Research topic

Microplastic as a emerging pollutant recently gained much attention in science and society. Much research efforts were regarded to microplastics in the open oceans. In contrary the aquatic ecosystems and in particular the transport mechanisms of microplastic from rivers to lakes/reservoirs to the sea have not yet been described sufficiently.

Compared to rivers the flow regime in lakes is reduced, leading to a prolonged residence time in the water body. This may increase the extent of biofouling and complexing mechanisms readily removing buoyant particles from the water-column. Therefore lakes are considered to be major sink for microplastic in the aquatic environment.

The project “MikroPlaTas” shall provide more profound knowledge, regarding spatial distribution, composition and concentration of microplastic in different german reservoirs and lakes. In addition the mechanisms governing the sedimentation and movement of microplastic particles in stratified lakes will be investigated.Special emphasis is given to the interaction of microplastic with microorganism of the biogeochemical iron cycle and their behavior under changing redox conditions.
