ClearMicroplastics 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.
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.
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.
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.
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.
Large size (>100‐μm) microplastics are not biomagnifying in coastal marine food webs of British Columbia, Canada
Researchers quantified microplastic uptake across multiple trophic levels in a coastal British Columbia food web including bivalves, crabs, echinoderms, and fish, finding no evidence of biomagnification for particles larger than 100 micrometers. Suspension feeders and small planktivorous fish had the highest ingestion rates, and rapid excretion appeared to prevent accumulation in higher predators.
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.
A critical review on various trophic transfer routes of microplastics in the context of the Indian coastal ecosystem
This review examines how microplastics accumulate along the Indian coastline through ingestion and bioaccumulation across species including plankton, fish, turtles, and seabirds. The findings highlight India's coastal biodiversity as being at significant risk, with implications for the millions of people who rely on marine fisheries for food.
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.
Microplastics accumulation in pelagic and benthic species along the Thoothukudi coast, South Tamil Nadu, India
Researchers surveyed microplastic contamination in the digestive tracts of fish and shellfish along the Thoothukudi coast in southern India. They found microplastics in both open-water and bottom-dwelling species, with bottom-dwellers accumulating slightly more particles, predominantly polyethylene fibers. The findings confirm that microplastic contamination is widespread across marine habitats in the region and underline the need for better plastic waste management.
Microplastic accumulation and biomagnification in a coastal marine reserve situated in a sparsely populated area
Microplastics were quantified across a benthic food web at a remote California marine reserve, finding concentrations of 36.59 plastics/L in seawater, and with densities increasing from macroalgae to herbivorous snails to predatory invertebrates, suggesting biomagnification potential in coastal food webs. The study provides rare evidence of microplastic concentration increases across trophic levels in a near-pristine coastal ecosystem.
Distribution of microplastics in seafloor sediments and their differential assimilation in nearshore benthic molluscs along the south-west coast of India
Researchers investigated microplastic contamination in seafloor sediments and benthic molluscs along a 300-kilometer stretch of India's southwest coast. They found significant MP levels in both sediments and all four mollusc species studied, with scavenging gastropods accumulating the highest concentrations. The study reveals that feeding strategy is a key factor in microplastic uptake by marine organisms, with ecological risk indices indicating elevated contamination levels in most sampling stations.
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.
First evidence of microplastics bioaccumulation by marine organisms in the Port Blair Bay, Andaman Islands
Microplastics were detected in water, sediment, zooplankton, finfish, and shellfish in Port Blair Bay in the Andaman Islands, India, with zooplankton showing the highest retention of particles relative to body size. Nylon, acrylic, and ionomer were the most common polymer types, providing baseline contamination data for this coastal ecosystem.
Microplastic contamination in thirty commercially important fish species: Distribution, polymer composition, pollution indices, and human health risks
Researchers examined microplastic contamination in 600 specimens across 30 commercially important fish species from the Indian coast, finding the highest accumulation in the gastrointestinal tract with carnivorous species carrying the greatest burden. Polyethylene and polypropylene fibers were the dominant particle types, and human health risk assessment showed measurable daily intake from consuming these fish, with pollution indices indicating considerable to medium hazard risk levels.
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.
The threat of microplastics: Exploring pollution in coastal ecosystems and migratory shorebirds along the west coast of India
Researchers surveyed microplastic contamination across ten coastal sites on India's west coast, testing water, sediment, invertebrate prey, and shorebird droppings. Microplastics, mostly fibers, were found in all sample types, with water identified as the primary pathway for spreading plastics through the food chain. The study demonstrates how microplastics move from water through prey animals to top predators, illustrating the food chain transfer that ultimately could affect human seafood consumption.
Occurrence of microplastics in epipelagic and mesopelagic fishes from Tuticorin, Southeast coast of India
Researchers investigated microplastic contamination in seawater and six fish species from different ocean depth habitats near Tuticorin, India. The study found microplastics in the gastrointestinal tracts of both epipelagic and mesopelagic fish, with contamination levels varying by species and habitat, suggesting that microplastic exposure extends across different marine depth zones and could affect human exposure through seafood consumption.
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.
