Microplastics: What Can We Learn from Clastic Sediments?
AI summary Read the abstract
An interdisciplinary review compared microplastics to natural clastic sediments, drawing on decades of sedimentology research to better understand microplastic transport, deposition, and environmental fate. Applying established sediment science frameworks to microplastics research could accelerate understanding of how these particles move through ecosystems and ultimately reach human food and water supplies.
Sedimentary records of microplastic pollution from coastal Louisiana and their environmental implications
AI summary Read the abstract
Sediment cores from two coastal Louisiana estuaries revealed microplastic fibers, fragments, and sheets accumulating in the sedimentary record, with concentrations highest near the surface and declining with depth. The presence of trace microplastics even in pre-1950 sediment layers — likely from bioturbation — highlights how these pollutants become embedded in coastal ecosystems, creating long-term exposure risks for benthic organisms.
Research Progress on Sources and EcologicalEffects of Microplastics in Sediments
AI summary Read the abstract
This review synthesizes research on the sources and ecological effects of microplastics in sediments, tracing transport pathways from terrestrial runoff through freshwater systems to marine sediment sinks and documenting impacts on benthic organisms and ecosystem function. Sediments serve as long-term reservoirs of microplastic pollution, making sediment ecology a critical lens for understanding cumulative environmental burden and food chain exposure risks posed by plastic debris.
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.
Microplastic Pollution in Freshwater Sediments: Spatial–Temporal Patterns
AI summary Read the abstract
This global review of freshwater sediment studies finds that human activities, stormwater runoff, water flow, and sediment grain size all shape where microplastics accumulate in rivers and lakes, but most data come from Asia with limited coverage elsewhere. Filling these geographic and temporal gaps is essential for understanding the long-term fate of microplastics in freshwater systems that supply drinking water worldwide.
