Unveiling historical suspended sediment concentrations: Tracing microplastics and microfibers in a mediterranean lowland river
AI summary Read the abstract
Researchers examined historical suspended sediment samples from a Mediterranean river catchment for microplastics, establishing a baseline of contamination dating back to 2005 and tracking changes over the study period. The retrospective analysis revealed that microplastic concentrations in riverine sediment have increased over time.
This study evaluates microplastics and microfibers in historical suspended sediment samples and their concentrations in fluvial suspended sediment from June 2005 to February 2006 for two nested Mediterranean lowland catchments of the Na Borges basin (319 km2, Mallorca, Spain), a groundwater-dominated river where the surface water/groundwater interaction is controlled by its hydrogeological and geomorphological characteristics and their modification by human impacts. The first study area is Can Revull, a small catchment (1.02 km2) in the headwaters of Na Borges, is predominantly occupied by herbaceous agriculture and subsurface tile drainage (91 Also see: https://micro2024.sciencesconf.org/559537/document

Unveiling historical suspended sediment concentrations: Tracing microplastics and microfibers in a mediterranean lowland river
AI summary Read the abstract
Researchers analyzed historical suspended sediment samples from a Mediterranean catchment in Mallorca collected between 2005 and 2006 for microplastics and microfibers, providing a rare retrospective view of contamination. Microplastics were present even in these older samples, establishing a pre-existing baseline of contamination in the catchment.

Researchers reconstructed the historical trend of microplastic pollution in the Seine River basin from 1960 to 2020 by analyzing sedimentary archives, using sediment cores as long-term records to track how contamination levels have changed upstream of Paris over six decades.
Tracking the microplastic accumulation from past to present in the freshwater ecosystems: A case study in Susurluk Basin, Turkey
AI summary Read the abstract
Researchers tracked the historical accumulation of microplastics in freshwater lake sediment cores, finding a steady increase in particle deposition corresponding to rising plastic production since the mid-20th century and demonstrating that sediment archives can reconstruct the timeline of freshwater microplastic pollution.
Microplastic in sedimentary archives of the Rhône River: a 35-year record of the impact of the Lyon urban area
AI summary Read the abstract
Researchers analyzed microplastic contamination in 35 years of archived sediment cores from the Rhône River near Lyon, France, revealing how plastic pollution has changed over time in one of Europe's largest rivers. This historical record shows how urban industrial activity has shaped the accumulation of microplastics in river sediments over recent decades.
