This session focuses on the small-scale transport processes of plastic pollution (macro, micro- and nano-plastics) across aquatic environments and groundwaters. While we aim to place special emphasis on laboratory experiments and modelling approaches, we also welcome presentations employing field work, and contributions focused on theoretical concepts.

The presentations will revolve around understanding and characterising plastic movement and distribution, considering governing factors like particle physical characteristics, including size, shape, density, and surface chemistry, as well as environmental conditions such as flow, turbulence, temperature, salinity and suspended sediment. Relevant biological and chemical processes will be taken into account such as biofouling, aggregation and fragmentation, as well as plastic's role as transport vectors for other emerging contaminants, adding to their transport complexity.

Beyond the presentation of research findings, this session will also focus on advancements in laboratory and numerical techniques, highlighting improvements in accuracy, complexity, and spatial-temporal resolution. Cutting-edge modelling approaches tailored to simulate the transport dynamics of plastics in the environments will be showcased.
Through engaging discussions, the session aims to enhance our comprehension and predictive capabilities, while also identifying unresolved questions and paving the way for future research in this field.
