Soils have been identified as a major sink for plastics which has led to increasing concerns for essential soil ecosystem services. However, we still lack an in-depth understanding of transport processes and the fate of macro-, micro-, and nanoplastics in the terrestrial environment. In this session, we invite contributions that present empirical, monitoring, and modelling studies for all scales of plastic pollution and soil systems, advancing our mechanistic understanding of transport and fate in the terrestrial environment. This includes but is not limited to urban settings, agroecosystems, and soil interfaces between different environmental compartments. Presentations may focus on:
• Experimental studies at different scales (lab, mesocosm, field, etc.) advancing our process-based understanding of transport and transformation processes
• Monitoring efforts to understand source attribution and quantification of spatiotemporal trends in inputs, releases, and transfers
• Models addressing fate and transport processes within terrestrial environments and their interfaces, such as connected aquatic and atmospheric systems
• Human behaviour, littering and littering dynamics, urban drainage systems, and solutions
