The study demonstrates that moss-based monitoring is a practical, low-cost method for tracking airborne microplastic pollution in cities.

A preliminary comparison of microplastic type, size, and composition in atmospheric and foliage samples in an urban scenario
Researchers compared microplastic types, sizes, and polymer compositions in atmospheric dry and wet deposition at multiple sites, assessing contributions to ecosystem contamination. The results showed that atmospheric deposition is a significant pathway for microplastic redistribution, particularly to remote areas.
Potential Role of Mosses in Evaluating Airborne Microplastic Deposition in Terrestrial Ecosystems
This review examines the potential of mosses to serve as cost-effective biomonitors for tracking airborne microplastic deposition in terrestrial ecosystems. Preliminary studies indicate that mosses accumulate higher concentrations of microplastics than lichens, likely due to their physical structure. The study outlines steps needed to develop a standardized, reliable methodology for using mosses to monitor airborne microplastic pollution across both inhabited and remote regions.
Forest soils accumulate microplastics through atmospheric deposition
Researchers quantified microplastics in forest soil layers and atmospheric throughfall deposition to understand how microplastics accumulate in forest ecosystems. They found that microplastics initially enriched in decomposed litter layers before accumulating in deeper mineral soil through natural litter turnover processes. The study suggests that forests act as good indicators of atmospheric microplastic pollution, with most forest soil microplastics originating from atmospheric deposition rather than other sources.

A five-year (2019–2023) monitoring study in a valley city found rising atmospheric microplastic deposition, with summer peaks over four times higher than winter lows, strongly influenced by precipitation, wind, temperature, and urban activity levels. Long-term data showing increasing airborne microplastic trends have direct implications for inhalation exposure in urban populations.

Vehicle density and the textile industry were identified as primary drivers, and experiments showed that deposited microplastics altered moss bacterial communities, suggesting ecological impacts on wetland ecosystems.
Peatlands as geo-archives for atmospheric micro- and nano-plastics: a perspective review
This review explores the potential of peatlands, the most widespread type of wetlands on Earth, to serve as natural archives for tracking historical atmospheric deposition of micro- and nanoplastics.

The study evaluates various sampling and analytical methods to guide future research on reconstructing plastic pollution timelines from peatland cores.
