Transport Behavior of Microorganisms in Porous Media
Summary
This review synthesizes research on the transport behavior of pathogenic microorganisms through porous media, analyzing the hydrodynamic, hydrochemical, and biological factors governing microbial colloid movement relevant to protecting drinking water resources. The review found that microorganisms behave as biological colloids subject to multiple simultaneous transport mechanisms, with microplastics identified as an additional factor influencing microbial mobility in some contexts.
The study of pathogenic microorganism transport in porous media is of great significance for protecting drinking water resources. On the basis of summarizing existing research data at home and abroad, the transport behavior of microorganisms in porous media was analyzed. Research has shown that pathogenic microorganisms, as a type of biological colloid, are subject to multiple transport mechanisms during their transport process. In addition to common hydrodynamic and hydrochemical conditions, microorganisms are also influenced by their own properties, medium particles, and chemotaxis during transport. This review aims to summarize the relevant research on the transport of microorganisms in porous media in recent years, gain a deeper understanding of the transport behavior of microorganisms in porous media, and provide theoretical basis for their practical application in groundwater and soil pollution remediation.

Microplastics/nanoplastics in porous media: Key factors controlling their transport and retention behaviors
This review examines what controls how microplastics and nanoplastics move through soil and other porous materials like sand and sediment. Factors like particle size, shape, surface charge, water flow speed, and the presence of other pollutants all influence whether plastics stay in place or travel deeper into groundwater. Understanding these transport behaviors is important for assessing the risk of microplastics contaminating underground drinking water sources.
Modeling microplastic transport through porous media: challenges arising from dynamic transport behavior
This perspective article reviews microplastic transport through porous media such as soils and aquifers, identifying the limitations of existing hydrogeological models and proposing research directions for more effectively modelling the dynamic, particle-specific transport behaviour of microplastics in porous environments.
Colloid (Nano- and Micro-Particle) Transport and Surface Interaction in Groundwater
This book examines the field-scale transport and spatial distribution of colloids in groundwater, covering pathogens, clays, nanomaterials, nanoplastics, and microplastics as examples of nano- and micro-particles whose movement through subsurface systems has significant environmental and public health implications.
Key factors controlling transport of micro- and nanoplastic in porous media and its effect on coexisting pollutants
Researchers reviewed the key factors that control how micro- and nanoplastics move through porous media such as soil and sediment, and how they affect the transport of co-occurring pollutants. They found that microplastics can either facilitate or inhibit the movement of other contaminants depending on particle properties and environmental conditions. The review emphasizes the need to better understand these co-transport dynamics for predicting the environmental fate of plastic pollution.
Transport and deposition of microplastic particles in saturated porous media: Co-effects of clay particles and natural organic matter
Researchers performed column experiments to study how clay particles and natural organic matter affect microplastic transport through saturated porous media, finding that both colloids reduced MP mobility through heteroaggregation and that their combined presence produced the greatest reduction in transport.
