ClearAtmospheric chemistry of microplastics: Transport, environmental impacts, and governance
This article reviewed the atmospheric chemistry of microplastics, examining their sources, environmental transport, deposition, chemical transformations in the atmosphere, and governance frameworks. It found that airborne MPs travel globally, undergo photochemical aging, and deliver plastic-bound pollutants far from their emission sources.
Various Perspectives on Occurrence, Sources, Measurement Techniques, Transport, and Insights Into Future Scope for Research of Atmospheric Microplastics
This review synthesized current knowledge on atmospheric microplastics, covering their sources, occurrence across global regions, measurement techniques, and transport mechanisms, while identifying key research gaps for future investigation.
Microplastic aging and adsorption in the atmosphere, and their associated impacts on various spheres of the earth: A review
This review examines how microplastics travel through the atmosphere and change during transport due to sunlight, wind, and interactions with other air pollutants. These aging processes alter the surface chemistry of microplastics, affecting which toxic chemicals they can absorb and carry to new locations. The atmospheric pathway is a major route for spreading microplastic contamination globally, including into remote areas and into the air people breathe.
An Atmospheric Chemistry Perspective on Airborne Micro- and Nanoplastic Particles
This perspective paper highlights that airborne micro- and nanoplastics are an understudied form of air pollution that undergoes chemical changes in the atmosphere, potentially making the particles more harmful when inhaled. The authors call for atmospheric scientists and microplastic researchers to work together to better understand health risks from breathing in these particles.
A review of microplastics pollution and its remediation methods: Current scenario and future aspects
Researchers measured microplastic concentrations in atmospheric deposition at remote mountain sites in the Pyrenees, detecting an average of 365 particles per square meter per day. The findings confirm long-range atmospheric transport of microplastics far from pollution sources.
Atmospheric Microplastic Transport
This review examines atmospheric transport of microplastics, covering emission sources including roads and oceans, the meteorological and particle-characteristic factors influencing transport and deposition, and the cycles by which microplastics are redistributed to remote environments including high-altitude and polar regions.
A Review of Atmospheric Micro/Nanoplastics: Insights into Source and Fate for Modelling Studies
This review synthesizes current knowledge on sources, atmospheric transport, and environmental fate of micro- and nanoplastics in the atmosphere, identifying key knowledge gaps including the long-range transport potential, dry and wet deposition rates, and health implications of inhaled airborne plastic particles.
Current understanding of microplastics in the environment: Occurrence, fate, risks, and what we should do
This review synthesizes current knowledge on microplastic occurrence, environmental fate, and risk across marine, freshwater, and atmospheric compartments, noting that both the physical particles and the chemicals they carry pose hazards. The authors call for a more integrated risk assessment framework that treats microplastics as both a pollutant and a carrier of other pollutants.
Microplastics in Atmospheric Pathways, Depositions, and Remediation Techniques
This review examines airborne microplastics -- fibers, fragments, and films between 1 micrometer and 5 mm -- found across the atmosphere, hydrosphere, and lithosphere, discussing their sources, transport pathways, and remediation technologies. The authors highlight growing global concern about inhalation exposure and assess current and emerging techniques for atmospheric microplastic removal.
A Review of the Sources, Environmental Behaviours and Human Health of Atmospheric Microplastics
This review examined sources, environmental behaviors, and human health impacts of atmospheric microplastics, distinguishing indoor from outdoor MP exposure and summarizing evidence on how airborne MPs are emitted, transported, transformed, and inhaled.
Addressing the importance of microplastic particles as vectors for long-range transport of chemical contaminants: perspective in relation to prioritizing research and regulatory actions
This perspective examined the role of microplastic particles as vectors for long-range environmental transport of persistent organic pollutants (POPs), concluding that while microplastics can adsorb and carry chemical contaminants, their relative contribution to POP transport compared to other pathways requires further investigation before regulatory prioritization.
Microplastic in the Air
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.
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.
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.
Degradation of Microplastics and Nanoplastics: An Underexplored Pathway Contributing to Atmospheric Pollutants
Researchers reviewed how microplastics and nanoplastics degrade in the atmosphere through mechanical, photochemical, and microbial processes, releasing gaseous byproducts and serving as carriers for toxic substances. The study found that atmospheric degradation increases the particles' ability to interact with pollutants like heavy metals and persistent organic chemicals, amplifying health risks. Evidence indicates that airborne microplastics may also influence climate by affecting cloud formation and releasing greenhouse gases during photodegradation.

Atmospheric microplastics: exposure, toxicity, and detrimental health effects
This review summarizes what is known about microplastics in the air, including their sources, how they travel, and their effects on human health when inhaled or swallowed.
