Fate of Microplastic in Freshwater Ecosystem: Bioaccumulation, Trophic Transfer and Biomagnification

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
