Importance of atmospheric transport for microplastics deposited in remote areas

Atmospheric transport is an important pathway for the deposition of micro- and nano-plastics in remote areas. However, the sources and fate of atmospheric microplastics remain poorly understood. A study on atmospheric transport and deposition in the Pyrenean Mountains highlights the movement of microplastics away from known sources (cities, agriculture, and industry) into remote areas. 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. • Atmospheric transport is an important pathway for microplastics deposition. • Atmospheric microplastics can be identified in the remote area. • Implications for research in the Tibetan Plateau are discussed.
