Modeling the Fate and Transport of Microplastics in Coastal Areas
AI summary Read the abstract
Numerical models can simulate how microplastics move through coastal environments by integrating hydrodynamic, biological, and atmospheric processes, helping predict accumulation hotspots and exposure zones. These modeling tools are vital for guiding cleanup efforts and assessing risks to coastal communities and marine food sources.
Numerical models are strong tools to understand the dynamics better and analyze the sources, transport, receptors, and consequences of microplastics in the coastal environment. Complex dynamics and interactions of biotic and abiotic components of aerial, terrestrial,...

Modeling the Fate of Nano- and Microplastics in freshwater systems
AI summary Read the abstract
Researchers developed a spatially and temporally explicit fate model for nano-, micro-, and millimeter-scale polymer particles in the river Dommel, finding that particle size, biofilm formation, and water turbulence are the dominant controls on retention and downstream transport, with larger particles and biofouled surfaces settling preferentially in specific riverine hot spots.
Tracing the Footprint of Microplastics: Transport Mechanism, Degradation, and Remediation in Marine Environment
AI summary Read the abstract
Researchers synthesized current knowledge on microplastic transport, degradation, and remediation in marine environments, examining how the high surface-area-to-volume ratio of these particles enables them to bind heavy metals, antibiotics, and persistent organic pollutants — amplifying their ecological impact across ocean systems.
Numerical Modeling of Microplastics Fate and Transport in a Stretch of the Fraser River
AI summary Read the abstract
Researchers used numerical modeling to simulate how microplastics move and accumulate within a stretch of the Fraser River, providing predictions of particle fate and transport that can inform where microplastics concentrate and how rivers function as conduits delivering plastic pollution from land to sea.
Transport Mechanism of Microplastic in the Environment
AI summary Read the abstract
This review described the physical and chemical mechanisms by which microplastics are transported through air, water, and soil — including atmospheric deposition, hydrological flow, bioturbation, and biofouling — that collectively explain their detection in remote environments from Arctic sea ice to mountain summits. Elucidating these transport mechanisms reveals that no geographic location or ecosystem is isolated from microplastic contamination, underscoring the inevitability of human exposure through air, water, and food globally.
