‘The Great River Thames Washout’: The Impact of Seasonality on Microplastic Abundance
AI summary Read the abstract
Researchers monitored microplastic abundance in the River Thames across seasons, finding that flow rates and rainfall patterns significantly influence particle concentrations and distribution in UK river systems. The study highlights a regulatory blind spot -- microplastics are not yet monitored as part of official UK water quality testing -- leaving the public without systematic data on their exposure through river environments.
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.
A Review of Microplastics in Aquatic Sediments: Occurrence, Fate, Transport, and Ecological Impact
AI summary Read the abstract
Researchers reviewed how microplastics accumulate in aquatic sediments — particularly the ocean floor — finding that sediments act as a long-term sink where plastics alter microbial communities and harm bottom-dwelling organisms, meaning the ecological damage of plastic pollution extends far beyond what is visible at the water surface.
Large microplastic particles in sediments of tributaries of the River Thames, UK – Abundance, sources and methods for effective quantification
AI summary Read the abstract
Researchers surveyed sediments from tributaries of the River Thames and found large microplastic particles — fragments and pellets — with concentrations reflecting proximity to urban areas and historical plastic use patterns.
Abundance of microplastics in sediments from the urban river in Mongolia
AI summary Read the abstract
This study quantified microplastic concentrations in sediments of the Tuul River in Ulaanbaatar, Mongolia, finding an average of 603 ± 251 items/kg across six sampling sites. Synthetic fibers of polyester and polyamide dominated, with finer sediment particles associated with higher MP counts, and wastewater treatment plant proximity correlating with elevated concentrations.
