ClearOccurrence and spatial distribution of microplastics in sediments from Norderney
Researchers surveyed sediments from Norderney in the North Sea and found widespread microplastic contamination, documenting spatial distribution patterns and particle characteristics across this tidally influenced coastal environment.
Assessment of marine debris on the Belgian Continental Shelf
Researchers assessed marine debris across beach, sea surface, and seafloor compartments of Belgian coastal waters over two consecutive years, finding that plastic items dominated macrodebris at over 95% of all debris by count. Microplastic concentrations were also quantified in all three compartments, revealing consistent contamination across the Belgian Continental Shelf.
Microplastics Baseline Surveys at the Water Surface and in Sediments of the North-East Atlantic
Researchers measured microplastic concentrations at the sea surface and in sediments across the southern North Sea and northwestern Europe, finding highly variable but widespread contamination. Sediments contained far higher concentrations than surface waters, confirming that the seafloor acts as a major sink for microplastic pollution.
Distribution and characterization of microplastics in marine sediments from coastal and offshore in South Korea
Researchers conducted an intensive survey of microplastic levels and distribution in marine sediments from coastal areas, recognizing the seafloor as the ultimate repository for plastic particles. Microplastic concentrations in sediments were highest near urban and industrial coastlines, with fibers and fragments as the most common types.
Microplastics in sea surface waters in the Southern Bight of the North Sea
Researchers quantified floating microplastics in surface waters of the Southern Bight of the North Sea, finding elevated concentrations near the Belgian and Dutch coasts with size and polymer distributions reflecting riverine and shipping inputs.
Occurrence and identification of microplastics in beach sediments from the Hauts-de-France region
Microplastics were found in beach sediments along three sites on the northern French coast, with the most contaminated site near an urban-industrial area. Fragments and films dominated, reflecting local land-based and maritime sources of plastic pollution.
A large-scale investigation of microplastic contamination: Abundance and characteristics of microplastics in European beach sediment
This large-scale investigation characterized microplastic contamination across a wide geographic area, documenting abundance and polymer types and providing a baseline dataset for tracking pollution trends over time.
Ubiquity of microplastics in coastal seafloor sediments
Researchers applied a novel method to quantify microplastic concentrations in seafloor sediments from 42 coastal sites across southeastern Australia. They found microplastics in all samples at an average concentration of 3.4 particles per milliliter of sediment, predominantly as filaments. The study demonstrates that microplastic contamination of coastal seafloor sediments is ubiquitous and that hydrological and sediment properties influence deposition patterns.
Microplastic abundance and characteristics in French Atlantic coastal sediments using a new extraction method
Researchers developed a new extraction method for microplastics from coastal Atlantic sediments in France and applied it to characterize microplastic abundance and composition, finding widespread contamination and demonstrating the method's improved efficiency for recovering particles from sediment matrices.
Spatial distribution of microplastics in sediments and surface waters of the southern North Sea
A systematic survey of microplastic distribution in sediments and surface waters of the southern North Sea found widespread contamination across the region, with spatial patterns reflecting currents, water depth, and proximity to shipping lanes and coastal inputs. The study provides a regional baseline for microplastic pollution in one of the world's busiest shipping and fishing areas.
Microplastics in the Mediterranean Sea: Deposition in coastal shallow sediments, spatial variation and preferential grain size
Researchers sampled Mediterranean coastal shallow sediments and found microplastics throughout, with concentrations and polymer types reflecting land-based inputs and showing that coastal sediments are a significant regional reservoir for plastic debris.
Abundance and characterization of microplastics on sandy beaches along the coastal area of Belize
Researchers quantified and characterized microplastic abundance on sandy beaches along the coastal zone of Belize, establishing baseline contamination data for a region of Central America and the Caribbean where such pollution assessments are critically lacking.
Distribution and characterization of microplastics in marine sediments from the Montenegrin coast
Researchers characterized microplastic distribution in marine sediments along the Montenegrin coast, providing the first assessment of microplastic pollution status in this understudied region of the Adriatic Sea.
The fate of microplastic in marine sedimentary environments: A review and synthesis
A systematic review of 80 papers on microplastics in marine sediments found median concentrations varied widely by sediment environment, with fibers dominating many locations, and showed that sediment grain size and organic carbon content influence microplastic accumulation.
