Microplastics in the environment: Investigations in the Weser catchment

AI summary Read the abstract

This report presents findings from the PLAWES collaborative project estimating the spatial distribution of microplastic inputs across the Weser river basin in Germany. The study assessed contributions from multiple agricultural and urban sources and coordinated findings with a parallel study of the Warnow catchment.

Study Type Environmental

• As part of the collaborative project PLAWES, we estimated the spatial distribution of microplastic inputs in a hydrologically and agriculturally heterogeneous river basin • Through the parallel investigation of two river basins (Weser and Warnow) in cooperation with the MicroCatch_Balt project, the influence of the different land use structures was considered • The results point to strong regional variability with local microplastic concentrations, which should be considered in more detail in subsequent studies • Such an overall view is indispensable in order to assess the scope for policymaking and to develop efficient options for action

Airborne microplastic concentrations and deposition across the Weser River catchment

AI summary Read the abstract

Researchers measured airborne microplastic concentrations and deposition rates across the Weser River catchment in Germany, sampling urban, suburban, and rural locations. They found that microplastics were present in the atmosphere at all sites, with higher concentrations near wastewater treatment plants and urban areas. The study estimates that atmospheric deposition is a meaningful pathway for microplastic contamination of river systems.

Microplastic pollution in the Weser estuary and the German North Sea

AI summary Read the abstract

Microplastics were characterized in water and sediment samples from the Weser estuary and German North Sea coast, with concentrations decreasing offshore and fibers dominating in all matrices, consistent with urban and industrial river inputs as the primary source of coastal North Sea microplastic contamination.
