Transport of microplastic in porous media
AI summary Read the abstract
This bachelor's thesis reviews the transport of microplastic particles through porous media and groundwater, summarizing column experiment methodology, mathematical transport models, and factors affecting particle mobility. Key gaps identified include a lack of field data, oversimplified numerical models, and few experiments under conditions approaching real environmental complexity.
The issue of microplastics, as a widespread and poorly degradable type of waste burdening the environment, has attracted significant attention in recent years. While many studies focus on microplastics, their occurrence and transport in porous media, and thus in groundwater are often overlooked. This review-based bachelor's thesis therefore aims to summarize the available literature concerning the mobility of microplastic particles in porous environments. The thesis presents methodology of column experiments, which represent a key method for studying particle movement through porous materials. It also describes the main mathematical models commonly used to simulate particle transport and retention, as well as their implementation in computer simulations. The following section evaluates the influence of microplastic particle properties and environmental characteristics on particle mobility, with an emphasis on quantifying these effects. The concluding summary assesses the scope of existing studies on the topic, as well as the remaining gaps in research such as the lack of field data, the omission of numerous processes in numerical models, and the scarcity of experiments conducted under conditions approximating the complexity of real environments. In doing so, the thesis also outlines opportunities...

Microplastics/nanoplastics in porous media: Key factors controlling their transport and retention behaviors
AI summary Read the abstract
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.
