ClearMicroplastic 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.
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.
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.
Distribution 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.
Microplastic pollution in sediments from the Bohai Sea and the Yellow Sea, China
Researchers sampled sediments from the Bohai Sea and Yellow Sea and found widespread microplastic contamination, with fibers and fragments as the dominant forms, and higher concentrations near river mouths and urban coastlines.
Microplastic pollution in the environment and organisms of Xiangshan Bay, East China Sea: An area of intensive mariculture
Researchers assessed microplastic pollution across water, sediment, and marine organisms in Xiangshan Bay, a major mariculture area in China, finding that intensive aquaculture in the enclosed inner bay concentrated microplastics and that fish ingested more particles than other organisms.
Food-web transfer of microplastics between wild caught fish and crustaceans in East China Sea
Researchers examined microplastic contamination in 11 fish species and 8 crustacean species from the Zhoushan fishing ground in the East China Sea. They found microplastics, predominantly polyester fibers, in both gill and gastrointestinal tissues across nearly all species studied. The results suggest that microplastics may accumulate at higher trophic levels, raising concerns about food-web transfer of plastic pollution in this heavily fished region.
Microplastics in Different Tissues of Five Common Fishes from Yuehai Lake: Accumulation, Characterization, and Contamination Assessment
Researchers examined microplastic contamination in the gills and digestive tracts of five fish species from a Chinese lake, finding that fish eating a wider variety of foods accumulated more particles. Different plastic polymer types dominated in different tissues, confirming that microplastics move through freshwater food webs and reach fish that humans consume.
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.
Microplastic accumulation in fish from Zhanjiang mangrove wetland, South China
Microplastics were found in multiple fish species collected from Zhanjiang mangrove wetlands in South China, with contamination levels and particle types varying by species and feeding behavior. The study highlights how microplastics accumulate in fish living in mangrove ecosystems and enter coastal food chains.
Occurrence and distribution of microplastics in commercial fishes from estuarine areas of Guangdong, South China
Researchers analyzed the abundance, characteristics, and spatial distribution of microplastics in six commercial fish species from estuarine areas of Guangdong, South China, providing quantitative data on microplastic ingestion in fish from one of China's most plastic-polluted coastal regions.
Progress on microplastics research in the Yellow Sea, China
This review synthesizes progress on microplastics research in China's Yellow Sea, documenting plastic debris across surface water, water column, sediments, and marine organisms, and highlighting the influence of dense coastal human activity on this major Western Pacific marginal sea.
A review of microplastic pollution in seawater, sediments and organisms of the Chinese coastal and marginal seas
This review compiled microplastic abundance and characteristics data from seawater, sediments, and marine organisms across China's coastal and marginal seas, finding widespread contamination linked to China's extensive plastic production and mismanaged waste streams.
Microplastic and associated emerging contaminants in marine fish from the South China Sea: Exposure and human risks
Researchers found microplastics in all 14 marine fish species tested from the South China Sea, along with antibiotics and PFAS chemicals. Fish with more microplastics in their guts also had higher levels of certain chemical contaminants in their flesh, suggesting microplastics may act as carriers that increase the amount of harmful chemicals in seafood consumed by humans.
Microplastic contamination in seafood from Dongshan Bay in southeastern China and its health risk implication for human consumption
Researchers investigated microplastic contamination in eight popular seafood species from Dongshan Bay in southeastern China and assessed potential human health risks. The study characterized the abundance, size, shape, and polymer type of microplastics found in the seafood samples. The findings suggest that consuming contaminated seafood represents a meaningful exposure pathway for microplastic ingestion, though the specific health implications require further study.
Microplastic pollution in the Maowei Sea, a typical mariculture bay of China
Researchers surveyed microplastic pollution in the Maowei Sea, a major mariculture bay in China, analyzing both water samples and fish from 12 species. They found microplastics in all fish gastrointestinal tracts and in the gills of many individuals, with demersal species showing significantly higher contamination than pelagic ones. The highest water concentrations were found near oyster nurseries and harbour areas, suggesting that farmed seafood from this region is regularly exposed to microplastic contamination.
Microplastics and mesoplastics in fish from coastal and fresh waters of China
Researchers surveyed fish from both coastal marine and freshwater environments across China and found microplastics in species from both habitats, with differences in contamination levels and plastic types reflecting each environment's pollution profile.
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.
Investigation of Microplastics in Surface Water and Estuarine Mullet Mugil cephalus from 23 Estuary Areas, South China
Researchers surveyed microplastic contamination in surface water and estuarine mullet from 23 estuary areas in South China, using the widely distributed fish species as a biomonitor to assess the extent of microplastic ingestion in coastal environments.
Occurrence and distribution of microplastics in the adjacent environment of Yellow River Delta, China
Researchers assessed microplastic pollution across water, sediment, and soil samples in the Yellow River Delta of China. The study found microplastic concentrations ranging from 0.5 to nearly 8 particles per liter in water and up to 4,200 particles per kilogram in sediments, with polyethylene and polypropylene being the most common polymer types, indicating widespread plastic contamination in this coastal environment.
