ClearChanges in (micro and macro) plastic pollution in the sediment of three sandy beaches in the Eastern Mediterranean Sea, in relation to seasonality, beach use and granulometry
Researchers measured plastic and microplastic pollution in sediment from three Mediterranean beaches across seasons, finding that smaller microplastics accumulate at the backshore while larger items concentrate near the waterline. Seasonal patterns and beach use intensity affected plastic abundance, with implications for beach management and cleanup strategies.
Presence, Spatial Distribution, and Characteristics of Microplastics in Beach Sediments Along the Northwestern Moroccan Mediterranean Coast
Researchers surveyed fourteen beaches along the northwestern Moroccan Mediterranean coast and found microplastics in every sediment sample, averaging about 59 particles per kilogram of dry sand. Fibers were the dominant shape at nearly 78%, with tourism, fishing, and wastewater discharges identified as the most likely pollution sources. The findings indicate moderate but widespread microplastic contamination along this coastline.
Relationships between sediment size distribution and microplastic abundance and characteristics along the strandline of a sandy embayment (Whitsand, Southwest England)
Researchers analyzed the relationship between sediment characteristics and microplastic distribution along a beach in southwest England. They found that microplastic abundance and type varied significantly across the strandline, with larger microplastics being more prevalent in coarser sediments. The study provides evidence that local sediment dynamics play an important role in determining where microplastics accumulate on sandy beaches.
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.
Sediment grain size determines microplastic exposure landscapes for sandy beach macroinfauna
Researchers studied microplastic distribution across sandy beach zones to understand exposure landscapes for intertidal organisms. They found that sediment grain size, rather than beach zonation, was the primary factor determining microplastic abundance, providing important guidance for designing sampling surveys and assessing ecological risk from microplastic pollution on beaches.

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.
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.
Microplastic levels on sandy beaches: Are tourism and coastal recreational activities effects really important?
Researchers assessed microplastic levels at six sites across three Argentine sandy beaches with varying tourism intensity, finding concentrations averaged 1,133 items/kg in sand and 12.7 items/m3 in seawater, dominated by PE films and PET/cotton fibers. Contrary to expectations, the highest microplastic concentrations and smallest particles were found at a low-activity 'pristine' site, suggesting river proximity and coastal drift rather than tourism are the dominant local pollution drivers.
Factors driving the abundance and distribution of microplastics on sandy beaches in a Southwest Atlantic seaside resort
Researchers investigated factors driving microplastic abundance on sandy beaches along the Southwest Atlantic coast, finding that both natural forces like wave energy and anthropogenic inputs influenced the distribution of fiber and fragment microplastics in surface sediments.
Morphodepositional Insights into Microplastics and Microfibers in Beach Sediments of the Vesuvian Coast, Southern Italy
Researchers characterized microplastics and microfibers in beach sediments of the Vesuvian coast in southern Italy, examining how particle shape, surface properties, and coastal morphology influence their spatial distribution. Fibers dominated the samples, and sediment trap zones associated with beach morphology accumulated higher particle densities, demonstrating the role of local hydrodynamics in microplastic deposition patterns.
Macro-, meso- and microplastic abundance in sandy beaches and factors influencing their distribution in an SW Atlantic resort
Researchers surveyed macro-, meso-, and microplastic abundance in marine sediments of tourist beaches in the Southwest Atlantic (Argentina), using generalized linear models to identify how beach morphology, grain size, and human activity influence plastic distribution.
Factors Influencing the Three-dimensional Distribution of Microplastics on Sandy Beaches: A Case Study from the Turkish Coast of the Black Sea
A study of nine Black Sea beaches in Turkey found that microplastic abundance varied significantly with beach width, sand grain size, organic content, and tourism pressure, revealing that local physical and human factors shape how microplastics accumulate across the three-dimensional sediment profile. These findings help explain why microplastic hotspots form on particular beaches and can guide targeted cleanup and monitoring efforts.
The relation of sediment texture to macro- and microplastic abundance in intertidal zone
Researchers analyzed the relationship between sediment grain size and microplastic accumulation in an intertidal zone, finding that finer-grained sediments tend to accumulate more plastic particles. Understanding this relationship helps identify which coastal areas are at greatest risk from microplastic contamination.
Microplastic accumulation dynamics in two Mediterranean beaches with contrasting inputs
Researchers monitored microplastic accumulation dynamics on two Mediterranean beaches with contrasting human pressures over multiple seasons, finding that beaches near urban areas accumulated MPs faster and showed greater concentration variability. Short-term accumulation events tied to storms and wind patterns were identified as key drivers of MP deposition.
