Quo vadis? Discovering the impact of biofouling on fluvial microplastic transport

    Project: NWO project

    Project Details

    Description

    Accumulation of microplastics (<5mm) in rivers poses a potentially significant environmental risk. To better assess this risk, exposure and impact need to be further investigated. The exposure depends on the transport behavior of microplastics, which is still poorly understood for rivers. Especially the effect of biofouling on the transport of microplastics has not yet been quantified. Through physical experiments we quantify the influence of biofouling on microplastic transport in rivers. This knowledge will be implemented in models that predict microplastic accumulation sites. In doing so, we are taking an important step in mapping the risks of microplastics in rivers.

    Description

    Ophoping van microplastics (<5mm) in rivieren vormt een potentieel groot milieurisico. Om dit risico beter in te kunnen schatten, moeten de blootstelling en impact nader onderzocht worden. De blootstelling hangt af van het transportgedrag van microplastics, wat voor rivieren slecht bekend is. Vooral het effect van biofouling op het vervoer van microplastic is nog niet gekwantificeerd. Middels fysieke experimenten kwantificeren we de invloed van biofouling op microplastic transport in rivieren. Deze kennis wordt geïmplementeerd in modellen die ophooplocaties van microplastics voorspellen. Daarmee zetten we een belangrijke stap in het in kaart brengen van de risico’s van microplastics in rivieren.
