The aim of MOTION is to improve understanding of particle aggregation behavior and the role of biofilms for the assessment of microplastic impact in the Baltic Sea.

Why is it important?

Assessing the impacts of plastic litter is crucial for developing adequate management strategies. To assess interactions between biota and plastic microlitter and to predict microplastic uptake and colonization by microorganisms, we need to better understand the mechanisms of aggregation and their behavior in the water. MOTION is a collaboration physical oceanographers from the Shirshov Institute of Oceanology, who are experts in the field of modeling microplastic distribution and transport, and Department of Environmental Science, Stockholm University, who are experts in biological oceanography and plankton ecology.

Perspectives

Protecting marine environment from litter pollution requires understanding of its hazard nature and predicting the outcomes. These aspects are currently very unclear, which hampers development of an adequate approach for risk assessment of microplastics. A crucial issue for the hazard assessment is aggregation and sedimentation of microplastic in the water column, because it affects encounter rate and local accumulations of microplastic in the marine environment.
