This paper presents a high-resolution model predicting microplastic masses in Swiss river networks for seven polymers. The model couples microplastic release and fate models, revealing that catchment characteristics (release distribution, lake presence, river connections) are crucial for microplastic transport, alongside polymer properties like density. Results highlight the importance of spatially distributed release data and high-resolution modeling for accurate microplastic estimations in large areas.
