ClearMicroplastic Bioaccumulation in Selected Finfish Species Harvested from Northwest Coastal Waters, Sri Lanka: A Potential Risk to Human Health?
Researchers analyzed microplastic bioaccumulation in edible and non-edible tissues of four finfish species from northwest coastal Sri Lanka, finding that 96% of samples were contaminated with particles in the 0.06-0.11 mm range. Tuna (Katsuwonus pelamis) showed the highest MP levels in edible muscle tissue at 1.1 MP/g, raising concerns about human dietary exposure.
Microplastic Contamination in Shrimps from the Negombo Lagoon—Sri Lanka
Researchers analyzed microplastic contamination in two species of shrimp from Sri Lanka's Negombo Lagoon, examining both gastrointestinal tracts and gills. The study found microplastics present in all sampled shrimp, raising concerns about human dietary exposure to microplastics through seafood consumption in coastal communities.
Bioaccumulation and trophic transfer of microplastics in oceanic food webs
Researchers quantified microplastic bioaccumulation and trophic transfer across food web levels in the Laccadive Sea, Western Indian Ocean, from zooplankton through top predators. Microplastics were found in 95% of samples, with highest concentrations in predatory fish like swordfish (832 items/individual), demonstrating substantial biomagnification across trophic levels.
Distribution of Microplastics in Coastal Waters and Their Implications for the Marine Food Chain
This study investigated microplastic distribution in three coastal zones in Indonesia—urban, industrial, and conservation—and examined implications for marine food chain transfer. Industrial areas showed highest contamination, and shellfish contained higher microplastic burdens than finfish, suggesting trophic transfer risk differs by feeding strategy.
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.
Microplastic 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.
Assessing the bioaccumulation of microplastics in commercially important fish species
Researchers assessed microplastic accumulation in commercially important fish species from coastal and offshore waters, finding significant differences between species based on feeding strategies and habitat depth. Filter feeders and omnivorous species accumulated more microplastics than others, reflecting diet-based differences across trophic levels. The study raises concerns about human dietary exposure to microplastics through widely consumed seafood products.
Distribution of Microplastics in Coastal Waters and Their Implications for the Marine Food Chain
Researchers sampled surface water, sediments, and marine organisms from urban, industrial, and conservation coastal zones in Indonesia to assess microplastic distribution and food chain implications. Industrial zones had the highest microplastic concentrations, and filter feeders accumulated more particles than fin fish, indicating distinct exposure pathways through the marine food web.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics act as vectors for chemical contaminants through marine food webs, discussing the factors influencing ingestion, the biological impacts of sorbed chemicals, and evidence for trophic transfer across multiple trophic levels. Researchers highlight that existing lab studies use unrealistically high concentrations and that no study has yet tracked microplastic-contaminant transfer from seafood to humans.
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.
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.
Impact of Microplastic Ingestion on Commercial Fish: A Trophic-Level Analysis
Researchers analyzed over 1,600 fish from two Colombian estuaries and found a significant link between a fish species' position in the food chain and the amount of microplastics it ingests. Fish that feed at higher levels of the food web accumulated more microplastics, and those that had ingested plastics showed signs of poorer body condition. The findings highlight how microplastics build up through the marine food chain, with potential consequences for both ecosystem and human health.
Microplastics and seafood: lower trophic organisms at highest risk of contamination
This systematic review summarizes existing research on microplastic contamination in commercially important seafood species. The findings show that organisms lower on the food chain, like shellfish and small fish, tend to accumulate the most microplastics. Since many people eat these organisms whole, including their digestive tracts, this represents a direct pathway for microplastics to enter the human diet.
Microplastic in tissue of marine organisms
This review summarizes microplastic detection across various marine organism tissues, cataloging accumulation in fish, invertebrates, and marine mammals and highlighting that ingestion and trophic transfer are widespread across marine food webs.
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.
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.
