A large-scale investigation of microplastic contamination: Abundance and characteristics of microplastics in European beach sediment
This large-scale investigation characterized microplastic contamination across a wide geographic area, documenting abundance and polymer types and providing a baseline dataset for tracking pollution trends over time.
Dataset of quantification and classification of microplastics in Mexican sandy beaches
This dataset presents the first national survey of microplastic contamination on 35 Mexican beaches across five coastal regions. Microplastics were found at all beaches, with fragments and pellets being the most common types, providing baseline data for monitoring plastic pollution along Mexico's coasts.
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.
Microplastic debris in beaches of Tenerife (Canary Islands, Spain)
Researchers surveyed microplastic abundance and composition at six beaches on Tenerife in the Canary Islands, finding widespread contamination with pellets and fragments dominated by polyethylene and polypropylene, with higher concentrations on exposed north-coast beaches.
Microplastics at the strandlines of Slovenian beaches
Researchers collected sediment samples from nine locations along the Slovenian Adriatic coast and found microplastics at all sites, with 11.3% of isolated particles confirmed as synthetic polymers by ATR-FTIR, dominated by polyethylene and polypropylene fragments and fibers.
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.
Beneath the water column: Uncovering microplastic pollution in the sublittoral coastal sediments of the Canary Islands, Spain
This study examined microplastic prevalence and distribution in sublittoral coastal sediments around the Canary Islands, Spain, sampling 26 locations to characterize both synthetic and cellulosic particle contamination. The results establish a baseline for microplastic pollution in this Atlantic archipelago.
From macro to micro: dataset on plastic contamination along and across a sandy tide-less coast (the Curonian Spit, the Baltic Sea)
This dataset documents the distribution and abundance of plastic litter across size classes — from macroplastic to microplastic — on beaches of the Curonian Spit UNESCO Reserve in the Baltic Sea. The data provide a baseline for tracking plastic pollution in a sensitive protected coastal environment.
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.
Microplastics levels, size, morphology and composition in marine water, sediments and sand beaches. Case study of Tarragona coast (western Mediterranean)
Researchers measured microplastic levels, sizes, shapes, and polymer types in coastal water, sediment, and beach sand along the Tarragona coast of the western Mediterranean, finding widespread contamination associated with nearby industrial facilities and a major petrochemical complex.
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.
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.
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.
Microplásticos en tres playas del corredor turístico del norte, Piura, Perú
