Summary

Scientists surveyed microplastics (0.33–5 mm) across six semi-enclosed bays and two open coastal waters in Korea during July surveys from 2015 to 2017, finding mean abundances of 1.12–4.74 particles per m2 with expanded polystyrene and paint particles as dominant types.

We examined the spatial distribution and local characteristics of microplastics (0.33-5 mm) in surface water from six semi-enclosed bays and two coastal waters in Korea. Surveys were conducted in July from 2015 to 2017 using a Manta trawl. The mean abundance of total microplastics ranged from 1.12-4.74 particles/m among sites; the microplastics were mostly expanded polystyrene (EPS), paint particles, fragments and fibers. The mean microplastic abundance (2.85 particles/m) in urban areas was about 1.5 times higher than in rural areas (1.86 particles/m) (p < 0.05). EPS dominated at rural sites, while fragments, paint particles, and fibers were relatively more dominant in urban areas. The different types and quantities of microplastic particles indicated that the region-specific occurrence of microplastics is likely to be related to differences in human activities between urban and rural areas, even though fibers were distributed throughout the study area.
