Plastics in inland waters: pathways and impact

Plastic pollution is mainly recognized in the oceans, but i relevant also in rivers, estuaries, lakes and wetlands. Composition of plastic debris, transport pathways and interaction with biota show similarities, but also important differences to marine systems, which are not yet well understood. Knowledge gaps result, among others, from inconsistent monitoring or sampling strategies and geographic bias. We therefore encourage presentations covering systematic assessments of all sizes of plastic in inland water systems, observations related to extreme weather or pandemic, and studies at the freshwater-ocean or freshwater-terrestrial interface. Moreover, plastic interactions with water-associated biota beyond ingestion will be of special interest.
