Long-distance movement of microplastics

Nature Communications Microplastic pollution collected at a Key largo, Florida beach State Park. An Ocean Blue Project photo. Microplastics, detected in southern France, could have been transported over 4,500 km from their source, including over continents and oceans, suggests a study published in Nature Communications. The findings suggest that microplastic pollution can spread globally from its sources to remote regions. Plastic pollution has been documented at high elevations and latitudes, and in regions with little local plastic use. The transportation of microplastics through the atmosphere has been suggested as occurring on regional scales. However, it is unclear how widespread this phenomenon is and, if like mercury and other pollutants, there is free transport of microplastics through the atmosphere that enables trans-continental movement. Steve Allen and colleagues collected atmospheric microplastics at the high-elevation Pic du Midi Observatory in the French Pyrenees, south
