Microplastics in River Sediments Nearby to a Sewage Treatment Plant: Extraction, Processing and Characterization Assessment
AI summary Read the abstract
Researchers developed and assessed methods for extracting, processing, and characterizing microplastics from river sediments near a sewage treatment plant, documenting pollution levels and particle characteristics. Rivers act as both sinks and transport corridors for microplastics from wastewater discharge, making robust sediment sampling methods essential for tracking pollution sources and protecting downstream aquatic food webs.
Microplastic pollution is an emerging concern for the aquatic environments as it has been reported in many rivers, lakes, reservoirs and aquatic organisms around the globe. Rivers behave as a temporary sink for microplastics and also serve as a medium through which...

Microplastic Pollution in Freshwater Sediments: Abundance and Distribution in Selangor River Basin, Malaysia
AI summary Read the abstract
Researchers sampled 25 sites along the Selangor River Basin in Malaysia and found microplastics in every sediment sample, with concentrations of 10–55 particles/kg dominated by small black polypropylene and polyester beads from residential, agricultural, and industrial sources. The findings confirm that freshwater river basins are significant reservoirs of microplastic pollution, highlighting the need for monitoring and mitigation beyond ocean-focused research.

Understanding Microplastic Pollution in Riverbed Sediments: Special Emphasis on a Medium-Sized City in the State of São Paulo, Brazil
AI summary Read the abstract
Sediment samples from an urban stream in Rio Claro, Brazil showed microplastic concentrations up to 18,000 units per kilogram — among the highest reported in Brazil — with fibers and tire wear particles as the dominant types, driven by untreated sewage and stormwater runoff. The extreme pollution levels in a mid-sized city highlight that microplastic contamination is not confined to megacities, posing risks to water quality in smaller urban centers.
