Microplastics and nanoplastics in the air: a review
This review examines the occurrence, sources, physicochemical characteristics, and sampling and analytical methods for microplastics and nanoplastics in atmospheric air across urban, industrial, coastal, and remote environments. The authors find that fibers and fragments are the dominant atmospheric microplastic forms, that no standardized sampling methods currently exist, and that both passive and active collection approaches are used across the literature with limited comparability.

Identification and physico-chemical characterization of microplastics in marine aerosols over the northeast Arabian Sea
Researchers collected and analyzed airborne microplastics over the northeast Arabian Sea during two sampling campaigns and found microplastics present in marine aerosols at all locations. Fibers were the most common form, primarily made of polyethylene and polypropylene, likely originating from land-based sources transported by wind. The study provides important baseline data on atmospheric microplastic pollution over open ocean regions that had not been previously measured.
Airborne microplastic particles detected in the remote marine atmosphere
Researchers detected airborne microplastic particles — including polystyrene, polyethylene, and polypropylene — in aerosol samples collected over the remote North Atlantic Ocean far from land. Back trajectory analysis and matching polymer types in both air and seawater suggest the ocean surface itself is a source of airborne microplastics, with true particle counts likely higher than detected since only particles above 5 micrometers were analyzed.
Airborne Microplastics in Workplaces: Preliminary Findings from a Multi-site Investigation of Plastic Handling and Processing Facilities
A multi-site investigation of airborne microplastics in plastic handling and processing workplaces found elevated concentrations compared to outdoor air, with particle morphology and polymer types reflecting the specific plastics handled at each facility, identifying occupational inhalation as a significant exposure pathway.
Characterization of Microplastics in the Atmosphere
