Predator traits influence uptake and trophic transfer of nanoplastics in aquatic systems–a mechanistic study
AI summary Read the abstract
Researchers investigated how predator feeding behaviors — such as filter feeding versus active hunting — influence how much nanoplastics (plastic particles smaller than 1 micrometer) are taken up and passed up the food chain in aquatic ecosystems. Understanding these pathways matters because nanoplastics consumed by small aquatic animals can accumulate in larger predators, including fish eaten by humans.

Trophic transfer of microplastics in aquatic ecosystems: Identifying critical research needs
AI summary Read the abstract
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.
Important ecological processes are affected by the accumulation and trophic transfer of nanoplastics in a freshwater periphyton-grazer food chain
AI summary Read the abstract
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.
Trophic transfer of nanomaterials and their effects on high-trophic-level predators
AI summary Read the abstract
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.
Micro-Nano Plastics in Aquatic Environments: Associated Health Impacts and Mitigation Strategies
AI summary Read the abstract
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.
Ingestion and transfer of microplastics in the planktonic food web
AI summary Read the abstract
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.
