles that endanger ecosystems.
Samples collected from the highest mountain in the world have many microplastics present and the cause is still controversial. Fibers of polyester, acrylic, nylon and polypropylene have been found on the mountain, and researchers have two hypotheses: they come from high-performance mountain equipment that uses this material, or they were carried by the wind.
However, how these materials got to the mountain is still debatable. Some believe large objects were lost during ascents, while others say strong winds brought them from the lower levels. Whatever the reason, it is certain that microplastics were discovered in all 19 high-altitude samples collected in April and May as part of Rolex’s National Geographic and Everest expedition.
The highest concentration was found in the base camp – 79 microplastic fibers per liter of snow – which is a level that damages ecosystems.
The evidence was studied by the University of Plymouth and in a press release, Professor Richard Thompson said:
“Since the 1950s, plastics have been used more and more for their practicality and durability. However, these qualities largely create the global environmental crisis we are seeing today.
There is now global recognition of the need for action, and Nepal has also imposed regulations on mountain expeditions to try to limit the environmental problems created by waste.
This study and our continuous research underline the importance of creating materials that have the qualities of plastic, but without a lasting and harmful heritage ”.
