Environmental health risk analysis of microplastics due to consumption of squid and mussels at coastal area
Researchers measured microplastic contamination in mussels and squid from a coastal area in Indonesia and assessed the potential health risks to local communities who consume these seafood products. They found 23 microplastic particles across the samples, primarily fibers made of polyethylene and polypropylene. Statistical modeling showed a significant link between microplastic concentrations in the seafood, intake rates, and health risk indicators for the consuming population.
Microplastic pollution in the Indian Ocean: Fiber-dominated contamination and comparative bioaccumulation in Auxis thazard and Symplectoteuthis oualaniensis
Researchers surveyed microplastic pollution across 32 sites in the Indian Ocean and in the tissues of two marine species, frigate tuna and flying squid. Microplastics were detected at nearly 94% of sampling sites, predominantly fiber-shaped particles from synthetic textiles, with the Arabian Sea showing the highest concentrations. The study found evidence of microplastic bioaccumulation in both species, raising concerns about contamination moving through the marine food chain.
Abundance and Characteristics of Microplastics Found in The Gastrointestinal Tract of Commercial Marine Fish from Bitung, North Sulawesi – Indonesia
Researchers analyzed microplastic abundance and characteristics in the gastrointestinal tracts of commercial marine fish from Bitung, North Sulawesi, Indonesia, providing baseline contamination data for commercially important species from a major Indonesian fisheries region.
Microplastic pollution in seawater and marine organisms across the Tropical Eastern Pacific and Galápagos
Researchers sampled water and seafood across 453,000 square kilometers of the Tropical Eastern Pacific and Galápagos Islands, finding microplastics in 100% of water samples and in every species of fish, squid, and shrimp collected. This confirms that microplastic contamination is pervasive even in remote ocean regions, raising concerns for both marine ecosystems and human food safety.
Plastic for dinner? Observations of frequent debris ingestion by pelagic predatory fishes from the central North Pacific
Researchers documented frequent ingestion of plastic debris by large predatory pelagic fishes — including mahi-mahi, opah, and swordfish — sampled from the central North Pacific between 2007 and 2012. The findings demonstrate that plastic contamination extends beyond small planktivorous fish and seabirds to apex pelagic predators, with implications for trophic transfer of associated chemical contaminants.
Microplastic ingestion and plastic additive detection in pelagic squid and fish: Implications for bioindicators and plastic tracers in open oceanic food webs
Researchers examined microplastic ingestion in fish and squid from the open Northeast Atlantic and detected phthalate plasticizers in their tissues. Both fish species and all three squid species had ingested microplastics, with fibers being the most common type. The presence of plastic additives in these open-ocean species suggests that microplastic contamination and associated chemical exposure extend well beyond coastal areas into the deep ocean food web.
Microplastic contamination and risk assessment in blue shark (Prionace glauca) from the eastern tropical Pacific Ocean
Researchers quantified microplastic abundance and characteristics in the digestive tracts of blue sharks (Prionace glauca) from the eastern tropical Pacific Ocean and conducted a risk assessment for microplastic pollution in this pelagic apex predator. The study found microplastics in 39.1% of specimens — predominantly blue fibers sized 46 to 3,220 micrometers — with similar abundance across sexes, indicating widespread exposure of blue sharks to microplastic pollution in open ocean environments.
From surface water to marine fauna: Assessing microplastic pollution in the northeastern Indian Ocean ecosystem
Researchers characterized microplastic contamination in surface waters and two mid-trophic marine species—frigate tuna and purpleback flying squid—in the northeastern Indian Ocean, finding MPs in 96.7% of water samples and 66.7% of organisms, with rayon fibers from textile laundering dominant and substantial accumulation in edible muscle tissue.
From prey to predators: Evidence of microplastic trophic transfer in tuna and large pelagic species in the southwestern Tropical Atlantic
Researchers found evidence of microplastic trophic transfer from prey to tuna and large pelagic predators in the southwestern Tropical Atlantic, demonstrating that plastic contamination moves through marine food chains to economically important fish species.
Ingestion of plastic by fish destined for human consumption in remote South Pacific Islands
Plastic was found in the digestive tracts of 24 fish species collected from local fishermen and markets across remote South Pacific islands, with species consuming plastic regardless of feeding guild. The results raise public health concerns for Pacific island communities where fish is a dietary staple and plastic marine debris is widespread.
