Interaction of Microplastics with Trace Metals and Bacteria, and Potential Impacts on Fish

Microplastics' abundance in the aquatic environment have been documented numerously, nevertheless their associated chemical and biological hazards are somewhat understudied. This research therefore aimed to assess the interactions of microplastics with trace metals and bacteria in the aquatic ecosystem; and risks they pose to fish upon ingestion. Results showed successful attachment of both components to microplastic surfaces; and were efficiently transferred to fish. This research highlighted potential risks microplastics pose to aquatic environment; by acting as sinks, dispersal means, as well as shuttles for contaminants transfer to ingesting organisms which leads to bioaccumulation and potential toxicity.
