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.

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.

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.

Breaking the paradigm: Marine sediments hold two-fold microplastics than sea surface waters and are dominated by fibers

Researchers found that Mediterranean marine sediments contain approximately twice the microplastic concentration of sea surface waters, with fibers dominating across all habitats, challenging the paradigm that surface waters are the primary marine microplastic reservoir.

Microplastic contamination in the Pletera beach

Researchers collected data on microplastic distribution — including microfragments and microfibers — across multiple stations along the Pletera beach in Spain. The dataset documents microplastic concentrations in sediment (items per kg) from two survey periods, providing a baseline for ongoing coastal pollution monitoring.

Novel methodology approach for assessing microplastic distribution in marine habitats along the Spanish Western Mediterranean coast

Researchers developed an innovative integrative methodology to assess spatiotemporal variation in microplastic abundance across sea surface and sediment habitats along the Spanish Western Mediterranean coast from 2017 to 2024, characterising distribution patterns at multiple spatial scales.

Abundance and distribution of microplastics on sandy beaches of the eastern Moroccan Mediterranean coast

Researchers surveyed 19 sandy beaches along the eastern Moroccan Mediterranean coast and found microplastic concentrations ranging from 40 to 230 particles per kilogram of sand. Fibers were the most common shape, making up about 75 percent of all particles found, with polyethylene, polystyrene, and polypropylene as the dominant polymer types. The findings indicate a moderate level of microplastic contamination along this stretch of coastline.

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.

Microplastics in sediments: a comparison within zones located worldwide with different impact

Researchers collected 25 sediment samples from six coastal areas worldwide spanning depths from 1 to 426 meters during 2022 and 2023 to compare microplastic abundance in zones with different levels of anthropogenic impact. They found a mean microplastic concentration of 308.81 items per kg dry weight across all sites, ranging from 20.79 items per kg in touristic Palma, Mallorca to 872.95 items per kg in the highly urbanized Ilha da Mare in Brazil, with fibers comprising approximately 95% of detected particles.

Effects of distance to the sea and geomorphological characteristics on the quantity and distribution of microplastics in beach sediments of Granada (Spain)

Researchers characterized microplastic pollution on three beaches along the Granada coast of Spain, examining how distance from the sea and geomorphological features influence microplastic quantity and polymer composition in beach sediments. The study establishes regional baseline contamination levels and identifies spatial distribution patterns relevant to national and EU marine pollution directives.

Assessment of microplastic abundance and impact on recreational beaches along the western Algerian coastline

Researchers assessed microplastic abundance on three recreational beaches along the western Algerian coastline. The study found an average of about 55 microplastic items per square meter, predominantly fragments, and used a pollution index to characterize contamination levels, contributing important baseline data for understanding plastic pollution along the understudied North African Mediterranean coast.
