ClearSources and Circulation of Microplastics in the Aerosphere – Atmospheric Transport of Microplastics
This review examines sources, transport mechanisms, and deposition patterns of airborne microplastics in the atmosphere, finding that factors like wind, temperature, rainfall, population density, and human activities influence their abundance and long-distance dispersal.
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. The authors identify deposition via precipitation as a major pathway by which atmospheric microplastics contaminate soil and water surfaces.
Atmospheric deposition of microplastics in the coastal zone: Characteristics and relationship with meteorological factors
Microplastics deposited from the atmosphere were sampled and characterized in a coastal zone, with analysis of meteorological factors including air humidity, wind speed, precipitation, and air mass trajectories. The study found measurable atmospheric microplastic deposition in the coastal environment, with weather patterns influencing deposition rates and particle characteristics.
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 Microplastics: Inputs and Outputs
Researchers examined how microplastics enter and move through the atmosphere, finding that up to 8.6 megatons per year may be suspended in air above the oceans alone. The particles are launched into the air from ocean spray and land-based sources, then distributed by wind before returning to Earth through rain and dry deposition. The study highlights that atmospheric transport is a major pathway for spreading microplastic contamination to even the most remote regions of the planet.
Dynamics of airborne microplastics, appraisal and distributional behaviour in atmosphere; a review
This review explores the sources, distribution, and behaviour of airborne microplastics in the terrestrial environment. Researchers summarize how factors like size, density, and atmospheric conditions influence microplastic transport and concentration in air. The study highlights that airborne exposure represents a significant and relatively understudied route of human microplastic intake, with particles capable of carrying organic pollutants that bioaccumulate through food webs.
Microplastics ride the atmosphere
Research confirms that microplastic particles are transported through the atmosphere over long distances, depositing in remote areas including the Arctic and high mountains. Atmospheric transport is now recognized as a major pathway spreading microplastic contamination to virtually every part of the planet.
Is atmospheric pathway a significant contributor to microplastics in the marine environment?
Researchers reviewed evidence for atmospheric transport of microplastics to and from marine environments, finding that wind-driven processes like sand storms, bubble bursts, and sea spray can eject microplastics from ocean surfaces into aerosols, making the atmosphere a significant but understudied pathway in the marine microplastic cycle.
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.
Physical characteristics of microplastic particles and potential for global atmospheric transport: A meta-analysis
This meta-analysis pools data from multiple studies to examine the physical characteristics of airborne microplastics and how they travel through the atmosphere. The findings confirm that microplastics can be transported globally by wind, meaning people everywhere are breathing in these particles regardless of how far they live from pollution sources.
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.
Evaluating Ecological Impacts and Atmospheric Fate of Microplastics: Ecological Perspectives and Challenges
Researchers review how microplastics spread through the atmosphere via wind and weather before settling into water bodies, soil, and plant life — creating pathways for human exposure through the food chain. The study highlights gaps in analytical methods and calls for standardized, accurate measurement techniques to better understand and address the full ecological threat of airborne microplastic pollution.

Quick analysis of the influence of the monsoon on the concentration of microplastics in the air
Researchers analysed how monsoon rainfall affected atmospheric microplastic concentrations, finding that precipitation events redistributed plastic particles and temporarily increased concentrations of certain polymer types in air samples. The study identifies rainwater as both a carrier and a concentrating medium for atmospheric microplastics.
A mechanistic approach to evaluating atmospheric deposition of micro- and nanoplastic particles
This study developed a theoretical framework to better understand how microplastic and nanoplastic particles move through the atmosphere and deposit onto land and water surfaces via wet and dry deposition. By drawing on knowledge from how other aerosols like mineral dust behave, the researchers identified key physical processes — including particle size, shape, and density — that govern how far microplastics travel and where they land. The work is important for modeling the global spread of microplastic pollution, including to remote regions far from pollution sources.
Atmospheric microplastic deposition in an urban environment and an evaluation of transport
Researchers measured microplastic deposition in central London and found contamination in all samples, with rates ranging from 575 to 1,008 particles per square meter per day. Fibrous microplastics made up 92% of the particles, and 15 different polymer types were identified. Wind analysis revealed different source areas for fibrous and non-fibrous airborne microplastics, providing the first evidence that the atmosphere is a significant pathway for microplastic pollution in urban areas.

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.
