ClearImportant ecological processes are affected by the accumulation and trophic transfer of nanoplastics in a freshwater periphyton-grazer food chain
Researchers found that nanoplastics bioaccumulate and transfer trophically in a freshwater periphyton-grazer food chain, affecting fundamental ecological processes and highlighting significant gaps in our understanding of nanoplastic risks in freshwater ecosystems.
Exploring Nanoplastics Bioaccumulation in Freshwater Organisms: A Study Using Gold-Doped Polymeric Nanoparticles
Researchers developed gold-doped polymer nanoparticles as traceable stand-ins for nanoplastics to study how these tiny particles accumulate in freshwater organisms including algae, zooplankton, and mussels. The approach enables more precise measurement of nanoplastic uptake across the food chain, helping scientists better understand the real-world bioaccumulation risks of plastic pollution in freshwater ecosystems.
Micro-Nano Plastics in Aquatic Environments: Associated Health Impacts and Mitigation Strategies
This review examines how micro- and nanoplastics in aquatic environments are biologically transferred up the food chain, covering the factors that influence particle bioavailability, accumulation in organisms, and trophic transfer — with implications for both aquatic ecosystem health and human dietary exposure.
Microplastic in freshwater ecosystem: bioaccumulation, trophic transfer, and biomagnification
This review synthesizes evidence on microplastic bioaccumulation and trophic transfer in freshwater ecosystems, finding that while ingestion by freshwater organisms is well-documented, biomagnification through food chains remains poorly understood and requires further investigation.
Infiltration of freshwater food chain by nanoplastics: An examination of trophic transfer and biological impact
Researchers used fluorescent nanoplastics to track how these particles move through a freshwater food chain from algae to water fleas. They found that nanoplastics accumulated more in water fleas through the food chain than through direct water exposure, with positively charged particles infiltrating more readily. The study suggests that foodborne nanoplastic exposure may be a more significant pathway for contamination in aquatic ecosystems than waterborne exposure alone.
Uptake and Transfer of Polyamide Microplastics in a Freshwater Mesocosm Study
A freshwater mesocosm study tracked the trophic and ontogenetic transfer of polyamide microplastics through an aquatic food web under near-natural conditions, confirming that particles were transferred between prey and predators at multiple levels. The results demonstrate that microplastic transfer through food webs occurs in realistic community settings, not just isolated laboratory tests.
Trophic transfer of nanomaterials and their effects on high-trophic-level predators
Researchers reviewed 15 years of research on how nanomaterials — including metal-based particles, carbon materials, and nanoplastics — transfer through aquatic and terrestrial food chains, finding that particle-specific transfer factors better capture their movement and that trophic transfer causes measurable toxicity at molecular, physiological, and population levels in predators.
Mass-based trophic transfer of polystyrene nanoplastics in the lettuce-snail food chain
Researchers traced the trophic transfer of polystyrene nanoplastics from water into lettuce plants and then into garden snails, finding measurable mass-based transfer at each step of the food chain even at low nanoplastic concentrations using pyrolysis-GC/MS quantification.
Trophic transfer and individual impact of nano-sized polystyrene in a four-species freshwater food chain
Researchers traced nano-sized polystyrene plastics through a four-species freshwater food chain — from algae to water fleas to two fish species — finding that nanoplastics transferred at each level and caused reduced activity, liver damage in fish, and penetration into fish embryos. The results highlight the broad ecological and health risks of nanoplastics moving up through aquatic food webs.
Tracking nanoplastics in freshwater microcosms and their impacts to aquatic organisms
Researchers tracked palladium-doped polystyrene nanoplastics in freshwater microcosms and found they caused toxic effects on cyanobacteria, green algae, and crustaceans at varying concentrations, with particle aggregation and surface interactions driving organism-specific impacts.
How Do Microplastics Distribute Through Freshwater Ecosystems? Which Biota, Feeding Groups, and Trophic Levels Are Most at Risk?
This review examines how microplastics distribute through freshwater ecosystems — across water columns, sediments, biota, and trophic levels — identifying filter feeders, detritivores, and higher trophic level organisms as particularly vulnerable to microplastic accumulation.
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.
Core–Shell Au@Nanoplastics as a Quantitative Tracer to Investigate the Bioaccumulation of Nanoplastics in Freshwater Ecosystems
Researchers developed a novel gold-core/polystyrene-shell nanoparticle tracer that mimics nanoplastic behavior in freshwater but can be detected and quantified far more precisely using the gold core's chemical signature. Using this tracer in artificial freshwater mesocosms, they tracked how nanoplastics distribute across water, sediment, and organisms — providing a powerful new tool to study nanoplastic fate and bioaccumulation.
Tracking the micro- and nanoplastics in the terrestrial-freshwater food webs. Bivalves as sentinel species
Researchers tracked the transfer of micro- and nanoplastics through an experimental terrestrial-freshwater food chain involving earthworms, freshwater mussels, and predatory fish. The study found evidence of trophic transfer of plastic particles across species, with bivalves serving as effective sentinel organisms for monitoring plastic contamination in freshwater ecosystems.
From the synthesis of labeled nanoplastic model materials (isotopic and metallic) to their use in ecotoxicological studies with the detection and quantification analytical methods.
This study developed labeled nanoplastic model materials using isotopic and metallic tracers to enable tracking and quantification of nanoplastics in complex biological and environmental matrices at environmentally relevant concentrations. Labeled particles allowed localization and measurement of nanoplastics at levels not detectable by conventional methods, advancing mechanistic exposure studies.
Quantitative tracking of nanoplastics along the food chain from lettuce (Lactuca sativa) to snails (Cantareus aspersus)
Researchers tracked the transfer of nanoplastics through a terrestrial food chain from lettuce to snails using specially labeled particles. They confirmed that nanoplastics taken up by lettuce were transferred to snails that fed on the contaminated plants, with measurable accumulation in snail tissues. The study provides direct evidence that nanoplastics can move up the food chain through trophic transfer in land-based ecosystems.
Microplastic pollution: exploring trophic transfer pathways and ecological impacts
Researchers reviewed how microplastics — tiny plastic fragments under 5 mm — move through food chains across aquatic and terrestrial ecosystems, turning up in everything from table salt and drinking water to fish and earthworms. The review highlights how microplastics disrupt nutrient cycling and accumulate across trophic levels, calling for stronger management strategies to curb this global pollutant.
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.
The significance of trophic transfer of microplastics in the accumulation of plastic additives in fish: An experimental study using brominated flame retardants and UV stabilizers

Uptake, removal and trophic transfer of fluorescent polyethylene microplastics by freshwater model organisms: the impact of particle size and food availability
Researchers used fluorescent polyethylene microplastics of different sizes to track how they move through a freshwater food chain from algae to water fleas to zebrafish. They found that smaller particles were ingested and transferred more readily between organisms, and that food availability influenced how many microplastics accumulated. The study demonstrates that microplastics can move up the food chain and that particle size plays a key role in how they are transported through aquatic ecosystems.
