Microplastic contamination in seafood from Dongshan Bay in southeastern China and its health risk implication for human consumption
AI summary Read the abstract
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 (MP) pollution has been a considerable concern due to its ubiquity in the environment and its potential to harm human health. Unfortunately, the exact levels of MP in various species of seafood species have not been established. It is also unclear whether or not consuming seafood contaminated with MPs directly jeopardizes human health. Here, eight popular species of seafood in Dongshan Bay, China were investigated to determine the presence of MP pollution and its implications on human health. The abundance, color, size, shape, type, surface morphology, danger of the MPs extracted from the seafood were analyzed. Results showed that the average MP abundance in the shellfish and fish was 1.88 ± 1.44 and 1.98 ± 1.98 items individual, respectively. The heavy presence of fibers may be attributed to the shellfish and fish's feeding behaviors as well as their habitat and environment. The sizes of MPs found were below 1.0 mm. The main types of MP found in the shellfish were PES and PET, whereas the main types found in the fish were PS and PES. Risk assessment suggested that MPs in the shellfish (risk Level V) posed a greater and more direct threat to human health if the shellfish is eaten whole. The MPs in the gastrointestinal tracts (GITs) of fish (risk Level IV) have a relatively limited effect on human health since GITs are seldom consumed by humans unless the fish is heavily processed (canned or dried). MPs-induced health risk is predicted using a technique called molecular docking. The results of this study not only establish levels of MP pollution in popular seafood species but also help understand the implications of consuming MP-contaminated seafood on human health.

An examination of the occurrence and potential risks of microplastics across various shellfish
AI summary Read the abstract
Researchers compared microplastic contamination levels in commercial shellfish from northern (Qingdao) and southern (Xiamen) China, finding microplastics in 70-100% of samples. The study assessed potential human health risks from consuming contaminated shellfish, with microplastic abundances varying across species and geographic locations.
Microplastics contamination in bivalves from the Daya Bay: Species variability and spatio-temporal distribution and human health risks
AI summary Read the abstract
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.
Microplastic pollution and ecological risk assessment in an estuarine environment: The Dongshan Bay of China
AI summary Read the abstract
Researchers conducted the first survey of microplastic pollution in Dongshan Bay, a Chinese estuary, and found concentrations averaging 1.66 particles per cubic meter of surface water. The most common plastics were polypropylene, polyethylene, and polystyrene foam, likely originating from local fishing and aquaculture activities. An ecological risk assessment rated the bay at a moderate hazard level, establishing important baseline data for future monitoring.

Accumulation of microplastics in typical commercial aquatic species: A case study at a productive aquaculture site in China
AI summary Read the abstract
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.
