Plastic litter is an ever-increasing global issue and one of this generation’s key environmental challenges. Microplastics have reached oceans via river transport on a global scale. With the exception of two megacities, Paris (France) and Dongguan (China), there is a lack of information on atmospheric microplastic deposition or transport. Here we present the observations of atmospheric microplastic deposition in a remote, pristine mountain catchment (French Pyrenees). We analysed samples, taken… Expand

As an issue of great concern, microplastics pollution has emerged as a key environmental challenge of our time. The atmosphere is a significant compartment in the global cycle of microplastics,Expand
Atmospheric transport is a major pathway of microplastics to remote regions
TLDR
It is shown that atmospheric transport is a major pathway for road plastic pollution over remote regions, and it is suggested that the Arctic may be a particularly sensitive receptor region, where the light-absorbing properties of TWPs and BWPs may also cause accelerated warming and melting of the cryosphere.

Atmospheric Transport, a Major Pathway of Microplastics to Remote Regions
In recent years, marine, freshwater and terrestrial pollution with microplastics has been discussed extensively, whereas atmospheric microplastic transport has been largely overlooked. Here, weExpand
The abundance and characteristics of atmospheric microplastic deposition in the northwestern South China Sea in the fall
Abstract Atmospheric microplastics have been widely reported and detected in remote mountain areas and oceans, indicating that they can be transported over long distances through the atmosphere.Expand
Atmospheric microplastic deposition in an urban environment and an evaluation of transport
Microplastics are a global environmental issue contaminating aquatic and terrestrial environments. They have been reported in atmospheric deposition, and indoor and outdoor air, raising concern forExpand
Modelling Microplastics in the River Thames: Sources, Sinks and Policy Implications
With widespread, long-term historical use of plastics and the presence of microplastics in a range of new and existing products, there is rising concern about their potential impacts on freshwaterExpand
Atmospheric microplastics: A review on current status and perspectives
Abstract Microplastics have recently been detected in the atmosphere of urban, suburban, and even remote areas far away from source regions of microplastics, suggesting the potential long-distanceExpand
Importance of atmospheric transport for microplastics deposited in remote areas.
TLDR
Following this first evidence of atmospheric microplastic deposition in a pristine location, it is necessary to reconsider previous studies on atmospheric microPlastic deposition and behavior in remote areas. Expand
Temporal and spatial variations of microplastics in roadside dust from rural and urban Victoria, Australia: Implications for diffuse pollution.
TLDR
Monitoring roadside dust can be considered as an initial and cost-effective screening of microplastic pollution in urban areas and prolonged sampling schemes for roadside dust monitoring are advocated. Expand
Occurrence and transport of microplastics sampled within and above the planetary boundary layer.
TLDR
This pioneer study is the first evidence of the microplastic presence above PBL and their potential long-range transport from their point of release even crossing distant borders. Expand

Microplastic contamination of the oceans is one of the world’s most pressing environmental concerns. The terrestrial component of the global microplastic budget is not well understood becauseExpand
Characteristic of microplastics in the atmospheric fallout from Dongguan city, China: preliminary research and first evidence
TLDR
Dust emission and deposition between atmosphere, land surface, and aquatic environment were associated with the transportation of microplastics, and adhering particles, grooves, pits, fractures, and flakes were the common patterns of degradation. Expand
The effect of dams on river transport of microplastic pollution.
TLDR
The results show that the sediment collecting behind dams is one sink for microplastics in river systems at long timescales, indicating that accounting for dams may be important when modeling global riverine microplastic transport. Expand
Microplastic pollution of lakeshore sediments from remote lakes in Tibet plateau, China.
TLDR
The presence of microplastics even for inland lakes in remote areas under very low human impact is demonstrated, and microplastic pollution can be a global issue. Expand
Synthetic fibers in atmospheric fallout: A source of microplastics in the environment?
TLDR
The atmospheric fallout of microplastics was investigated in two different urban and sub-urban sites and a rough estimation was shown showing that between 3 and 10 tons of fibers are deposited by atmospheric fallout at the scale of the Parisian agglomeration every year. Expand
Microplastics in Swiss Floodplain Soils.
TLDR
The wide distribution of MPs, their presence in remote unsettled high mountain areas, decoupling of MEP and MP compositions, and the dominance of MPs by small (<500 μm diameter) particles, indicate that MPs enter soils via diffuse aeolian transport. Expand

TLDR
This review highlights recent findings and discusses open questions, focusing on the methodology of assessing this contaminant in freshwater ecosystems, including sampling strategies, sample treatment, and reliable analytical methods to identify microplastics. Expand

Arctic sea ice is an important temporal sink and means of transport for microplastic
TLDR
It is shown that MPs in sea-ice have no uniform polymer composition and that, depending on the growth region and drift paths of the sea ice, unique MP patterns can be observed in different sea ice horizons. Expand
Abundance, size and polymer composition of marine microplastics ≥10μm in the Atlantic Ocean and their modelled vertical distribution.
TLDR
It is concluded that small microplastic is ubiquitously distributed over the ocean surface layer and has a lower residence time than larger plastic debris in this compartment. Expand
