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.
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.
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.
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-2025-605
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.
Insight into the size-resolved markers and eco-health significance of microplastics from typical sources in northwest China
Researchers characterized atmospheric microplastics emitted from five source types — plastic burning, fruit bag burning, road traffic, agricultural film, and livestock breeding — in northwest China's Guanzhong Plain, finding distinct polymer and plasticizer profiles for each source. Plastic burning produced the highest diversity of polymer types, providing source-specific fingerprints useful for pollution management.
Constraining the atmospheric limb of the plastic cycle
Researchers modeled the atmospheric transport of microplastics across the western United States and found that most airborne particles originate from the breakdown of legacy plastic waste that has accumulated in the environment. Roads were identified as the dominant source, followed by marine, agricultural, and dust emissions near population centers. The study suggests that atmospheric microplastic transport represents a significant and underappreciated component of the global plastic pollution cycle.
Microplastics in the Atmosphere: A Global Perspective
This global modeling study found that atmospheric microplastic sources are dominated by land-based transport rather than ocean emissions, challenging earlier assumptions and suggesting that road traffic and other terrestrial activities are the primary drivers of microplastic particle distribution in the atmosphere.

Researchers characterized microplastic source profiles and plasticizer emissions (phthalates, benzothiazoles, bisphenol A) from five pollution sources (plastic burning, traffic, agricultural film, livestock) in PM2.5 and PM10 aerosols across the Guanzhong Plain in northern China, providing source-resolved atmospheric microplastic data.
Deposition of Roadside Atmospheric Non-Tire Wear Microplastics: Characteristics and Influencing Factors
A year-long roadside study measured the atmospheric deposition of microplastics in two size fractions, finding deposition rates of 3–9 million particles per hectare per month for larger particles and identifying polymers including PP, PE, PS, PVC, PET, and nylon. Traffic was the dominant source of larger particles near the road, while wind patterns dispersed smaller particles more broadly from industrial sources. Roads are a major but underappreciated source of airborne microplastic deposition into surrounding soils and waterways, and this study quantifies that contribution with new precision.
Global emission, atmospheric transport and deposition trends of microplastics originating from road traffic
This modeling study estimated global emissions, atmospheric transport, and deposition of microplastics from road traffic sources, finding that road-derived microplastics are transported long distances by wind and deposited in remote locations including the Arctic. The findings quantify roads as a globally important source of atmospheric microplastic pollution.
