ClearStatus and prospects of atmospheric microplastics: A review of methods, occurrence, composition, source and health risks
This review summarized the sampling methods, occurrence, composition, sources, and health risks of atmospheric microplastics. Researchers found that airborne microplastics are detected both indoors and outdoors, with fibers being the most common shape, and that inhalation represents an important but understudied exposure pathway. The study suggests that atmospheric transport plays a significant role in the global distribution of microplastic pollution.
Microplastics in the atmosphere: transportation and impact on humans
This chapter reviews the origins, atmospheric transport, distribution, and characterization of airborne microplastics. The authors note that microplastics have been detected in urban, suburban, and remote regions, raising the possibility of long-distance atmospheric transport. The study highlights significant knowledge gaps about the global distribution and health risks of airborne microplastics due to limitations in detection technologies and sampling methods.
The Pollution of Atmospheric Microplastics and Their Potential Risks to Humans
This review summarizes what is known about airborne microplastics—tiny plastic particles floating in the air we breathe—including their sources, distribution, and potential health risks. Fibers are the most common form found in air, and inhalation is an important but underestimated route of human microplastic exposure.
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.
Microplastics in the Atmosphere
This review summarizes the current state of knowledge on microplastic pollution in the atmosphere, covering sources, transport, deposition, and potential health effects of inhaled airborne microplastics.

This review provides a comprehensive overview of methods for collecting, extracting, and identifying airborne microplastics, examining their sources, transport mechanisms, and persistence in urban and atmospheric environments, and establishing a methodological foundation for future research on microplastic air pollution.
A review of atmospheric microplastics pollution: In-depth sighting of sources, analytical methods, physiognomies, transport and risks
This review provides an in-depth analysis of atmospheric microplastic pollution, examining sources, detection methods, physical characteristics, transport mechanisms, and health risks. Researchers found that indoor environments tend to contain higher concentrations of airborne microplastics than outdoor settings, and that current detection methods are limited in their ability to capture the smallest particles. The study emphasizes the need for standardized sampling procedures and more research into the health effects of inhaling microplastic particles.
Atmospheric Microplastics: Perspectives on Origin, Abundances, Ecological and Health Risks
This review summarizes current knowledge about microplastics in the atmosphere, including their sources, how far they travel, and potential health effects from inhalation. Researchers found that airborne microplastics can carry toxic chemicals deep into the respiratory system and may contribute to respiratory problems and other health concerns. The study emphasizes that atmospheric microplastic pollution remains poorly understood due to a lack of standardized measurement methods.
Atmospheric Microplastics and Human Health: Sources, Exposure, and Risks
This review systematically summarizes the sources, distribution, and health implications of atmospheric microplastics in both indoor and outdoor air. The study highlights growing evidence that inhaled microplastics can enter the human body and pose potential risks to the respiratory system, while identifying key limitations and uncertainties in current exposure assessment methods.
Atmospheric Micro and Nanoplastics: An Enormous Microscopic Problem
This review examined atmospheric micro- and nanoplastic pollution, synthesizing evidence that plastic particles are suspended, transported, and deposited globally through atmospheric pathways, concluding that air represents a major but understudied route of human exposure and environmental dispersal requiring integration into plastic pollution models.
Occurrence of Microplastics in the Atmosphere: An Overview on Sources, Analytical Challenges, and Human Health Effects
This review examines microplastic pollution in the atmosphere, covering both indoor and outdoor sources and the challenges of measuring airborne particles. Researchers found that indoor environments, where people spend most of their time, can have particularly high concentrations of microplastics from synthetic textiles and household items. The study highlights that inhaling airborne microplastics is an important but under-studied route of human exposure.

Aerosol mass concentrations and dry/wet deposition of atmospheric microplastics at a remote coastal location in New Zealand
Researchers quantified airborne microplastic concentrations at a remote coastal site in southern New Zealand using both active and passive sampling methods. They found plastics comprised at least 0.14% of total suspended particulate mass, with air trajectory analysis suggesting the Southern Ocean as a source. The study indicates that counting microplastics by number alone may significantly underestimate true atmospheric plastic pollution, since the smallest and most abundant particles escape microscopic detection.
