Micro- (1 to 5000 microns) and nanoplastics (< 1 micron) are one of the most pressing environmental issues of our time. These tiny plastic particles have been found virtually in all ecosystems including land, ocean, river, lake, and even sea ice. Recently, atmosphere has emerged as an important pathway for these particles.

Using laboratory and field experiments as well as atmospheric models, we study emission, atmospheric transport, and deposition of micro- and nanoplastics in the environment.
