Factsheet 7.1: Microplastics around dams - How do plastic particles behave in reservoirs?
Plastic is now ubiquitous not only in the sea but also in many inland waters. In certain areas, such as at barrages or in dams, the flow velocity decreases. As a result, the particles previously held in suspension by the current begin to sink to the bottom of the water and can then accumulate in the sediment.
