Microplastics Are Literally Raining from the Sky—Even in Remote Mountains

2. Atmospheric Transport: How Plastics Reach Remote Peaks

Scientists have established that atmospheric transport plays a crucial role in spreading microplastics far beyond their points of origin.
Wind currents and weather systems can carry these particles thousands of miles from urban, industrial, and coastal areas.
Microplastics become airborne through mechanisms such as wind erosion, urban dust, and even ocean spray.
Storms and shifting airflows can then deposit them onto remote mountain peaks, underscoring the profound connectivity of Earth’s systems.
