Comment on egusphere-2025-1821
This peer review comment on an atmospheric microplastics study characterizes source profiles and emission factors for eight polymer types and three plasticizer classes from plastic burning, fruit bag burning, road traffic, agricultural film, and livestock breeding sources.
Comment on egusphere-2025-1821
This comment discusses a study characterizing source profiles for atmospheric microplastics, including particles from plastic burning, fruit waste degradation, and other common sources, offering guidance for distinguishing emission sources in ambient air monitoring.
Comment on egusphere-2023-1025
This comment discusses a study on atmospheric transport of microplastic particulate matter, noting that long-range atmospheric dispersal means microplastics reach virtually every environment on Earth, including remote areas far from human settlements. Understanding atmospheric transport mechanisms is key to modeling global microplastic deposition.
Comment on egusphere-2023-1025
This comment paper examines the atmospheric transport of microplastics as particulate matter, comparing it to the well-studied transport of mineral dust. Understanding how air currents carry microplastics to remote environments helps explain their ubiquitous presence even in pristine ecosystems far from human activity.
Comment on egusphere-2025-605
Researchers examined the atmospheric transport of microplastics, focusing on how their settling behavior — determined by physical properties including size and shape — governs the dispersion of large microplastic particles through the atmosphere and their deposition across environments.
Comment on egusphere-2023-1025
This comment discusses a study on atmospheric transport of microplastics, noting that the mechanisms that move microplastics through the air differ importantly from those for mineral dust. Better understanding these transport pathways is essential for accurately predicting where airborne microplastics deposit globally.
Atmospheric microplastic emissions from land and ocean
Researchers compiled a comprehensive atmospheric microplastic dataset and derived top-down and bottom-up emission estimates for particles in the 5-100 micrometer size range from both land and ocean sources, providing gridded emissions data in multiple formats for use in atmospheric transport modelling.
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.
Comment on egusphere-2025-1575
Researchers developed a representation of airborne microplastics within the UK Earth System Model (UKESM1.1), adding both fragment and fibre types across multiple aerosol size modes that interact with existing deposition and ageing processes. Simulated microplastics showed higher concentrations over land but were transported to remote regions including Antarctica, highlighting their potential air quality and climate relevance.
Comment on egusphere-2025-1575
This review examines a global climate model implementation of airborne microplastics as an atmospheric aerosol species, addressing their absence from current climate models despite recognized air quality and climate impacts. The comment evaluates the modeling approach for representing microplastic transport, deposition, and radiative effects in the atmosphere.
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 microplastic emissions from land and ocean
Researchers quantified atmospheric microplastic emissions from both land and ocean surfaces, finding that re-suspension of deposited plastics from land and sea spray from the ocean are significant sources of airborne particles. The results highlight that the ocean is not just a sink but also a source of airborne microplastics.
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.

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.
