Researchers use uncrewed aerial systems to sample microplastics in the atmosphere
A team led by CIRES published findings in Scientific Reports on a new method for measuring atmospheric microplastics using an uncrewed aerial system.
Sampling from high altitudes
Previous studies usually collected samples from rooftops, ground locations, or ships. This proof-of-concept study demonstrates that sampling is possible at heights of 100 meters near areas with intense human activity. The researchers successfully used an environmental cyclone sampler mounted on the uncrewed aerial system to collect the particles.
Feasibility for remote areas
The results confirm that this approach is a feasible method for measuring microplastics in the atmosphere. The work establishes a potential framework for future sampling in remote environments such as above the ocean. This technique allows scientists to investigate how microplastics move through the lower atmosphere where traditional methods struggle.
