ClearOccurrence and Spatial Distribution of Microplastics in River Shore Sediments of the Rhine-Main Area in Germany
Researchers surveyed river shore sediments and documented the occurrence and spatial distribution of microplastics, finding that sediment accumulation zones along riverbanks are hotspots for microplastic deposition.
Microplastic abundance in beach sediments of the Kiel Fjord
Researchers assessed microplastic abundance in beach sediments at three sites in Kiel Fjord, Germany, finding plastics at all locations including one near a sewage treatment plant. The study highlights how multiple sources — recreational use, wastewater discharge, and plastic litter — contribute to microplastic accumulation in coastal sediments.
River inflow of microplastics and their distribution in sea areas on the example of the southern Baltic Sea
Researchers tracked the flow of microplastics from rivers into adjacent sea areas in the Baltic region, quantifying concentrations at the river-sea interface. River inflow was confirmed as a major delivery pathway for marine microplastic contamination in enclosed coastal seas.
Occurrence, distribution and sources of microplastics in beach sediments of Miri coast, NW Borneo
Researchers characterized microplastic pollution in the surface sediments of 10 European rivers, detecting particles at all sites with concentrations ranging from 14 to 895 particles per kilogram of dry sediment. Urban rivers showed the highest contamination levels.
Plastic pollution on the Baltic beaches of Kaliningrad region, Russia
Researchers surveyed microplastic contamination on Baltic Sea beaches in Russia's Kaliningrad region between 2015 and 2016, finding 1.3 to 36.3 items per kg dry sediment with foamed plastic predominating, and detecting no clear difference in contamination levels between high- and low-traffic beach sites.
Study on the Mass Concentration Distributions of Marine Microplastics in Estuaries and Coastal Areas
Researchers characterized the mass concentration distribution of marine microplastics in estuarine and coastal environments, measuring spatial gradients between river mouths and open coastal waters and identifying estuaries as major transition zones for microplastic flux.
Micro- and Mesoplastic Monitoring on Beaches: Understanding Seasonal and Spatial Distribution Patterns
Researchers monitored microplastic abundance and composition across 11 Latvian Baltic Sea beaches over four seasons from autumn 2022 to summer 2023, finding that seasonal climate patterns and proximity to the Gulf of Riga influence both microplastic load and spatial distribution along the northeastern European coastline.
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.
Spatiotemporal Variability of Microplastics in the Eastern Baltic Sea
Researchers documented spatiotemporal variability of microplastics in the eastern Baltic Sea over five years, finding concentrations ranging from 0.01 to 2.45 particles per cubic meter with patterns linked to proximity to urban areas and riverine inputs.
Microplastic abundance in beach sediments of the Kiel Fjord, Western Baltic Sea
Microplastic abundance (0.2-5 mm) was assessed in drift line sediments from three Kiel Fjord sites differing in visitor use, proximity to a sewage plant, and nearby large-plastic litter. Results revealed that local sources including sewage infrastructure and beach visitor activity influenced microplastic concentrations at specific sites.
Spatio-temporal variability in the abundance and composition of beach litter and microplastics along the Baltic Sea coast of Schleswig-Holstein, Germany
Beach litter and microplastics (20-5000 microns) were co-assessed along the Baltic Sea coast of Schleswig-Holstein in spring and autumn 2018, finding no correlation between macro and microplastic abundances, with a median of 2 microplastic particles per 500 g dry sediment and six polymer types identified.
River inflow of microplastics and their distribution in sea areas on the example of the southern Baltic Sea
This study assessed the transport of microplastics from river inflow to distribution in adjacent sea areas, using the Baltic Sea as a case study. River discharge was found to be a major pathway delivering microplastics to coastal marine environments.
Why sampling season and location matter for monitoring micro and mesoplastics on the beach
Researchers analyzed microplastic pollution across 11 marine beaches in Latvia over four seasons from autumn 2022 to summer 2023, demonstrating how sampling season and location significantly influence measured pollution levels in the Baltic Sea region due to seasonal weather patterns and local hydrodynamics.
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.
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.
Microplastic pollution in the Weser estuary and the German North Sea
Microplastics were characterized in water and sediment samples from the Weser estuary and German North Sea coast, with concentrations decreasing offshore and fibers dominating in all matrices, consistent with urban and industrial river inputs as the primary source of coastal North Sea microplastic contamination.
The occurrence and sources of microplastics to Arctic and sub-Arctic beaches: human influence on local microplastic hotspots
Researchers characterized microplastic occurrence and sources at Arctic and sub-Arctic beaches, finding that proximity to human settlements creates local hotspots, while more remote beaches receive microplastics primarily through long-range oceanic transport.
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.

Researchers assessed the extent and variability of microplastic pollution across multiple beaches in the Bristol Channel, UK, finding that depositional environment characteristics significantly influenced the abundance and distribution of microplastic contamination in beach sand.
Occurrence and spatial distribution of microplastics in the surface waters of the Baltic Sea and the Gulf of Riga
