Microplastic beaching dependence on sediment grain size

Researchers sampled microplastics across a Mediterranean protected beach and found that accumulation is strongly influenced by sediment grain size — fine-grained sands trap more surface microplastics due to lower infiltration capacity — while fiber shape promotes entanglement in sediment pores and proximity to tourism and port activities drives spatial pollution hotspots.

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.

Short-term tourism alters abundance, size, and composition of microplastics on sandy beaches

Researchers sampled microplastics on nine sandy beaches along the Turkish Black Sea coast before and after the tourism season and found that tourist activity significantly increased microplastic abundance, altered size distributions, and changed polymer composition. The results provide direct field evidence that recreational beach use is a local source of microplastic pollution.

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.

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. The study suggests that beaches act as accumulation zones for microplastic pollution carried from land.

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.

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.

First full investigation of levels of microplastics on sandy beaches in Malta

This study conducted the first comprehensive survey of microplastic levels on sandy beaches in Malta, finding microplastics at all five sampled beaches including in protected coastal areas. The results establish baseline contamination levels for the central Mediterranean and document seasonal and spatial variability.

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 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.

Assessment of beach litter pollution in Egypt, Tunisia, and Morocco: a study of macro and meso-litter on Mediterranean beaches

Researchers surveyed 37 Mediterranean beaches in Egypt, Morocco, and Tunisia for plastic litter, finding that urban and tourist beaches were most heavily polluted, with macro-litter averaging over 5,000 pieces per 100 meters. The study also developed a faster, cost-effective monitoring method and concluded that beach cleaning alone cannot solve the problem — better waste management and public awareness are essential.

An evaluation of surface micro- and mesoplastic pollution in pelagic ecosystems of the Western Mediterranean Sea

Researchers found that micro- and mesoplastic debris were widely and uniformly distributed across the Western Mediterranean Sea, with average surface concentrations of approximately 130,000 microplastic particles per km2 and 5,700 mesoplastic particles per km2. Fragment morphology and polymer composition analysis indicated a predominantly land-based origin for the debris.

Spatio-temporal variation and ecological risk assessment of microplastics along the touristic beaches of a mediterranean coast transect (Valencia province, East Spain)

Researchers sampled microplastics from seven tourist beaches along Spain's Valencia coast in both winter and summer and found contamination levels nearly five times higher during the summer tourism season. Fibers were the most common type of microplastic, and polyethylene and halogenated polystyrene from food packaging were the dominant polymers identified. The study raises questions about whether current beach cleaning practices are sufficient to address microplastic pollution.

Spatiotemporal variations in rural and urban beach microplastics accumulation in sediment along Sarangani Bay Protected Seascape, Mindanao, the Philippines

Researchers measured microplastic contamination in beach sand at urban and rural sites along a protected seascape in the Philippines across wet and dry seasons. They found significantly higher microplastic levels during the wet season, particularly at urban beaches, likely because rainfall washes more plastic debris from land into waterways. The most common plastics identified were polyester and polyethylene, suggesting sources from textiles and common consumer packaging.
