PaintSed: Farbpartikel in Meeressediment: Wechselwirkungen mit Mikrobiota und Auswirkungen auf Sedimentprozesse

Paint particles are an important and growing pollution in marine systems. Despite being included under the remit of microplastics, and the considerable amount of resarch dedicated to microplastic pollution, paint particle pollution remains notably under-researched and poorly understood. Recent resarch by Tagg et al. demonstrated paint particles in Baltic marine sediment have a fundamentally distinct biofilm community from not only sediment or water, but also other, more traditional, microplastics. It was also noted by Tagg et al. that certain paints demonstarted a clear pattern of sulfate-reducing bacteria enrichment, although the reason for this could not be determined. Using these findings as a starting point, the PaintSed project aims to determine which attributes (especially focussing on aintifouling properties) of certain paints are behind fundamental changes to microbial communities in Baltic Sea sediment.
