Fate of Microplastic in Freshwater Ecosystem: Bioaccumulation, Trophic Transfer and Biomagnification
AI summary Read the abstract
This review examined the fate of microplastics in freshwater ecosystems, focusing on bioaccumulation, trophic transfer, and biomagnification pathways. It highlighted major knowledge gaps in freshwater systems compared to marine environments.
Abstract Plastic wastes in the environment ultimately reach to the aquatic habitats and becomes available to aquatic organisms. The pathway of microplastic in aquatic system is very less investigated specially in freshwater systems. 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 available 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 route 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 investigated further to develop a solution to problem of MPs in 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.
Prevalence, Fate and Effects of Plastic in Freshwater Environments
AI summary Read the abstract
This review summarizes the prevalence, environmental fate, and biological effects of plastics in freshwater ecosystems, an area that has received less attention than marine plastic pollution. Freshwater bodies are major pathways for microplastics to reach marine environments and are themselves affected by plastic contamination.
