ClearMicroplastic Particles in Sandy Beaches of Thessaloniki Gulf, Greece
Microplastic particles — fragments and fibers — were detected in beach sediments at three sampling locations along Thessaloniki Gulf in Greece, with higher concentrations near populated areas. The findings contribute to the growing documentation of microplastic contamination on Mediterranean beaches.
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.
Quantification and characterization of microplastics in the Thermaic Gulf, in the North Aegean Sea
Researchers collected and analyzed microplastics from seawater, beach sediments, and seven commercial fish species in the Thermaic Gulf of the North Aegean Sea in Greece. They recorded over 28,000 microplastic particles across all environmental samples, classifying them by size, shape, color, and polymer type. The study adds to the growing evidence that the Mediterranean Sea is heavily affected by microplastic pollution across multiple environmental compartments.

Spatial and Seasonal Abundance of Microplastics in Sand and Aqueous Matrices from Coastal Areas of Northern Greece
Researchers collected and analyzed microplastics from wastewater effluents, beach sand, and seawater in Northern Greece over one year to capture seasonal variation. MP abundance varied seasonally, with higher concentrations in summer months likely linked to increased tourism and beach activity.
Microplastic pollution in the Greek seas
This research investigated the distribution patterns of floating microplastics (300 µm - 5 mm) in Greek seas, finding high variability in concentrations (0.012 to 1.62 items/m2) with maximum concentrations associated with surface slicks rather than predicted hotspot locations near pollution sources. The study also examined microplastic morphological characteristics, with fragments being the dominant form found across the sampled areas.
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.
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.
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.
Linking the Tourism Activity to the Occurrence and Distribution of Microplastics
Researchers assessed microplastic abundance, type, and spatial distribution in coastal water, sediments, and fish across three zones of Gili Trawangan, Indonesia, finding that tourism-related activities concentrated microplastics at recreational beaches with concentrations reaching 19.25 particles/L.
Plastic pellets, meso- and microplastics on the coastline of Northern Crete: Distribution and organic pollution
Researchers surveyed plastic pollution — including pellets, meso-, and microplastics — along the coastline of northern Crete, documenting their distribution patterns and identifying local hotspots tied to human activity and ocean current dynamics.
Plastic debris and microplastics along the beaches of the Strait of Hormuz, Persian Gulf
Researchers surveyed microplastic abundance along beaches of the Strait of Hormuz in the Persian Gulf, finding concentrations that reflected local anthropogenic activity levels — up to 1,258 particles per kg at the most industrialized site — with fibers dominating and polyethylene, nylon, and PET as the most common polymers.
Microplastics on beaches along the eastern Gulf of Thailand – A preliminary study
Researchers quantified microplastics at the high-tide line of 21 beaches along the eastern Gulf of Thailand, finding highly variable contamination levels ranging from 420 to over 200,000 particles per kilogram of sand.
Exploring the microplastic pollution: Unveiling origins and varieties in coastal sediments and waters of the Bushehr Province, Persian Gulf, Iran
Researchers conducted a comprehensive survey of microplastic pollution in coastal sediments and waters along the Persian Gulf in Iran. They found microplastics at all sampling sites, with the highest concentrations near petrochemical facilities and urban centers, and fibers being the most common type. The study establishes baseline pollution data for the region and links contamination levels to specific human activities.
Characteristics of microplastics on two beaches affected by different land uses in Salamina Island in Saronikos Gulf, east Mediterranean
Researchers compared microplastic pollution on two beaches of Salamina Island, Greece, and found differences tied to land use — one beach near industrial areas had more polyethylene fragments, while the other had more diverse plastic types. The study demonstrates how local human activities shape the types and amounts of microplastics found on nearby beaches.
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.
Changes 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.
Occurrence and abundance of macro, meso and microplastics along the coasts of the Persian Gulf (case study: Bushehr Province coast)
This survey of 17 coastal stations in Iran's Bushehr Province on the Persian Gulf documented widespread plastic pollution at macro, meso, and microplastic scales, with fibers making up the majority and fragments under 500 micrometers being most common. Polyethylene, polystyrene, PET, and nylon were the dominant polymer types identified by infrared analysis. The Persian Gulf is a semi-enclosed, heavily industrialized sea, and this data establishes baseline contamination levels needed to track how pollution changes over time.
