Occurrence, abundance and characteristics of microplastics in some commercial fish of northern coasts of the Persian Gulf
Microplastics were found in muscle, liver, gill, and gastrointestinal tissues of 14 commercially fished species from the northern Persian Gulf, with gastrointestinal tissues showing the highest contamination and muscle tissue showing very low levels, suggesting limited translocation from gut to edible flesh in most species.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
Microplastic pollution in North Yellow Sea, China: Observations on occurrence, distribution and identification
Researchers surveyed microplastic pollution across the North Yellow Sea, documenting their occurrence, distribution, and characteristics, and finding widespread contamination with higher concentrations in coastal areas and near river inputs.
An evaluation of microplastic contamination in the marine waters and species in the coastal region of the South Yellow Sea, China
Researchers surveyed microplastic contamination across water, sediment, fish, and shellfish in the South Yellow Sea, China, finding plastics at every level of the food chain. Contamination was highest near river mouths that drain industrialized areas and decreased further offshore. Fish and bivalves showed significant microplastic uptake in their guts and gills, confirming that microplastics move from polluted rivers into coastal seafood that humans consume.
Abundance and characteristics of microplastics in commercial marine fish from Malaysia
Microplastics were found in the digestive tracts of eight commercially important marine fish species caught in Malaysian waters, with prevalence and particle types varying by species and location. The study raises food safety concerns for Malaysian seafood consumers and highlights the widespread occurrence of microplastic ingestion in wild-caught fish from Southeast Asian seas.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Abundance, characteristics and ecological risks of microplastics from South Yellow Sea Mudflat
Researchers surveyed microplastic contamination in the mudflats of the South Yellow Sea and found plastic particles in both the water and sediment at all sampling locations. Areas near estuaries and ports had higher levels of microplastics in the water, while purely coastal mudflats accumulated more in their sediments. Although overall pollution levels were rated as low, the types of plastic polymers present indicated the potential for significant ecological risk.
Microplastics in different tissues of fish and prawn from the Musa Estuary, Persian Gulf
Researchers analyzed multiple tissues of commercially important fish and prawns from the Persian Gulf and found microplastics present in guts, skin, muscle, gills, and liver across all species examined. The type and abundance of microplastics varied by species and sampling location, with bottom-dwelling fish accumulating the most particles. The findings are notable because they show microplastics penetrate beyond the digestive tract into edible muscle tissue, which is directly relevant to human consumption.
Enrichment Characteristics of Microplastics and Heavy Metals Accumulated in Bivalves in South Yellow Sea
Researchers analyzed three species of bivalves from the South Yellow Sea and found microplastics in all of them, averaging about nine particles per individual. The most common types were transparent fibers made of polyamide, and while heavy metals like zinc were also present, there was no clear statistical link between microplastic and heavy metal concentrations in the animals.
Microplastic ingestion by commercial marine fish from the seawater of Northwest Peninsular Malaysia
Researchers examined microplastic ingestion by four species of commercially important marine fish caught off the northwest coast of Peninsular Malaysia. The study found microplastics in the gastrointestinal tracts of the fish, with fibers being the most common type, highlighting the prevalence of microplastic contamination in seafood from this region.
High levels of microplastic pollution in the sediments and benthic organisms of the South Yellow Sea, China
High concentrations of microplastics were found in both sediments and benthic organisms from the South Yellow Sea, with fibers as the dominant type and polymer compositions reflecting regional land-based and marine sources. The study identifies benthic ecosystems of the South Yellow Sea as significantly impacted by microplastic pollution, with potential risks to bottom-dwelling communities.
The accumulation of microplastics in fish from an important fish farm and mariculture area, Haizhou Bay, China
Researchers investigated microplastic accumulation in six wild fish species from Haizhou Bay, a major fish farm and mariculture area in China, examining both digestive and non-digestive tissues. They found microplastics present in all fish species, with variation in abundance depending on species and tissue type. The findings raise concerns about microplastic transfer through aquaculture supply chains and potential implications for seafood safety.

Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
This study compared microplastic contamination across commercially relevant seafood species commonly consumed in the European market, characterizing both the morphological and chemical properties of particles found in edible tissue. Results showed widespread but variable contamination across species, with polymer types and particle abundance differing by species and tissue type.
Occurrence of microplastics in gastrointestinal tracts and gills of fish from Beibu Gulf, South China Sea
Researchers examined microplastic contamination in 24 fish species from Beibu Gulf in the South China Sea. Microplastics were detected in half the species, predominantly as transparent fibers found mainly in the stomach, with polyester and nylon being the most common polymers. The overall microplastic abundance was relatively low, and demersal fish tended to contain more particles than pelagic species.
Abundance and characteristics of microplastic in some commercial species from the Persian Gulf, Iran
Scientists examined microplastic contamination in the digestive tracts of five commercially important fish and shellfish species from the Persian Gulf, finding plastic particles in nearly 73 percent of all individuals sampled. Microfibers were the most common type, making up about 58 percent of particles found, and polymer analysis identified polypropylene and polyethylene as the dominant plastics. The study highlights that seafood from the Persian Gulf region is widely contaminated with microplastics, raising concerns about potential exposure for human consumers.
