Measurement and distribution of airborne microplastics: A review of their impact on pollutant transport
AI summary Read the abstract
Researchers reviewed how airborne microplastics act as transport vehicles for heavy metals, volatile organic compounds, and other pollutants, finding that their large surface area and hydrophobic nature enable long-distance contamination spread through the atmosphere, amplifying environmental and health risks beyond what microplastics cause alone.
This review paper provides a comprehensive analysis of the measurement and distribution of microplastics in the atmosphere and their role in the adsorption and transport of organic and inorganic pollutants. Due to their small size, large surface area, and hydrophobic nature, microplastics can adsorb a wide range of pollutants, including volatile organic compounds (VOCs) and heavy metals. These pollutants, strongly bound to the surface of microplastics, can remain suspended in the atmosphere for extended periods, facilitating the widespread distribution of contaminants. Building on existing research, this paper systematically reviews the sampling, pretreatment, and analytical methodologies applied to study microplastics in the air. Furthermore, it examines the influence of environmental factors on the adsorption and desorption dynamics of pollutants associated with microplastics. Various studies indicate that microplastics can interact with pollutants such as heavy metals, organic compounds, and microorganisms to form complex contaminants. These complexes can be transported and redistributed across long distances in the atmosphere, amplifying their environmental and health impacts. This review highlights that microplastics are not merely a pollutant themselves but serve as a vehicle for the migration and dispersion of other contaminants. This dual role emphasizes the significant risks microplastics pose to public health and the environment, necessitating further research and effective mitigation strategies.

Microplastics in ambient air: a review of atmospheric abundance, human exposure and urgent research needs
AI summary Read the abstract
This review pulled together findings from 84 studies to show that tiny plastic bits called microplastics are floating in the air everywhere, indoors, outdoors, in cities, and even in remote places like Antarctica, with tiny plastic fibers being the most common type found. Since we're breathing this stuff in daily, early research links it to lung inflammation, cell damage, and metabolic problems, though scientists say we still need more studies to understand exactly how much exposure is harmful and over what timeframe.

Researchers reviewed how microplastics become airborne, travel long distances through the atmosphere, and eventually deposit in remote environments far from their source — suggesting that no ecosystem on Earth, including pristine wilderness, is fully protected from plastic pollution.
Long-distance atmospheric transport of microplastic fibres influenced by their shapes
AI summary Read the abstract
A new settling velocity model accounting for the actual flat shapes of microplastic fibers found that flat fibers have atmospheric residence times more than 450% longer than cylindrical equivalents, enabling far greater long-distance transport than previously estimated. This means microplastic fiber pollution is dispersed globally through the atmosphere far more efficiently than models assumed, reaching remote ecosystems and contributing to human inhalation exposure everywhere on Earth.
