Oct 20, 2019 · Microplastics, as exogenous particles with a hydrophobic surface, are highly likely to provide new substrates for heterotrophic microbial activities (Arias-Andres et al., 2018), making their surface microbial communities significantly different from those of the surrounding environment and other organic residues (McCormick et al., 2014; Dussud ... Microplastics also pose a greater risk in urban rivers due to a lower volume of water that dilute the plastics.

Wastewater and drinking-water treatments are highly efficient in getting rid of microplastics. Studies, albeit limited, show they remove more than 90% of microplastics. But there is a lot that individuals can do to reduce microplastics too. Perhaps the most important step lies in changing the way we think and behave.
