ClearA Systematic Review on Microplastic Contamination in Fishes of Asia: Polymeric Risk Assessment and Future Prospectives
This systematic review found widespread microplastic contamination in freshwater and saltwater fish across Asia, with polyethylene and polypropylene being the most common plastic types. Since fish is a major protein source for billions of people, this contamination represents a direct pathway for microplastics to enter the human diet.
A systematic review on microplastic contamination in marine Crustacea and Mollusca of Asia: Current scenario, concentration, characterization, polymeric risk assessment, and future Prospectives
This systematic review documented microplastic contamination in shellfish and crustaceans across Asia, finding 79 species affected. Since these seafood species are widely consumed, the presence of microplastics — especially polyethylene and polypropylene — in their tissues represents a direct route of human exposure through diet.
Distribution and environmental risk assessment of microplastics in continental shelf sediments in the southern East China Sea: A high-spatial-resolution survey
Researchers conducted a high-spatial-resolution survey of microplastics in surface sediments across the southern East China Sea continental shelf, finding omnipresent contamination dominated by polyethylene fibers and fragments, with concentrations elevated near urban coastal areas.

This review assessed microplastic contamination in coastal waters across Southeast Asia, synthesizing monitoring data to identify pollution hot spots, dominant polymer types, and the implications for regional marine ecosystem health.
Microplastic Accumulation in Hong Kong’s Marine Sediment: Spatial Pattern and Potential Sources
Researchers conducted a comprehensive survey of microplastics in marine sediments across Hong Kong's waters. They found microplastics at every sampling site, with fibers and fragments being the most common forms and polypropylene and polyethylene the dominant plastics. The spatial patterns suggest that coastal urbanization and water circulation are key factors driving where microplastics accumulate in sediments.
Microplastics in Freshwater Environment in Asia: A Systematic Scientific Review
This systematic review summarizes existing research on microplastic contamination in Asian freshwater environments, including rivers, lakes, and reservoirs. The study found that microplastics are widespread in Asian freshwater systems, with research concentrated in China and Southeast Asia, and identified potential risks to both aquatic life and human health. Since billions of people in Asia rely on freshwater for drinking and food production, this contamination is a significant public health concern.
Microplastics in Asian rivers: Geographical distribution, most detected types, and inconsistency in methodologies
A systematic review of 228 studies on microplastics in Asian rivers found polyethylene, polypropylene, and PET as the dominant polymers, primarily as fibers and fragments, with research concentrated in China and Japan. The diversity of sampling methods and reporting metrics across studies complicates comparative analysis, underscoring the need for standardized analytical frameworks in the region.
Risk Assessment of Microplastic Exposure in the Marine Sediment of Southern Central Waters of Vietnam
Researchers collected sediment samples from 14 sites in southern central Vietnamese coastal waters and detected microplastics at all locations (100–1,350 MPs/kg), identifying fibers and fragments as the dominant forms and nine polymer types, providing the first microplastic baseline for this region.
Microplastics in freshwater and marine ecosystems: Occurrence, characterization, sources, distribution dynamics, fate, transport processes, potential mitigation strategies, and policy interventions
This review summarizes research on microplastic pollution across freshwater and marine ecosystems on all six continents, finding that polyethylene and polypropylene are the most common types found in water. The study highlights that microplastics serve as carriers for toxic chemicals and can move up the food chain, ultimately posing risks to human health through seafood consumption and drinking water.
A systematic review on microplastic pollution in water, sediments, and organisms from 50 coastal lagoons across the globe
This systematic review examined microplastic pollution in 50 coastal lagoons worldwide. These important ecosystems showed higher microplastic levels near populated areas with heavy human activity. Fibers and fragments made of polyethylene, polyester, and polypropylene were the most common types found, highlighting how everyday plastics end up contaminating the waters where our seafood comes from.
An integrated assessment of microplastic pollution in coastal surface water and sediment of Japan
Researchers conducted a comprehensive survey of microplastic pollution across 14 coastal locations around Japan from Hokkaido to Okinawa, measuring concentrations of 288.7 g/km2 in surface water and 1,185 kg/km2 in sediment and characterizing polymer types, shapes, and size distributions.
The fate of microplastic in marine sedimentary environments: A review and synthesis
A systematic review of 80 papers on microplastics in marine sediments found median concentrations varied widely by sediment environment, with fibers dominating many locations, and showed that sediment grain size and organic carbon content influence microplastic accumulation.
A systematic review of microplastic pollution in rivers across Asia
This systematic review found that microplastic pollution is widespread across Asian rivers, with fibers and fragments from synthetic textiles and packaging being the most common types. Since these rivers provide drinking water and sustain fisheries for billions of people, the contamination represents a significant pathway for human microplastic exposure across the most populated continent.
A Study on the Distribution of Microplastics in the South Coast of Korea and Gwangyang Bay
This study characterized the distribution and abundance of microplastics in surface water along the south coast of South Korea, finding widespread contamination with fibers and fragments across multiple sampling sites. Polymer analysis identified polyethylene, polypropylene, and polystyrene as the dominant types.
Occurrence of microplastics in commercial marine dried fish in Asian countries
Researchers examined 14 types of commercially available dried fish products from seven Asian countries and found microplastics present in all samples tested. The most common types were fibers and fragments, with polymers like polyethylene and polypropylene being frequently identified. The findings raise concerns about widespread human dietary exposure to microplastics through popular dried seafood products consumed across Asia.

Microplastic concentrations in sediments were highest near urban and industrial coastlines, with fibers and fragments as the most common types.
Mikromuovit Aasian rannikkovesissä
This literature review examined the sources and quantities of microplastics in the coastal waters of Asian countries, finding that the region contributes disproportionately to global microplastic pollution due to its large population, high plastic consumption, and inadequate waste management infrastructure.
A Decade of Microplastic Ingestion in Coral Fish: A Systematic Review of Trends in Asia
This systematic review summarizes a decade of research on microplastic ingestion by coral reef fish in Asia. It found widespread contamination across species, which matters for human health because many of these fish are commonly consumed as seafood in the region.
