Settling and Rising Hydrodynamics of Microplastic Pollutants: A Numerical Study

Lecture notes in civil engineering 2023
Zihe Zhao, Shooka Karimpour

Summary

Using numerical hydrodynamic modeling, researchers investigated how microplastics of varying shapes, densities, and sizes settle and rise through aquatic environments, revealing complex transport behaviors that differ substantially from natural particles. Understanding these movement dynamics is essential for predicting where microplastics accumulate in water bodies, informing risk assessments for aquatic organisms and the design of effective removal strategies.

With ever-growing plastic production, the pollution of microplastics (MPs) has become a threatening environmental problem in the twenty-first century. It is crucial to investigate MPs’ hydrodynamics due to their widespread pollution in aquatic environments. MPs...
