Microplastics catch a ride in the atmosphere

Summary
Researchers used modeling to show that oceans are a net source of airborne microplastic pollution, releasing particles that are then carried around the planet by atmospheric currents. This suggests humans can be exposed to microplastics through the air they breathe, far from any original pollution source.
