ClearMicroplastics in the Taiwan Strait and adjacent sea: Spatial variations and lateral transport
Researchers sampled microplastics from both surface water and seafloor sediments across the Taiwan Strait and surrounding seas, finding average concentrations of 174 particles per cubic meter in water and 121 particles per kilogram in sediment. Polyester and rayon fibers dominated, pointing to domestic wastewater and the synthetic textile industry as primary sources. The study helps map microplastic distribution in a heavily trafficked and economically important sea corridor, where currents spread contamination across national boundaries.
Microplastics in seawater and two sides of the Taiwan Strait: Reflection of the social-economic development
Researchers surveyed microplastic abundance in surface seawater and coastal sediments on both sides of the Taiwan Strait, finding differences in contamination levels that reflected contrasting levels of industrialization and urban development on the Chinese mainland versus Taiwan sides.
Marine microplastics in the surface waters of “pristine” Kuroshio
Researchers found microplastic concentrations in Taiwan's coastal waters and the Kuroshio current averaging 0.05 items/m³, with polypropylene and polyethylene dominating, and identified hotspots suggesting rivers and local currents transport plastics into the North Pacific Gyre.
Taking a mass-balance approach to assess marine plastics in the South China Sea
Researchers applied a mass-balance modeling approach to assess marine plastic pollution in the South China Sea, finding critical data gaps on plastic inputs, transfer rates, and sink terms that prevent accurate quantification of this recognized global plastic hotspot.
Microplastic pollution of the Tamsui River and its tributaries in northern Taiwan: Spatial heterogeneity and correlation with precipitation
Researchers investigated microplastic pollution in the Tamsui River and its tributaries in northern Taiwan, collecting samples over three months. They found microplastics in every sample, with concentrations varying widely between rivers, from 2.5 to 83.7 particles per cubic meter. The study found a positive correlation between rainfall and microplastic abundance, suggesting that precipitation washes plastic debris from land into waterways.
Tide-driven microplastics transport in an elongated semi-closed bay: A case study in Xiangshan Bay, China
Researchers combined field sampling and numerical tidal flow modeling to study microplastic transport in Xiangshan Bay, China, finding that tidal currents play a significant role in redistributing microplastics within this semi-closed coastal bay before they reach the open ocean.
Transport mechanism of microplastics from a still water system to a dynamic estuarine system: A case study in Macao SAR
A study in Macao's Pearl River Estuary traced microplastics from still-water ecosystems into the dynamic estuarine system, revealing how hydrodynamic forces transport microplastics from inland reservoirs and ponds to coastal waters and ultimately the South China Sea.
Study of marine debris around a tourist city in East China: Implication for waste management
Marine debris was surveyed in a coastal tourist city in eastern China, revealing patterns driven by tourism, fishing, and poor waste management. The study argues that effective debris management requires understanding local sources, which differ significantly between developed and developing regions.
A perspective study on occurance, impacts and sources of microplastics in the marine environment of south China Sea and Gulf of Thailand
A synthesis of published data on microplastics in the South China Sea and Gulf of Thailand identified the Pearl River and Mekong River as major plastic inputs, with the Gulf of Thailand showing medium plastic abundance levels, and called for improved management strategies for these sensitive regions.
Characteristics and patterns of marine debris in the Chinese beach-sea continuum
Researchers analyzed a 10-year time-series dataset (2012-2021) of marine debris from Chinese beaches and adjacent seas to examine characteristics of debris distribution across the beach-sea continuum. The study investigated the quantitative relationships between debris density and accumulation patterns in coastal and marine zones, finding that floating debris is transported bidirectionally between sea and coast through various oceanographic and meteorological processes.
Simulation of seasonal transport of microplastics and influencing factors inthe China Seas based on the ROMS model
Researchers used the Regional Ocean Modeling System combined with the LTRANS Lagrangian transport model to simulate seasonal microplastic transport throughout the China Seas, finding that circulation patterns, river discharge, and particle properties drive marked seasonal variations in microplastic pathways and spatial distribution.
A critical review on the sources and instruments of marine microplastics and prospects on the relevant management in China
This critical review examined sources, distribution, and monitoring instruments for marine microplastics in China, identifying key knowledge gaps and proposing management strategies to address the country's significant contribution to global ocean plastic pollution.
Can microplastics in offshore waters reflect plastic emissions from coastal regions?
Researchers found a significant negative correlation between coastal plastic discharge amounts and offshore microplastic abundance in Chinese waters, indicating that hydrodynamic conditions rather than proximity to pollution sources primarily determine microplastic distribution.
Microplastics in the surface waters of the South China sea and the western Pacific Ocean: Different size classes reflecting various sources and transport
Researchers investigated microplastic distribution in the South China Sea and western Pacific Ocean, finding that different size classes reflect distinct sources and transport mechanisms, with higher concentrations in the northern South China Sea linked to riverine inputs.
Microplastics in the western Pacific and South China Sea: Spatial variations reveal the impact of Kuroshio intrusion
Surface microplastic distribution in the western Pacific and South China Sea was strongly influenced by Kuroshio Current intrusion, with stations affected by Kuroshio showing distinct polymer composition and concentration patterns from those outside its influence, demonstrating that major western boundary currents redistribute microplastics across ocean basin scales.
