Microplastic transport in groundwater: A review of Pore-Scale Transport Mechanisms
Microplastics are plastic polymer particles ranging from approximately 1 μm to 5 mm in size. The most common polymer types include polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene terephthalate (PET) (Huang et al., 2021). These particles are primarily generated through the fragmentation and degradation of larger plastic debris exposed to physical, chemical, and biological weathering processes (Walker & Fequet, 2023). To date, microplastics...
