Plastic contamination of sandy beaches along the southern Baltic – a one season field survey results

Researchers surveyed microplastic and macroplastic contamination along the Polish Baltic Sea coast, finding microplastic concentrations of 118–1,382 pieces/kg in beach sand and 0.61–2.76 pieces/dm3 in coastal waters, with sub-1 mm blue fibers dominating across all sites and suggesting a common fibrous source throughout the Polish coastal zone.

Microplastics on sandy beaches of the southern Baltic Sea

Microplastics were detected on all 12 beaches along the Polish Baltic coast at concentrations of 76 to 295 items per kilogram of sediment, with fibers and fragments dominant and no strong relationship to sediment grain size. Urban beaches had the highest concentrations, though beach hydrodynamics also played a significant role in structuring local microplastic distribution.

From macro to micro, from patchy to uniform: Analyzing plastic contamination along and across a sandy tide-less coast

A survey of a protected coastline in Lithuania found that while macrolitter is patchy and variable, microplastics (0.5–5 mm) are far more uniform, averaging over 3,000 particles per square meter of beach sand. Even in protected natural areas, microplastic contamination is pervasive.

Microplastics in seawater and fish acquired from the corresponding fishing zones of the Baltic Sea

Microplastics were detected in 100% of seawater and 61% of fish samples collected from corresponding fishing zones of the Baltic Sea, with mean abundances of 19,984 items/m³ in seawater and 3.3 items per fish. The co-sampling design linking fish MP loads to their water column environment provided direct evidence of aquatic exposure driving tissue contamination.

Microplastics distribution in bottom sediments of the Baltic Sea Proper

Researchers found microplastics in Baltic Sea Proper bottom sediments ranging from 103 to 10,179 items per kg dry weight across 53 samples, with abundance increasing significantly with water depth. Fibrous particles dominated at 74.5% and appeared to behave as a distinct type of 'synthetic sediment,' following erosion-transition-accumulation patterns similar to natural sediment.

Pollution of Beach Sand from Selected Recreational Reservoirs by Microplastics

Researchers analyzed beach sand samples from three recreational reservoirs in southern Poland (Silesian Voivodship) to assess microplastic pollution levels in freshwater beach environments. The study found microplastics present in beach sand across all sampled sites, contributing to evidence that sediments and beach sands serve as long-term microplastic sinks in aquatic environments.

Micro- and Mesoplastic Monitoring on Beaches: Understanding Seasonal and Spatial Distribution Patterns

Researchers monitored microplastic abundance and composition across 11 Latvian Baltic Sea beaches over four seasons from autumn 2022 to summer 2023, finding that seasonal climate patterns and proximity to the Gulf of Riga influence both microplastic load and spatial distribution along the northeastern European coastline.

Sources and fate of microplastics in marine and beach sediments of the Southern Baltic Sea—a preliminary study

Researchers investigated microplastic sources and distribution in marine and beach sediments of the southern Baltic Sea — one of the most polluted regional seas — using density extraction and FT-IR identification. The study found widespread contamination with significant variability tied to local sources and hydrodynamic transport patterns.

Mikroplastik Pada Sedimen di Zona Pemukiman, Zona Perlindungan Bahari dan Zona Pemanfaatan Darat Kepulauan Karimunjawa, Jepara

This Indonesian study investigated microplastic types and abundances in sediments across different zones of the Karimunjawa National Park, comparing residential, marine protected, and buffer zones. The results show that even protected marine areas in Indonesia are not immune to microplastic contamination.

Spatial distribution of macro- and micro-litter items along rocky and sandy beaches of a Marine Protected Area in the western Mediterranean Sea

Macro- and micro-litter were mapped across rocky and sandy beaches within a marine protected area in the Balearic Islands, finding a mean macrolitter concentration of about 1.9 items per square meter and widespread microplastic presence in sandy sediments. Plastic fragments and films were the dominant litter categories, highlighting recreational pressure even in protected coastal areas.
