Source data for "Persistent Influx of Atmospheric Microplastics and Nanoplastics to Mount Everest Driven by Large Scale Circulation"
AI summary Read the abstract
Scientists found that tiny plastic particles, so small some can only be seen with powerful microscopes, are being carried by wind currents all the way to the top of Mount Everest, one of the most remote places on Earth. This shows that plastic pollution isn't just a problem in cities or oceans; it's traveling through our atmosphere and settling even in pristine, hard-to-reach environments, meaning there's likely nowhere left untouched by this pollution, including the air we breathe every day.
This repository contains the source data supporting the study “Persistent Influx of Atmospheric Microplastics and Nanoplastics to Mount Everest Driven by Large Scale Circulation.” It includes the source data underlying all main-text figures (Figures 1–4), together with the corresponding meteorological observations, microplastic measurements and particle-level information , and nanoplastic measurements. These datasets support the analyses of atmospheric microplastic and nanoplastic abundance, composition, seasonal variation, meteorological influences, atmospheric transport pathways, and regional deposition presented in the manuscript.

Scientists found that tiny plastic particles (microplastics and even smaller nanoplastics) are being carried by wind currents all the way to the top of Mount Everest, one of the most remote places on Earth. This shows that plastic pollution has spread through our atmosphere so thoroughly that it can reach even the most untouched corners of the planet, meaning there's likely nowhere left that's truly free of these particles, including the air we breathe every day.
Persistent Influx of Atmospheric Microplastics and Nanoplastics to Mount Everest Driven by Large Scale Circulation
AI summary Read the abstract
Scientists found tiny plastic particles (microplastics and even smaller nanoplastics) blowing through the air all the way up to Mount Everest, one of the most remote places on Earth, carried by large wind patterns from far-off sources. This shows that plastic pollution has spread so widely that literally no place on the planet is untouched, meaning the air we breathe almost everywhere may contain these particles. While this study focuses on tracking where the plastic travels rather than its health effects, the finding adds to growing concerns about how unavoidable plastic exposure has become in daily life.
Source Data Underlying Figures S2, S3, and 4 for Atmospheric Microplastics on Mount Everest
AI summary Read the abstract
Scientists studying Mount Everest found tiny plastic particles (microplastics) falling from the air even in one of the most remote places on Earth, far from cities or factories. By tracking wind patterns, they showed these plastics likely traveled long distances from populated areas, meaning there's essentially nowhere on the planet, including the air we breathe, that's untouched by plastic pollution. This matters because it adds to growing evidence that microplastics are everywhere in our environment, raising questions about how much we're inhaling and what that could mean for our lungs and overall health over time.
Remote Mountainous Area Inevitably Becomes Temporal Sink for Microplastics Driven by Atmospheric Transport
AI summary Read the abstract
A 13-month study of an uninhabited mountainous area in China found microplastics in the air at respirable sizes year-round, with 15 different polymer types detected. Atmospheric modeling traced the sources to populated areas hundreds of kilometers away, showing that wind can carry microplastics to even the most remote locations. The findings mean that virtually no place on Earth is free from airborne microplastic exposure.
Microplastic pollution characteristics and its future perspectives in the Tibetan Plateau
AI summary Read the abstract
Researchers reviewed microplastic pollution on the Tibetan Plateau, one of the most remote places on Earth, and found plastic particles in rivers, lakes, soil, snow, and even the atmosphere near Mount Everest. While concentrations are lower than in populated areas, the presence of microplastics in such a remote region shows how far these pollutants can travel through air and water currents. The findings underscore that microplastic contamination is truly a global problem with no pristine environments left untouched.
