This review examined the trophic transfer and accumulation of microplastics through freshwater food chains, highlighting the risks to food security and human health as plastic particles biomagnify from lower to higher trophic levels.
Gathering at the top? Environmental controls of microplastic uptake and biomagnification in freshwater food webs
This review examines the uptake and potential biomagnification of microplastics through freshwater food webs, from primary producers to top predators. Researchers found that while microplastics accumulate in organisms at multiple levels of the food chain, evidence for true biomagnification remains limited and inconsistent. The study identifies key environmental and physical factors that control microplastic exposure pathways and calls for more standardized field studies to resolve whether microplastics concentrate up the food chain.
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.
Impacts of Microplastics as Contaminants in Freshwater Ecosystems and Human Food Chain
