Microplastics have been found in our bodies and the food we eat—and even in remote environments around the world, including seawater and ice in the Arctic. Despite their prevalence, little is known about how they move through the atmosphere. New CIRES-led research, which demonstrates a new method for sampling microplastics in the atmosphere using an uncrewed aerial system (UAS), aims to change that. The findings are published in the journal Scientific Reports.
