Microplastic and Silica Colloid Transport in a Saturated Porous Medium Under Various Flow Directions: the Effect of Gravity
AI summary Read the abstract
Lab column experiments showed that gravity and flow direction significantly affect how microplastic and silica microspheres are transported and retained in saturated sandy media, with upward flow causing roughly twice the particle deposition compared to downward flow. Understanding these transport dynamics is essential for predicting how microplastics spread through groundwater systems and ultimately reach drinking water sources.
Transport Process of Microplastics from Terrestrial to Aquatic Environment: Evaluation of the Current Knowledge
AI summary Read the abstract
Researchers reviewed how microplastics travel from terrestrial sources — including agriculture, urban runoff, and atmospheric deposition — into rivers, lakes, and ultimately the ocean, synthesizing current knowledge on transport mechanisms and knowledge gaps. Understanding land-to-water transport pathways is critical for identifying where interventions can most effectively reduce the flow of plastics into aquatic ecosystems and human food sources.
Evaluating Macroplastics Transport Thresholds for Overland Flow Processes
AI summary Read the abstract
Researchers ran controlled flume experiments with six plastic bottle types across surfaces mimicking roads, deteriorated pavement, and vegetated swales, revealing a two-stage transport process in which plastics begin moving at lower flows but require substantially higher flows for full displacement—with density, shape, and cap orientation creating nonlinear relationships between flow strength and travel distance that simple mass or discharge metrics cannot predict.
Insights on experimental methodologies and theoretical models for microplastics transport in soils and sediments based on meta-analysis
AI summary Read the abstract
"A meta-analysis of experimental methods and mathematical models for microplastic transport in soils found that available experiments mainly simulate shallow beach sand, leaving transport in agricultural soils, sediments, and landfill liners largely unstudied, and that a dual-site advection-dispersion model best fits existing data. Accurate transport models are essential for predicting how microplastics migrate toward groundwater and food crops, which directly informs human exposure risk assessment."
Experimental study on transport processes of fragment microplastics during urban road rainfall runoff
AI summary Read the abstract
Tiny plastic fragments that accumulate on roads get swept into rivers and lakes when it rains, especially during heavy storms, on flatter roads, and when smaller fragments are involved, according to this study. This matters because these plastics eventually end up in the water bodies that supply our drinking water and support fish and wildlife, and understanding how rain washes them away can help cities design better filtering systems to catch them before they spread further into the environment.
