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.
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 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.
Microplastics in sediments of Santa Teresa water reservoir (Salamanca, Spain): methodology and sources.
AI summary Read the abstract
Researchers extracted and characterized microplastics from sediment cores of a Spanish water reservoir, finding particles distributed throughout the depth profile at concentrations that increased toward the surface. The study links microplastic accumulation patterns to pollution history and seasonal hydrological dynamics affecting how particles are deposited and preserved.
Spatio-temporal distribution of microplastics in a Mediterranean river catchment: The importance of wastewater as an environmental pathway
AI summary Read the abstract
Microplastic concentrations were mapped across a Mediterranean river catchment in central Spain over multiple seasons, finding that wastewater treatment plant effluents were the dominant point source and that storm events transiently increased concentrations in downstream reaches by mobilizing accumulated particles from river beds and floodplains.
