"A Study on the Reduction of Marine Microplastics - Focus on Environmental Governance -"
AI summary Read the abstract
This Korean study analyzed marine debris monitoring data from 2016 to 2020 to understand the distribution and growth of marine litter, particularly microplastics, in Korean coastal waters. Total debris collected more than doubled over the period, with most found on coastlines rather than in the water column. The authors recommend expanding monitoring to subsurface water and refining governance approaches.
This study focused on environmental governance to reduce marine micro plastics. In the last 5 years, marine debris was generated in the order of coast > sedimentation > floating debris. In addition, 70,840 tons of marine debris was collected in 2016, but it is increasing to 138,362 tons in 2020. Currently, marine debris monitoring research is being conducted mainly on the coast of Korea, but since microplastics can affect marine life and items produced on the coast, we suggest diversifying monitoring. And the measures to reduce styrofoam buoy waste are as follows. Introduce a systematic and sustainable education system that can make fishery workers aware of the problem of waste dumped into the sea and the seriousness of marine pollution.

Proposing Policy for the Prevention of Marine Pollution from Microplastics
AI summary Read the abstract
This Korean policy paper reviews current international and domestic regulations on microplastics and proposes stronger policies for preventing marine pollution, including regulatory expansion, systematic monitoring, and public education. South Korea's coastal microplastic contamination levels are identified as significantly higher than those of other countries, necessitating stronger action.
Abundance and Distribution Characteristics of Microplastics in Surface Seawaters of the Incheon/Kyeonggi Coastal Region
AI summary Read the abstract
Researchers investigated microplastics in both the surface microlayer and subsurface waters of the Incheon/Kyeonggi coastal region of Korea, finding that microplastic concentrations were significantly higher in the surface microlayer than in bulk seawater. Fragment and fiber morphologies dominated, with the distribution patterns reflecting urban runoff and shipping activity as likely sources.
Spatial distribution of microplastic in the surface waters along the coast of Korea
AI summary Read the abstract
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.
Development of Analytical Method for Microplastics in Seawater
AI summary Read the abstract
This Korean study develops standardized analytical methods for detecting and quantifying microplastics in seawater, including protocols for sampling surface microlayer and subsurface water separately. The research establishes methodological baselines for monitoring microplastic distribution in Korean coastal waters.
Regulation of Marine Pollution by Microplastics with a Focus on Normative Approach under the International Law
AI summary Read the abstract
This Korean legal analysis examines international law frameworks for regulating ocean microplastic pollution, identifying gaps and challenges in current legal instruments. The author argues that microplastics present unique regulatory challenges that require new or strengthened international governance approaches.
