Abstract

Marine pollution of microplastics (plastics less than 5 mm) is attracting worldwide attention. In this study, the maximum number of MPs in the seabed was 97.2 / kg-dry. It was found that the number was high near the estuary and low offshore. The polymer was spatially different. It was confirmed that the number of MPs and the polymer changed with time at all the survey points. This suggests that there may be multiple sedimentary processes in this area.
