ClearDistribution 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.
Spatial distribution of microplastics in Persian Gulf marine environments
A spatial survey of microplastics in Persian Gulf marine sediments found widespread contamination, with concentrations varying by location and depth. The study adds to evidence that the Gulf's semi-enclosed, heavily trafficked waters are a significant repository for microplastic pollution.
Small plastic debris in sediments from the Central Adriatic Sea: Types, occurrence and distribution
Microplastic debris was found in all sediment samples collected along a 140 km transect in the central Adriatic Sea, including in deep offshore sediments. The study is one of the first to systematically document microplastic distribution along a coast-to-open-sea gradient in this region.
Occurrence 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.
Microplastics in inland and offshore sediments in the Apulo-Lucanian region (Southern Italy)
Microplastics were detected in both inland river sediments and offshore continental shelf sediments in southern Italy, with characterization revealing diverse polymer types and morphologies reflecting both local and transported sources.
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.
From inshore to offshore: distribution of microplastics in three Italian seawaters
Researchers surveyed microplastic concentrations across coastal to offshore areas in three Italian seas, finding heterogeneous distributions of 6,069 particles with differences between surface and subsurface water layers, providing data to support EU marine monitoring programs.
Factors influencing the occurrence and distribution of microplastics in coastal sediments: From source to sink
Researchers sampled microplastics from sediments of two semi-enclosed bays and two coastal open zones in China, finding that proximity to human activity and reduced hydrodynamic energy were the primary drivers of higher microplastic abundance, with Jinghai Bay showing the greatest contamination due to its enclosed geometry and adjacent urban inputs.
Micro- and mesoplastics in sea surface water from a Northern Adriatic coastal area
Researchers collected plastic particles from two sea surface monitoring transects near the Venice Lagoon using a manta net and characterized them by typology, dimension, color, spatial density, and chemical composition using a multi-technique analytical approach. They identified distinct subgroups of plastic micro-debris in this Northern Adriatic coastal area and documented the widespread presence of polymeric materials in surface seawater.
Occurrence and distribution of microplastics in marine sediments along the Belgian coast
Researchers surveyed marine sediments along the Belgian coast and found microplastics distributed across all sampled sites, documenting their occurrence and characteristics in this heavily trafficked North Sea coastal environment.
The distribution of sediment microplastics assemblages is driven by location and hydrodynamics, not sediment characteristics, in the Gulf of Maine, USA
Microplastics were extracted and characterized from 20 sediment samples across the Gulf of Maine and 27 polymer types were identified, with spatial distribution driven more by location and hydrodynamics than by local sediment grain size or composition.
Microplastic Distribution in Sediments in Coastal of Pariaman City, West Sumatera Province
Indonesian researchers surveyed microplastic distribution in sediments along the coast of Pariaman City, West Sumatra, finding plastic particles throughout the study area. Higher concentrations near tourism areas and residential zones suggest that local human activities are the primary sources of coastal microplastic contamination.
Type and Distribution of Microplastic Contamination in Beach Sediment Along the Coast of the Lower Gulf of Thailand
Microplastic contamination was surveyed at five beaches along Thailand's lower Gulf Coast, with Talo Kapo showing the highest abundance and fragment-type particles being most common. The findings document baseline plastic pollution levels and polymer types across different coastal settings.
Occurrence and distribution of microplastics in surface sediments from the Gulf of Thailand
Researchers investigated the distribution and characteristics of microplastics in surface sediments across the Gulf of Thailand, finding an average abundance of 150.4 pieces/kg dry weight with fragment shapes dominating, and observed a correlation between sediment grain size and microplastic content. The results establish baseline contamination data for this Southeast Asian coastal region.
Microplastics spatiotemporal distribution and variability in marine habitats along the North-Western Mediterranean coastal waters.
Researchers mapped microplastic distribution across multiple marine habitat types along the Mediterranean coast, examining spatial and temporal variability from the water surface to the sediment. The study revealed that microplastic abundance and composition differ substantially by habitat, underscoring the need for multi-compartment monitoring.
Contamination and characterization of microplastics in different sediments of the river estuaries (the inner Gulf of Thailand)
Researchers measured microplastic contamination in river estuary sediments in the inner Gulf of Thailand, finding widespread contamination at all sites. The study characterizes the types and abundance of microplastics in a highly trafficked coastal region of Southeast Asia.
Microplastics spatiotemporal distribution and variability in marine habitats along the North-Western Mediterranean coastal waters.
Researchers assessed microplastic spatiotemporal distribution across multiple Mediterranean marine habitat types including water surface, sediment, and biota, revealing significant variability by location and season. The multi-compartment approach showed that no single habitat type captures the full extent of microplastic contamination.
Macrodebris and microplastics from beaches in Slovenia
Researchers surveyed both macrodebris on beaches and microplastics in shoreline and sublittoral sediments in Slovenia, providing the first such dataset for this short Adriatic coastline. The study found plastic contamination present even in areas with low tourism activity, suggesting diffuse sources beyond local littering.
Plastic litter in sediments from the coasts of south Tuscany (Tyrrhenian Sea)
Plastic litter (macro, meso, and micro sizes) was found in sediments along a large stretch of the Tyrrhenian Sea coast of southern Tuscany, Italy, with microplastics dominating. The study provides baseline data for a region with significant coastal development and tourism.
Microplastic Contamination in Protected Areas of the Gulf of Venice
Plastic pollution was found in nearly all seven protected marine areas studied in the Gulf of Venice, with microplastics dominating. The findings suggest that official conservation status does not shield coastal sediments from plastic contamination.

Researchers surveyed littoral sediments of the Persian Gulf for microplastics, finding plastic particles across all sampling sites with a variety of polymer types. The study provides early baseline contamination data for a region with major petrochemical and industrial activity.
Assessment of microplastics distribution and stratification in the shallow marine sediments of Samos island, Eastern Mediterranean sea, Greece
Researchers surveyed microplastic distribution in shallow marine sediments around Samos Island, Greece, finding the highest concentrations on beaches and lower levels in deeper offshore sediments.
