The emerging threat of atmospheric microplastic pollution has prompted researchers to study areas previously considered beyond the reach of plastic. Investigating the range of atmospheric microplastic transport is key to understanding the global extent of this problem. While atmospheric microplastics have been discovered in the planetary boundary layer, their occurrence in the free troposphere is relatively unexplored. Confronting this is important because their presence in the free troposphere… 

Macro- and Microplastics in the Antarctic Environment: Ongoing Assessment and Perspectives

The number of scientists and tourists visiting Antarctica is on the rise and, despite the management framework for environmental protection, some coastal areas, particularly in the Antarctic

Microplastics and nanoplastics in the marine-atmosphere environment

The discovery of atmospheric micro(nano)plastic transport and ocean–atmosphere exchange points to a highly complex marine plastic cycle, with negative implications for human and ecosystem health.

Effect of Aerosol Vertical Distribution on the Modeling of Solar Radiation

Default aerosol extinction coefficient profiles are commonly used instead of measured profiles in radiative transfer modeling, increasing the uncertainties in the simulations. The present study aimed



Atmospheric transport is 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, we

Atmospheric transport and deposition of microplastics in a remote mountain catchment

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

Consistent transport of terrestrial microplastics to the ocean through atmosphere.

Observations provide field-based evidence that suspended atmospheric microplastics are an important source of microplastic pollution in the ocean, especially the pollution caused by textile microfibers.

Evidence of a long‐term increase in tropospheric ozone from Pic du Midi data series: Consequences: Positive radiative forcing

The rate at which ozone is increasing in the troposphere is uncertain due to the lack of accurate long-term measurements. Old ozone measurements obtained at the Pic du Midi Observatory (3000 m high,

Examination of the ocean as a source for atmospheric microplastics

First evidence of MP particles are shown in marine boundary layer air samples on the French Atlantic coast during both onshore and offshore winds, indicating a potential for MPs to be released from the marine environment into the atmosphere by sea-spray giving a globally extrapolated figure of 136000 ton/yr blowing on shore.

Asian dust transported one full circuit around the globe

Mineral dust is usually transported long distances in the lower troposphere. There are examples of Asian dust being transported across the Pacific Ocean 1‐7 , and traces of Asian dust have also been

Observations of Thermally Driven Circulations in the Pyrenees: Comparison of Detection Methods and Impact on Atmospheric Composition Measured at a Mountaintop

The atmospheric composition measured at the Pic du Midi high-altitude observatory (2875 m MSL) in the French Pyrenees is frequently affected by upward transport of boundary layer air during anabatic

White and wonderful? Microplastics prevail in snow from the Alps to the Arctic

The authors detect microplastics in European and Arctic snow, highlighting the importance of atmospheric transport as a pathway for MPs and highlighting that atmospheric transport and deposition can be notable pathways for MPs meriting more research.
