ClearDistribution and Characteristics of Microplastics in Barnacles and Wild Bivalves on the Coast of the Yellow Sea, China
Researchers surveyed microplastic contamination in wild barnacles and bivalves along the Yellow Sea coast of China. They found microplastics in all sampled organisms, with fibers being the dominant type, and observed spatial variation in contamination levels across different coastal sites. The study provides baseline data on microplastic pollution in wild shellfish populations that are smaller and potentially more vulnerable than farmed species.
Distribution of microplastics in different tissues of major commercial catches in different functional areas of the South Yellow Sea
Researchers investigated microplastic distribution across different tissues of six commercial fish and crustacean species from the South Yellow Sea, finding MPs ubiquitous across species with an average abundance of 5.19 items per individual.
Microplastics in commercial clams from the intertidal zone of the South Yellow Sea, China
Researchers examined microplastic contamination in commercial clams from the intertidal zone of China's South Yellow Sea, identifying polymer types and raising concerns about food safety and ecological risks in a commercially important shellfish habitat.
Microplastic accumulation in bivalves collected from different coastal areas of Vietnam and an assessment of potential risks
Researchers analyzed microplastic accumulation in five common bivalve species collected from aquaculture areas along the coast of Vietnam, finding microplastics in all samples with an average of about 10.84 items per individual. Fibers were the most common shape, concentrated in gills and digestive glands, and a risk assessment suggested potential implications for human health through seafood consumption.
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.
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.
Microplastics in commercial bivalves from China
Researchers analyzed microplastics in commercially sold bivalves from China, finding contamination across multiple species and geographic origins, with implications for human dietary microplastic exposure through shellfish consumption.
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.
Characteristics and retention of microplastics in the digestive tracts of fish from the Yellow Sea
Researchers systematically characterized microplastics in 19 fish species from the Yellow Sea coast of China, finding plastic retention in 34% of individual fish sampled, with fibers dominating and significant variation in microplastic load by species and habitat.
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.
Microplastic contamination in filter-feeding bivalves inhabiting the natural ecosystem of Da Nang Bay: An investigation of oysters (Ostrea rivularis) and green mussels (Perna viridis)
Researchers found microplastics in 100% of examined oysters and green mussels from Da Nang Bay, Vietnam, with average densities of 3.5 items per gram of tissue, exceeding average contamination levels seen in seafood across Asia. Mussels showed considerably higher MP accumulation than oysters, with black plastic particles under 0.5 mm in fibrous form being the dominant type found.
Microplastics contamination in bivalves from the Daya Bay: Species variability and spatio-temporal distribution and human health risks
Researchers assessed microplastic contamination in six species of bivalves from Daya Bay, China, finding microplastics present in 87 to 93% of individuals sampled. Sediment-dwelling bivalves had higher microplastic levels than water-dwelling species, and the types of microplastics found in the shellfish matched those in the surrounding seawater and sediment. A risk assessment based on polymer hazard levels indicated that microplastic contamination in these bivalves may pose health risks to humans who consume them as seafood.
The prevalence and potential implications of microplastic contamination in marine fishes from Xiamen Bay, China
Researchers found microplastic contamination in nine fish species from Xiamen Bay, China, with abundances of 1-8 items per individual, dominated by fibers (59%) and polymers like polyamide and rayon, highlighting seafood contamination risks.
The abundance and characteristics of microplastics in commonly consumed shellfish in the Jiangsu coastal region of China
Researchers measured microplastic abundance and characteristics in three commercially consumed shellfish species from Jiangsu, China, finding MPs in all species with clams containing the highest concentrations and fibers from fishing gear and textiles as the dominant type, estimating annual human intake from shellfish consumption.
The occurrence and exposure of microplastics in bivalves from Qingdao, China
Researchers surveyed microplastic contamination in bivalves such as clams and mussels from the coast of Qingdao, China, and assessed human dietary exposure from eating them. They found an average of about one microplastic particle per individual shellfish, with fibers and rayon being the most common types. The study suggests that regular bivalve consumption in the region contributes to ongoing human microplastic exposure.
Characteristics and potential human health risks of microplastics identified in typical clams from South Yellow Sea Mudflat
Researchers analyzed microplastic contamination in wild and farmed clams from the South Yellow Sea Mudflat in China and assessed potential human health risks from consuming them. They found microplastics in all clam samples, with wild clams containing higher levels than farmed clams, and fragment and fiber shapes being most common. The study estimates that adults consuming these clams could ingest hundreds of microplastic particles per kilogram of body weight annually, raising concerns about dietary exposure.
Accumulation of microplastics in typical commercial aquatic species: A case study at a productive aquaculture site in China
Researchers assessed microplastic accumulation in commercial fish, bivalves, and shrimp at an intensive aquaculture site in Xiangshan Bay, China. They found microplastics in all species sampled, mostly cellulose and polypropylene fibers, with aquaculture activities contributing to sediment contamination. However, the overall accumulation levels in the seafood were relatively low, suggesting that microplastics may not substantially increase health risks from consuming these species at this site.
Pollution Characteristics of Microplastics in Mollusks from the Coastal Area of Yantai, China
