This session focuses on the transport, occurrence and fate of plastic pollution (macro-, micro- and nano-plastics) across aquatic environments, soil and groundwater. 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 size, shape, density, and 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 in subsurface environments, adding to their transport complexity and substantially impacts the health of subsurface environments.

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 intricate transport dynamics of plastics in the environment 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 endeavors in this vital area of study.
