| Microplastic pollution is a global environmental issue. Most MP studies have focused on aquatic systems and a few studies have confirmed the presence of MPs in indoor and outdoor air. Although atmospheric transport and fall-out can be important mechanism in the global distribution of MPs, there exists little information on their occurrence and transport in air. We investigated the occurrence and seasonal change of MPs in air. For that, we collected atmospheric fall-out samples (including dry and wet deposition) periodically every two weeks (or one month) throughout one year from April 2017 to May 2018 at two stations. Sampling stations consist of Daecheong Island and Incheon city, representing a remote area and coastal urban area, respectively. Our preliminary results showed the occurrence of various MPs including fiberous, fragmented and spherical MPs. In the present study, we compare atmospheric deposition flux of MPs between two stations, and confirm the atmospheric transport of MPs. |
