The Hidden Cost of Buoyancy: Environmental and Social Consequences of EPS in Marine Aquaculture
AI summary Read the abstract
Researchers examined how expanded polystyrene buoys used in South Korean oyster aquaculture generate microplastic contamination that bioaccumulates in filter-feeding organisms and disproportionately burdens low-income coastal communities, advocating for biodegradable buoy alternatives and systemic governance reforms in marine infrastructure.
Plastic buoy pollution, particularly from expanded polystyrene (EPS), has emerged as a major environmental threat, impacting marine ecosystems, aquaculture, and human health. This study examines microplastic contamination from EPS buoys, focusing on South Korea’s oyster farms in Tongyeong and Jeju Island’s coastal economy. It highlights bioaccumulation in filter-feeding organisms, disruptions to biodiversity, and the disproportionate burden placed on low-income communities. Institutional inertia and inadequate waste management systems hinder reform, necessitating a transition to biodegradable alternatives. By proposing an eco-friendly buoy design, this research advocates for systemic change in marine infrastructure, governance, and sustainable seafood production.

Spatial distribution and historical trend of microplastic pollution in sediments from enclosed bays of South Korea
AI summary Read the abstract
Researchers analyzed microplastic pollution in seafloor sediments from enclosed bays in South Korea, comparing urban, aquaculture, and conservation sites. Urban areas showed the highest contamination with the most diverse polymer types, while aquaculture sites were dominated by expanded polystyrene from fishing equipment. Analysis of sediment cores revealed that microplastic pollution has been steadily increasing over time, with historical trends correlating to industrialization patterns.
