ClearAtmospheric chemistry of microplastics:T ransport, environmental impacts, and governance.
This article reviews the atmospheric chemistry of microplastics, examining their sources, transport mechanisms, environmental impacts including as carriers of heavy metals and persistent organic pollutants, and current remediation and governance strategies.
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.
A Review of Atmospheric Micro/Nanoplastics: Insights into Source and Fate for Modelling Studies
This review synthesizes current knowledge about how micro- and nanoplastics move through the atmosphere, covering their sources, transport mechanisms, and eventual deposition. Researchers found that atmospheric transport can carry these particles over long distances quickly, making it a major pathway for global plastic pollution spread. The study identifies key knowledge gaps needed for developing accurate models of airborne microplastic behavior.
Various Perspectives on Occurrence, Sources, Measurement Techniques, Transport, and Insights Into Future Scope for Research of Atmospheric Microplastics

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 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.
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.
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.
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.
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.
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.
Distribution and transport of atmospheric microplastics and the environmental impacts: A review
This review examines the distribution, transport, and environmental impacts of atmospheric microplastics, synthesizing evidence that airborne plastics are found globally from urban centers to remote polar regions.

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.
