A Groundbreaking Study Reveals Nanoplastics Pollution in the High Alps Linked to Vehicle Tires
In a recent survey conducted in the remote Alps, shocking results have come to light regarding the significant contribution of vehicle tires to nanoparticle pollution in these pristine mountain regions. Trained mountaineer citizen scientists undertook the arduous task of collecting samples from high-altitude glaciers across the French, Swiss, and Italian Alps. These samples were then meticulously analyzed using a cutting-edge technique known as thermal desorption-proton transfer reaction-mass spectrometry (TD-PTR-MS) to identify the presence of nanoplastics.
Researchers focused on detecting compounds such as polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, polystyrene, and tire wear particles in the collected samples. Out of the 14 remote sites surveyed, a troubling revelation emerged as nanoparticle pollution was found in samples from five of these locations. The team of scientists leading this study published their groundbreaking findings in the prestigious journal Scientific Reports.
The analysis of the nanoparticles unveiled a concerning pattern, with tire wear particles being the most prevalent, accounting for 41% of the detected nanoparticles. Additionally, polystyrene constituted 28% of the nanoparticles, while polyethylene made up 12% of the samples. This discovery sheds light on the pervasive impact of vehicle tire emissions on these high-altitude ecosystems.
The Tire Paradox: Unveiling the Environmental Impact of Vehicle Tires
Further studies conducted in recent years have delved into the detrimental effects of tire particles on various ecosystems. A study published in 2022 highlighted the harmful consequences of marine life exposure to tire particles, showcasing negative impacts on coastal and freshwater organisms. Shockingly, subsequent research revealed an alarming statistic — pollution originating from vehicle tires could be up to 2,000 times more detrimental than emissions from vehicle exhaust pipes.
Statistics compiled by Yale Environment 360 paint a grim picture, estimating that tire particles may constitute a staggering 78% of ocean microplastics. Globally, vehicle tires are estimated to shed approximately 6 million tons of particles annually, underscoring the magnitude of this environmental concern. The pervasive nature of tire pollution is further highlighted by a study that found traces of tire chemicals in human urine samples, indicating the far-reaching consequences of this largely overlooked source of pollution.
A Glimpse into the Future: The Global Atmospheric Plastics Survey
As researchers and environmentalists grapple with the implications of nanoplastics pollution in the high Alps, a beacon of hope emerges in the form of the Global Atmospheric Plastics Survey. Building upon the foundational research conducted in the Alps, trained mountaineers are now embarking on a global mission to assess nanoplastic pollution levels in remote locations worldwide.
Dušan Materić, a prominent bio-analytical scientist and Head of the Research Group for Microplastics, Nanoplastics, and Elements at the Helmholtz Centre for Environmental Research, emphasized the significance of this ambitious study. “It will be the first study of global background nanoplastic pollution,” Materić stated, highlighting the pioneering nature of this research endeavor. By establishing a baseline for nanoplastic pollution, researchers aim to monitor changes in pollution levels over the coming decades, providing invaluable insights into the evolving environmental landscape.
As mountaineers Oliver Graves and Brendan O’Ciobhain embark on expeditions to remote corners of the globe, including the Ellsworth Mountains in Antarctica, the collective effort to combat nanoplastics pollution gains momentum. The Global Atmospheric Plastics Survey stands as a testament to human ingenuity and resilience in the face of environmental challenges, offering a glimmer of hope for a sustainable future.
