ClearTrophic-level accumulation and transfer of legacy and emerging contaminants in marine biota: meta-analysis of mercury, PCBs, microplastics, PFAS, PAHs
This meta-analysis found that microplastics and PAHs show strong bioaccumulation with increasing trophic level and lifespan in marine species, alongside legacy pollutants like mercury and PCBs. Microplastics displayed clear biomagnification patterns across all trophic levels, highlighting their persistence and potential to disrupt marine food webs over multiple generations.
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.
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.
Investigating microplastic trophic transfer in marine top predators
Researchers investigated whether microplastics can transfer through the food chain by analyzing the scat of captive grey seals and the wild mackerel they were fed. They found microplastics in about half of the seal scat samples and a third of the fish, with similar particle types in both. The study suggests that trophic transfer is a plausible route for microplastics to move up marine food chains to top predators.
Investigating microplastic trophic transfer in marine top predators
Researchers investigated trophic transfer of microplastics in grey seals by analyzing digestive tracts of wild-caught Atlantic mackerel (fed to captive seals) alongside seal scat. Microplastics were detected in both prey fish and seal scat, providing empirical in natura evidence for trophic transfer in a marine top predator.
Polymer composition of microplastics in marine organisms across trophic levels
Researchers reviewed data from 16 studies to examine which types of microplastics are found in marine organisms across different levels of the food chain. They found that polyethylene, polypropylene, and polyethylene terephthalate were the most common polymers, with accumulation patterns varying between herbivores, omnivores, and carnivores. The study highlights how microplastic contamination is widespread throughout marine food webs, raising concerns about potential transfer to humans through seafood consumption.
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.
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.
Observing the Effects of Marine Debris Bioaccumulation and Biomagnification
This study examines how marine debris, particularly microplastics and heavy metals, bioaccumulates and biomagnifies through marine food webs, with organisms ingesting microplastics as they move through ocean currents. The review considers the ecological consequences of microplastic ingestion across trophic levels and the implications for food chain safety as humans sit at the top of the marine food web.
Ecological impact of microplastic pollution on marine food webs
This review examines how microplastic pollution disrupts marine food webs, tracing the transfer of plastic particles and associated chemicals from plankton through fish to top predators and analyzing the ecological consequences for marine biodiversity and ecosystem functioning.
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.
Kelp forest food webs as hot spots for the accumulation of microplastic and polybrominated diphenyl ether pollutants
Researchers measured microplastic and polybrominated diphenyl ether concentrations across trophic levels in kelp forest food webs, identifying these ecosystems as hotspots for the accumulation of both contaminant classes.
What goes in, must come out: Combining scat‐based molecular diet analysis and quantification of ingested microplastics in a marine top predator
By combining molecular diet analysis from seal scat with quantification of ingested microplastics, researchers found that a marine top predator was regularly ingesting plastic particles, with exposure likely mediated through prey species that had themselves ingested plastics. The study demonstrates trophic transfer of microplastics through a food chain to a marine mammal predator.
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.
Trophic transfer of DDE, BP-3 and chlorpyrifos from microplastics to tissues in Dicentrarchus labrax
Researchers demonstrated trophic transfer of DDE, BP-3, and chlorpyrifos from contaminated microplastics to European sea bass tissues, providing evidence that microplastics serve as vectors for chemical contaminant bioaccumulation through the food chain.
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.
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.
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.
Trophic Transfer of Differentially Hydrophobic Nanoplastics along Marine Food Chains and Related Toxicity
Researchers studied how surface hydrophobicity affects the movement of nanoplastics through a marine food chain from algae to mysids to fish. They found that more hydrophobic nanoplastics accumulated at significantly higher levels in organisms at each stage of the food chain, suggesting that surface properties play an important role in determining how nanoplastics bioaccumulate in marine ecosystems.
