Microplastic in freshwater ecosystem: bioaccumulation, trophic transfer, and biomagnification
AI summary Read the abstract
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.
Plastic wastes in the environment ultimately reach to the aquatic habitats and become available to aquatic organisms. The pathway of microplastic in aquatic ecosystem is very less investigated specially in freshwater. There have been evidences of MPs ingestion by freshwater biota but the fate of these MPs further in the food chain is unexplored. Thus, we reviewed the status of MPs in freshwater biota and tried to compare the studies to merge the available information, concepts, and perspectives in order to draw a conclusion on bioaccumulation potential, trophic transfer possibilities, biomagnification, and trends of ingesting MPs by the biota. In this review, the previously available information about MPs in aquatic biota is arranged, analyzed, and interpreted to understand all possible routes of MPs in freshwater habitats. The review further provides a better understanding about the lack of information and research gaps that are needed to be explored to develop a solution to the problem of MPs in near future.

Gathering at the top? Environmental controls of microplastic uptake and biomagnification in freshwater food webs
AI summary Read the abstract
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
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.
