The Role of Microplastics’ Size and Density on Their Vertical Turbulent Mixing and Transport
AI summary Read the abstract
The size and density of microplastics are key determinants of their vertical mixing and transport dynamics in aquatic environments, influencing how deeply they penetrate water columns. Understanding these physical transport mechanisms is crucial for predicting where microplastics accumulate and assessing exposure risks for aquatic life and human water sources.
Plastic production has increased drastically during the last decade, which has led to a proportional increase in plastic waste generation. Mismanaged plastic wastes enter the aquatic environments through pathways such as rivers, wastewater treatment systems, and...
