Scientists find where airborne microplastics really come from: Study
Summary
New research reveals that land sources emit over 20 times more airborne microplastic particles than oceans, challenging earlier assumptions about microplastic origins and concentrations in the atmosphere.
Key Points
- New study shows land sources emit over 20 times more microplastic particles than oceans.
- Previous models overestimated the total microplastics in the atmosphere significantly.
- Researchers used global measurements and refined transport models for better emission estimates.
- Significant uncertainties remain, with a need for more data on particle sources and sizes.
