ClearProtracted dynamicity of microplastics in the coastal sediment of the Southeast Black Sea
Comparing sediment samples from the Southeast Black Sea coast collected a decade apart in 2012 and 2022, this study found that microplastic abundances had increased substantially and that fibers and fragments dominated, with the majority of detected polymers linked to regional fishing and tourism activities.
Microplastics in marine ecosystems: exposure, ingestion, and accumulation dynamics in seahorses
This Portuguese-language thesis investigated microplastic exposure, ingestion, and accumulation dynamics in seahorses from coastal marine environments. The study characterized microplastic types found in seahorse gastrointestinal tracts and assessed how seahorse feeding ecology and habitat use influence their microplastic accumulation.
First evidence of ingestion and retention of microplastics in seahorses (Hippocampus reidi) using copepods (Acartia tonsa) as transfer vectors
Researchers provided the first evidence that seahorse larvae (Hippocampus reidi) ingest and retain microplastics transferred through copepod prey, demonstrating trophic transfer of microplastics in early developmental stages of a vulnerable marine fish species.
Characteristics and temporal trends of microplastics in the coastal area in the Southern Black Sea over the past decade
Researchers investigated microplastic abundance, polymer types, and size distributions in seawater at three distances from the southeastern Black Sea coast over a decade (2009-2020). Polyethylene and polyethylene terephthalate dominated at 44.9% and 25.3% respectively, with fragment shapes most common, and no significant spatiotemporal changes in abundance were detected.
Monthly microplastics change in European anchovy's (Engraulis encrasicolus) gastrointestinal tract in the Black Sea
Researchers tracked monthly microplastic contamination in European anchovy from the Black Sea over a full year, finding seasonal variation in plastic ingestion that correlated with changes in feeding behavior and oceanographic conditions.
Preliminary Study on Microplastic Contamination in Black Sea Cetaceans: Gastrointestinal Analysis of Phocoena phocoena relicta and Tursiops truncatus ponticus
Researchers conducted a preliminary study of microplastic contamination in the gastrointestinal tracts of Black Sea harbor porpoises and bottlenose dolphins, documenting microplastic presence and characterizing particle types and polymer compositions.
Hallmarking microplastics of sediments and Chamelea gallina inhabiting Southwestern Black Sea: A hypothetical look at consumption risks
Researchers investigated microplastic contamination in sediments and the bivalve Chamelea gallina along the Southwestern Black Sea coast, finding 28-684 particles per kilogram in sediments and up to 2.17 particles per individual clam, with seven polymer types identified.
Plastic ingestion by pelagic and demersal fish from the North Sea and Baltic Sea
Researchers examined gastrointestinal tracts of 290 North and Baltic Sea fish and detected plastic in 5.5% of individuals, with pelagic species like herring and mackerel ingesting plastic at three times the rate of bottom-dwelling cod and flounder, and polyethylene making up nearly 40% of identified polymer types.
Investigation of Microplastic Accumulation in Horse Mackerel (Trachurus mediterraneus) Caught in the Black Sea
Horse mackerel (Trachurus mediterraneus) caught from Turkish coastal waters were found to contain microplastics in their gastrointestinal tracts, with fibers and fragments the most common types. The study contributes to baseline data on microplastic contamination in commercially important Mediterranean fish species.
Microplastics assessment in Arabian Sea fishes: accumulation, characterization, and method development
Researchers assessed microplastic accumulation in Arabian Sea fish species, developing optimized digestion protocols and characterizing polymer types to trace contamination sources, finding widespread microplastic ingestion across multiple commercially important fish species.
Microplastic ingestion and egestion by copepods in the Black Sea
Researchers assessed microplastic ingestion and excretion by copepods in the Black Sea for the first time, alongside measuring plastic pollution in the water column. They found microplastics at all sampling stations, with the highest concentrations near river mouths, and confirmed that copepods actively ingest and excrete these particles. The findings suggest that microplastic contamination is widespread in the Black Sea and is entering the base of the marine food web.
Occurrence of microplastics in the gastrointestinal tracts of four most consumed fish species in Giresun, the Southeastern Black Sea
Researchers examined four commonly eaten fish species from the Black Sea coast of Turkey and found microplastics in the digestive tracts of all four species. Bottom-dwelling fish had higher microplastic concentrations than surface-dwelling species, likely because microplastics settle and accumulate in sediments. Since these are popular commercial fish species, the findings underscore a direct route of microplastic exposure for seafood consumers in the region.
Microplastic contamination and characteristics spatially vary in the southern Black Sea beach sediment and sea surface water
Microplastic abundance and characteristics were assessed along the southern Black Sea coastline, finding that over 70% of particles were smaller than 2.5 mm, with average concentrations of 64 particles/kg in beach sediment and 18.68 particles/m3 in seawater, and the Marmara region showing highest pollution.
Seasonal monitoring of microplastic pollution in the Southeast Black Sea: An example of red mullet (Mullus barbatus) gastrointestinal tracts
Researchers found seasonal variation in microplastic occurrence in the gastrointestinal tracts of red mullet (Mullus barbatus) from the Southeast Black Sea, with the highest counts detected in winter and autumn, and fibers as the predominant shape across all seasons.
Plastic Occurrence in Commercial Fish Species of the Black Sea
Researchers examined plastic ingestion in seven commercial fish species from the Black Sea and found plastics in the gastrointestinal tracts of 29% of all individuals tested. Fibres were the most common type of plastic found, accounting for nearly 69% of all particles, with 93% being microplastics smaller than 5 mm. The study identified polypropylene, polyester, and acrylic as the most prevalent polymer types, indicating widespread microplastic contamination in Black Sea commercial fisheries.
