ClearMicroplastic accumulation in marine organisms across trophic levels along the west coast of India
This study compared microplastic accumulation across trophic levels — including invertebrates, small fish, and large fish — at two locations along the west coast of a marine region. MP abundance decreased with increasing trophic level, suggesting dilution rather than biomagnification, but species at higher trophic positions still carried measurable contamination.
Microplastics in the Indian Ocean: a review of the ingestion and trophic transfer in commercial pelagic fish
This review examined microplastic ingestion and trophic transfer in the Indian Ocean, synthesizing evidence that MPs accumulate across marine food webs from zooplankton to large fish and marine mammals, and estimating the dietary MP exposure of human consumers of Indian Ocean seafood.
Assessment of microplastic bioconcentration, bioaccumulation and biomagnification in a simple coral reef food web
Researchers assessed microplastic bioconcentration, bioaccumulation, and biomagnification across three trophic levels in a coral reef food web, including zooplankton, benthic crustaceans, and reef fish. The study suggests that microplastics accumulate differently depending on species and trophic position, providing important baseline data for understanding ecological risks of microplastic contamination in coral reef ecosystems.
Application of marine organisms at multi-trophic level to study the integrated biological responses induced by microplastics through food-chain
Researchers used marine organisms across multiple trophic levels to study how microplastics move and accumulate through the food chain, finding that toxicological effects intensify at higher trophic levels due to bioaccumulation of plastic particles and associated chemical pollutants.
Exploring transfer of microplastics in the trophic chain: a prey-predator interaction case in the Strait of Messina
Researchers examined the transfer of microplastics across trophic levels in a prey-predator marine food web, tracking particles from prey organisms to predators. The study confirmed trophic transfer of microplastics and found that predators can accumulate higher particle concentrations than their prey.

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.
Microplastics Trophic Transfer in Seafood Varieties Caught from the Coastal Waters off Negombo
This study examined microplastic trophic transfer among five commercially important seafood species caught from coastal waters off Negombo, Sri Lanka, analyzing tissues to trace how plastics move through the food web. Results showed microplastics were present across trophic levels, with contamination patterns differing by species and tissue type.
The patterns of trophic transfer of microplastic ingestion by fish in the artificial reef area and adjacent waters of Haizhou Bay
Researchers examined microplastic ingestion by fish in Haizhou Bay's artificial reef area, finding evidence of trophic transfer where predatory species accumulated more microplastics than lower trophic level species in the food web.
Trophic transfer of polyester microfibres across a multi-level marine food web
Researchers tracked how polyester microfibers move through a coral reef food chain, from tiny copepods to shrimp to fish. They found that microplastic concentrations increased up to 14.6-fold between trophic levels, demonstrating that these particles accumulate as they pass up the food web. The study highlights how microplastics can concentrate in marine organisms through normal predator-prey relationships.
Ingestion of microplastics in commercially important species along Thoothukudi coast, south east India
Researchers found microplastics in the guts of 12 commercially important marine species along India's Thoothukudi coast, with herbivores showing the highest ingestion rates and evidence of biomagnification across trophic levels, suggesting feeding habits — not habitat or body size — drive microplastic accumulation.
Trophic transfer of microplastics in the aquatic ecosystem of Sundarbans mangrove forest, Bangladesh
Researchers sampled organisms across four trophic levels in the aquatic ecosystem of the Sundarbans mangrove forest in Bangladesh, finding microplastic abundance increased with trophic level from an average of 0.56 items per primary consumer to 4.17 items per quaternary consumer. The positive correlation between microplastic abundance and trophic level confirmed trophic transfer across the food web.
Bioaccumulation, biomagnification and ecological risk evaluation of microplastics in Sanggou Bay, China
Researchers studied microplastic contamination in marine organisms across Sanggou Bay, China, and found plastic particles in every species examined, with concentrations varying by organism. They discovered evidence of biomagnification, meaning microplastics accumulated to higher concentrations up the food chain, with smaller particles, fibers, and polystyrene showing the strongest transfer between species. The study provides new evidence that the physical characteristics of microplastics influence how they move through marine food webs.
Exploring transfer of microplastics in the trophic chain: a prey-predator interaction case in the Strait of Messina
This study examined how microplastics transfer through marine food webs via predator-prey interactions, tracking the movement of particles across trophic levels. Results confirmed that microplastics can be transferred from prey to predator and accumulate at higher trophic levels, posing risks to top predators and fisheries.
Ingestion and transfer of microplastics in the planktonic food web
Researchers demonstrated that microplastics are ingested and transferred through a planktonic food web, with particles passing from primary producers to zooplankton grazers and on to predatory plankton, establishing trophic transfer as a real pathway for microplastic movement through marine food chains.
Bioaccumulation and biomagnification of microplastics in marine organisms: A review and meta-analysis of current data
This meta-analysis reviews current evidence on whether microplastics accumulate and concentrate as they move up the marine food chain. The findings have direct implications for seafood safety, since biomagnification would mean that larger predatory fish consumed by humans could contain higher concentrations of microplastics and their associated chemical additives.
Effect of alternative natural diet on microplastic ingestion, functional responses and trophic transfer in a tri-trophic coastal pelagic food web
Researchers studied how microplastics move through a three-level marine food chain, from zooplankton prey to planktivorous fish, and how the availability of natural food affects microplastic ingestion. When natural food was scarce, organisms consumed more microplastics, and the particles transferred efficiently up the food chain. This study demonstrates that microplastics in the ocean can accumulate through the food web and reach fish species that humans commonly eat.
Microplastic characterization in the stomachs of swordfish (Xiphias gladius) from the western Mediterranean Sea
Researchers analyzed the stomachs of 49 swordfish from the western Mediterranean Sea and found microplastics in 80% of them, predominantly small fibers made of polyethylene terephthalate. Comparing samples from two time periods showed that the frequency of microplastic ingestion increased over time, rising from about 70% to 90% of fish examined. The study highlights growing microplastic exposure in large predatory fish that are widely consumed by humans.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics and the chemicals they carry transfer through marine food webs from lower to higher trophic levels, and what this means for human health given that people consume marine fish and seafood. It identifies microplastics as a vector for bioaccumulation of persistent organic pollutants in ways that ultimately reach humans.
Abundance and Distribution of Microplastics in Fish by Trophic Level in Kupang Bay, Indonesia
Researchers surveyed microplastic abundance in fish from Kupang Bay, Indonesia across herbivore and carnivore trophic levels and multiple organs (GIT, gills, muscle), finding carnivores accumulated more microplastics than herbivores and gills showed the highest concentrations.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics move through marine food webs via trophic transfer and carry chemical contaminants that can accumulate in higher predators, including humans. Researchers found that microplastics readily sorb pollutants from surrounding waters and release them after being ingested by organisms, potentially amplifying toxic effects at each level of the food chain. The study underscores the need for more research on bioaccumulation factors and the implications of seafood-mediated microplastic exposure for human health.
