ClearOccurrence of microplastics in Mytilus edulis and Arenicola marina collected along the French-Belgian-Dutch coast
Researchers measured microplastics in blue mussels and lugworms collected from beaches along the French, Belgian, and Dutch coasts, finding microplastics in both species at levels reflecting environmental concentrations. The study bridged the gap between high-concentration lab experiments and field reality by documenting actual microplastic contamination in these commonly consumed and studied marine species.

Researchers surveyed sediments from Norderney in the North Sea and found widespread microplastic contamination, documenting spatial distribution patterns and particle characteristics across this tidally influenced coastal environment.
Prey choice and ingestion of microplastics by common shelducks and common eiders in the Wadden Sea World Heritage Site
Researchers found microplastic contamination in over 92% of stomach samples and 74–86% of fecal samples from common eiders and common shelducks in the Wadden Sea, with plastic filaments under 5mm dominating, suggesting widespread and near-universal ingestion by these coastal seabirds.
Screening for microplastics in sediment, water, marine invertebrates and fish: Method development and microplastic accumulation
Researchers developed improved methods for extracting microplastics from biological samples and sediments, using enzymatic digestion that achieved 97% particle recovery without damaging the plastics. When applied to field samples from the North Sea and Swedish coast, they found microplastics in 8 of 9 invertebrate species tested and in 68% of brown trout. Mussel tissue contained roughly a thousand times more microplastic particles per kilogram than surrounding sediment or water.
Occurrence and distribution of microplastics in marine sediments along the Belgian coast
Researchers surveyed marine sediments along the Belgian coast and found microplastics distributed across all sampled sites, documenting their occurrence and characteristics in this heavily trafficked North Sea coastal environment.
Microplastic distribution and composition in mudflat sediments and varnish clams (Nuttallia obscurata) at two estuaries of British Columbia, Canada: An assessment of potential anthropogenic sources
This study characterized the distribution, composition, and abundance of microplastics in mudflat sediments and in the tissues of varnish clams, a commercially harvested bivalve. High microplastic loads in both sediment and clam tissue raised concerns for seafood consumers and intertidal ecosystem health.
Abundance, composition, and distribution of microplastics in intertidal sediment and soft tissues of four species of Bivalvia from Southeast Brazilian urban beaches
Researchers found 100% microplastic contamination in intertidal sediments and four bivalve species from urbanized Brazilian beaches, identifying polypropylene, polyethylene, and PET polymers in organisms commonly consumed by humans.
Microplastics in marine invertebrates from the Red Sea Coast of Egypt: Abundance, composition, and risks
This is the first study to document microplastics in marine invertebrates along Egypt's Red Sea coast, examining 11 species of clams, snails, sea urchins, and sea cucumbers. Every animal sampled contained microplastics, with filter-feeding bivalves showing the highest concentrations per gram of tissue. The plastics identified were linked to tourism-related sources, highlighting how coastal recreation contributes to wildlife contamination.
Microplastic abundance in beach sediments of the Kiel Fjord
Researchers assessed microplastic abundance in beach sediments at three sites in Kiel Fjord, Germany, finding plastics at all locations including one near a sewage treatment plant. The study highlights how multiple sources — recreational use, wastewater discharge, and plastic litter — contribute to microplastic accumulation in coastal sediments.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Distribution and Characteristics of Microplastics in Barnacles and Wild Bivalves on the Coast of the Yellow Sea, China
Researchers surveyed microplastic contamination in wild barnacles and bivalves along the Yellow Sea coast of China. They found microplastics in all sampled organisms, with fibers being the dominant type, and observed spatial variation in contamination levels across different coastal sites. The study provides baseline data on microplastic pollution in wild shellfish populations that are smaller and potentially more vulnerable than farmed species.
Nanoplastics and ultrafine microplastic in the Dutch Wadden Sea – The hidden plastics debris?
Researchers applied a novel analytical method to detect nanoplastics and ultrafine microplastics smaller than 10 micrometers in Dutch Wadden Sea sediments, revealing a previously hidden fraction of plastic debris that conventional methods miss.
Microlitter in Fish and Benthic Invertebrates of the NE Baltic Sea: Abundance, Composition and Bioindicators
Researchers characterized microlitter abundance, composition, and bioindicator potential in fish and benthic invertebrates from multiple sites in the NE Baltic Sea, including the Gulf of Finland, Gulf of Riga, and western Estonia, following HELCOM methodology. Examining 11 fish species and 6 benthic invertebrate species collected during 2019-2020, the study evaluated resident marine fauna as monitors of microplastic contamination.
An enhanced risk assessment framework for microplastics occurring in the Westerscheldt estuary
Researchers developed an enhanced risk assessment framework for microplastics in the Westerscheldt estuary by surveying contamination levels in river sediments and water. They found significant microplastic pollution with abundances varying by location, and identified wastewater discharge and urban runoff as key sources. The study provides a structured approach for evaluating ecological risks from microplastic contamination in estuarine environments.
Microplastic prevalence, diversity and characteristics in commercially important edible bivalves and gastropods in relation to environmental matrices
Researchers assessed microplastic abundance and characteristics in the tissues of commercially important bivalves and gastropods from the southwest coast of India, finding MPs across all five species examined and raising concerns about seafood safety.
Microplastics contamination in molluscs from the northern part of the Persian Gulf
Researchers analyzed microplastic contamination in five species of mollusks from the northern Persian Gulf, including both gastropods and bivalves with different feeding strategies. They found microplastics in all species, with concentrations ranging from 0.2 to 21 particles per gram of soft tissue, and fibers were the most common type. The study indicates that microplastic contamination is widespread in Persian Gulf seafood and that filter-feeding organisms tend to accumulate more particles.
Microplastic pollution in the Weser estuary and the German North Sea
Microplastics were characterized in water and sediment samples from the Weser estuary and German North Sea coast, with concentrations decreasing offshore and fibers dominating in all matrices, consistent with urban and industrial river inputs as the primary source of coastal North Sea microplastic contamination.
