A new study by Chinese Academy of Sciences researchers has shed light on how microplastics travel and settle in the Qinghai-Xizang Plateau, offering insights to support pollution control efforts.
Using field sampling in the Qilian Mountains, scientists found that microplastics can reach even remote high-altitude regions through long-distance atmospheric transport. While overall levels were lower than in densely populated areas, over 70% of particles were fragmented, indicating prolonged transport and aging.
The study also found that irregularly shaped (low-sphericity) microplastics are more likely to travel long distances, while more spherical particles tend to settle locally.
Researchers say the findings improve understanding of microplastic movement in remote regions and provide scientific support for global pollution modeling and prevention strategies.
