Additional data for "Settling Velocities of Small Microplastic Fragments and Fibers"
AI summary Read the abstract
This data repository provides raw settling velocity measurements for small microplastic fragments and fibers, supporting a publication on their transport behavior in water. Settling velocity data is critical for modeling where microplastics deposit in rivers, lakes, and ocean sediments.
Improved Settling Velocity for Microplastic Fibers: A New Shape-Dependent Drag Model
AI summary Read the abstract
A new shape-dependent drag model was developed to improve the accuracy of settling velocity predictions for microplastic fibers, addressing a major limitation of existing drag models that significantly underpredict fiber settling in aquatic environments.
Settling velocity of submillimeter microplastic fibers in still water
AI summary Read the abstract
The settling velocity of 519 submillimeter microplastic fibers (300-600 micrometers long) was measured in still water, finding that settling rates vary considerably by fiber length and orientation, informing models of microplastic fiber transport and deposition in aquatic systems.
Settling Velocities of Small Microplastic Fragments and Fibers
AI summary Read the abstract
Researchers precisely measured the settling speeds of over 4,000 small microplastic particles in water and found that existing prediction models designed for larger microplastics do not work well for these tiny fragments and fibers. The settling speed depends on each particle's size, density, and shape, with the smallest particles sinking extremely slowly. Understanding how quickly microplastics settle in water is important because it determines how far they travel and how long they remain available to be consumed by aquatic organisms that humans may eventually eat.
A new model for the terminal settling velocity of microplastics
AI summary Read the abstract
A new empirical model for the terminal settling velocity of microplastics was developed and validated using 1,343 experimental measurements covering a range of particle shapes and materials. The model improves predictions of microplastic sedimentation rates, which are critical for understanding how plastic particles are transported and deposited in water bodies.
