Ingestion and accumulation of microplastics in small marine fish and potential human exposure: case study of Binh Dinh, Vietnam
Researchers investigated microplastic accumulation in five small marine fish species commonly consumed by coastal communities in Binh Dinh, Vietnam. They found microplastics present in fish from all sampling sites, with seasonal and species-level variation in contamination levels. The study estimates potential human dietary exposure to microplastics through fish consumption and raises food safety concerns for coastal populations relying on local seafood.
Microplastic presence in dried and fresh fish from seafood markets in Sri Lanka
Scientists examined both fresh and dried fish from seafood markets across Sri Lanka and found microplastics in over 82% of the samples, with fiber-shaped pieces making up more than 95% of the contamination. Fresh fish had higher contamination levels than dried fish, suggesting that preparation methods affect microplastic content. Since these small fish species are commonly eaten whole, consumers may be ingesting significant amounts of microplastics through popular seafood products.
Microplastic contamination in salt-cured fish and commercial sea salts: an emerging food safety threat in relation to UN Sustainable Development Goals (SDGs)
Researchers analyzed 22 species of salt-cured fish and commercial sea salts from the Indian east coast and found microplastic contamination substantially higher than global averages. Most of the microplastics were tiny fragments and fibers smaller than 250 micrometers, primarily made of PVC and polystyrene. The findings raise concerns about human exposure to microplastics through preserved seafood products and highlight the need for food safety monitoring.
Comparison of Presence of Microplastics in Two Edible Fish Species from South India
Researchers compared microplastic contamination in two edible fish species from South India, finding differences in the abundance and types of microplastics between species that likely reflect differences in feeding habits and habitat use.
Microplastics occurrence in water, sediment and edible small indigenous fish species in seasonal freshwater wetland ecosystems of Bangladesh
Researchers found microplastics in the guts, gills, and muscle tissue of three commonly eaten fish species from seasonal wetlands in Bangladesh. Dried fish contained more microplastics than fresh fish, suggesting that the drying process concentrates plastic particles. Since these small fish are a dietary staple for local communities and are often eaten whole, this represents a direct pathway for microplastic exposure in human diets.
