ClearTransfer of Polystyrene Microplastics with Different Functional Groups in the Aquatic Food Chain
Researchers investigated how polystyrene microplastics with different surface functional groups accumulate and transfer through an aquatic food chain, finding that surface chemistry significantly influences microplastic uptake and trophic transfer between organisms.
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.
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.
Relative importance of microplastics as a pathway for the transfer of hydrophobic organic chemicals to marine life
Researchers assessed the relative importance of microplastics as a pathway for transferring hydrophobic organic chemicals to marine life. The study suggests that while microplastics can carry high concentrations of contaminants, factors like gut surfactants, pH, and temperature influence desorption rates, and modeling indicates other exposure routes may be more significant in natural environments.
Trophic transfer of nanoplastics through a microalgae–crustacean–small yellow croaker food chain: Inhibition of digestive enzyme activity in fish
Researchers tracked how nanoplastics move through a marine food chain from microalgae to crustaceans to fish, demonstrating that plastic particles transfer upward through feeding relationships. The nanoplastics accumulated at each level and ultimately inhibited digestive enzyme activity in the fish. The study suggests that nanoplastics could eventually reach humans through seafood consumption via this same trophic transfer process.
Trophic transfer of nanoplastics reduces larval survival of marine fish more than waterborne exposure
This study compared direct waterborne exposure versus trophic transfer of micro- and nanoplastics on marine fish larvae, finding that trophic transfer caused significantly higher larval mortality. The results suggest that dietary uptake through the food web is a more dangerous exposure route than direct water contact for early-stage fish.
Microplastics as vectors for bioaccumulation of hydrophobic organic chemicals in the marine environment: A state-of-the-science review
This state-of-the-science review examined whether microplastics serve as vectors for bioaccumulation of hydrophobic organic chemicals in marine organisms. The study found that while microplastics can carry high concentrations of sorbed chemicals, their relative importance as an exposure route compared to other pathways like water and food remains an active area of research with varying conclusions depending on environmental conditions.
Effects of nanoplastics on microalgae and their trophic transfer along the food chain: recent advances and perspectives
This review summarized evidence on how nanoplastics affect microalgae — including growth inhibition, oxidative stress, and altered photosynthesis — and examined trophic transfer of nanoplastics up the food chain, finding that toxicity depended on NP concentration, size, and surface charge.
Important 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.
Distribution, bioaccumulation, and trophic transfer of palladium-doped nanoplastics in a constructed freshwater ecosystem
Researchers used palladium-doped nanoplastics as tracers in a constructed freshwater ecosystem to quantitatively track distribution, bioaccumulation, and trophic transfer, finding that nanoplastics move through multiple trophic levels and accumulate in organisms.
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.
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.
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.
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 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.
Trophic transfer of nanoplastics reduces larval survival of marine fish more than waterborne exposure
Researchers compared the effects of waterborne versus trophic (food chain) exposure to microplastics and nanoplastics on larvae of red sea bream and found that trophic transfer reduced larval survival more severely than direct waterborne exposure. The results underscore the importance of dietary exposure pathways in assessing nanoplastic risk to marine fish.

Trophic transfer of microplastics in aquatic ecosystems: Identifying critical research needs
This review analyzed the available literature on trophic transfer of microplastics in aquatic food webs, identifying key factors — particle size, shape, density, and organism feeding behavior — that determine whether microplastics pass through organisms or accumulate. The authors conclude that biomagnification of microplastics remains poorly understood and requires targeted research.
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.
