Atmospheric transport and deposition of microplastics in a remote mountain catchment

An Author Correction to this article was published on 18 June 2019

This article has been updated


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 over five months, that represent atmospheric wet and dry deposition and identified fibres up to ~750 µm long and fragments ≤300 µm as microplastics. We document relative daily counts of 249 fragments, 73 films and 44 fibres per square metre that deposited on the catchment. An air mass trajectory analysis shows microplastic transport through the atmosphere over a distance of up to 95 km. We suggest that microplastics can reach and affect remote, sparsely inhabited areas through atmospheric transport.

    In the version of this Article originally published, the following text was missing from the Acknowlegements: ‘CESBIO OHM Bernadouze weather station is supported by the Observatoire Spatial Régional (CNRS-INSU) and CNES-TOSCA funding was awarded to S. Gascoin. This scientific work was made possible with the logistical support of the ONF (French National Forestry Office) and the support of the inhabitants of the valley.’ In addition, ref. 17 was the wrong reference, it should have been ‘Gascoin, S. & Fanise, P. Bernadouze Meteorological Data (SEDOO OMP, 2018)’. The Article has now been corrected.
