Evaluation of abundance of microplastics in the Bulgarian coastal waters
This study assessed microplastic pollution in Bulgarian Black Sea coastal waters across different site types — protected, aquaculture, and industrial zones — providing one of the first quantitative datasets for this undermonitored region. The presence of microplastics in all areas, including protected sites, indicates that contamination is pervasive and that Black Sea marine organisms face widespread exposure to particles that can also carry adsorbed chemical pollutants.
Transboundary Tides: Investigating Marine Plastic Pollution and Its Impact on the Black Sea Coastline
Researchers surveyed beaches in Romania along the Black Sea coast for plastic and microplastic litter, using harmonized EU monitoring methods including beach transect surveys and sediment sampling. Results revealed significant accumulation of plastic debris with transboundary origins confirmed by litter composition analysis, underscoring the need for coordinated regional action.
Comprehensive Review regarding the Profile of the Microplastic Pollution in the Coastal Area of the Black Sea
This literature review profiled microplastic pollution across the Black Sea, summarizing contamination levels in water, sediment, and seafood consumed by coastal populations. The Black Sea's unique hydrodynamics and heavy riverine inputs create hotspots for microplastic accumulation, with seafood contamination posing direct human exposure concerns.
Quantitative and qualitative evaluation of plastic particles in surface waters of the Western Black Sea
Researchers collected surface water samples from the Western Black Sea near the Danube Delta and Romanian shore, finding micro-, meso-, and macroplastic particles that may contribute significantly to Mediterranean marine pollution via the connecting waterway. Organic matter was digested and plastic particles were isolated and characterised to quantify and identify the polymer types present.
Sedimentary microplastic concentrations from the Romanian Danube River to the Black Sea
Researchers measured microplastic concentrations in sediments along the Danube River through the Danube Delta and into the Black Sea, finding that some isolated areas of the Delta still had relatively few plastic particles. The study helps clarify how microplastics move from major rivers into the ocean, an important step for estimating global ocean plastic loads.
Characterisation of floating microplastic in Romanian coastal waters, Western Black Sea
Researchers characterized floating microplastic distribution in Romanian coastal waters of the western Black Sea, analyzing 2,526 particles collected from five locations in March 2024. They found an average concentration of 3.07 particles per cubic meter, with fibers as the most common morphotype, and documented the polymer composition and color distribution across coastal sites.

Microplastics and floating litter pollution in Bulgarian Black Sea coastal waters
Researchers conducted a pilot study of floating marine litter and microplastics along the Bulgarian Black Sea coast, finding high quantities of floating litter (60.3-93.8 items per km) and microplastic concentrations of 0.114 to 1.91 x 10 items per km. Concentrations were on average lower than in other parts of the Black Sea, Baltic Sea, and Mediterranean Sea, though observed ranges were comparable.
Assesment of the Marine Litter on the Romanian Black Sea Beaches
Seasonal surveys of Romanian Black Sea beaches found cigarette butts and plastic fragments as the most common litter types, with plastic pollution varying by level of tourist activity. Beach surveys like this establish baseline data for tracking progress on reducing plastic pollution in coastal areas.
Microplastic Pollution Profile in the Black Sea Region
Researchers reviewed 100 peer-reviewed articles to create a comprehensive pollution profile of microplastics in the Black Sea region. They found that microplastics have been documented across multiple environmental compartments in the region, with plastic products from various industrial sectors contributing to contamination. The review provides an overview of the current state of knowledge on microplastic distribution and sources specific to this ecologically important semi-enclosed sea.
Indicators to assess temporal variability in marine connectivity processes: A semi-theoretical approach
Not relevant to microplastics — this is an oceanography study developing indicators to characterize temporal variability in marine connectivity for designing effective marine protected area networks in the Mediterranean.
Exploring the Microplastics Distribution in the Bottom Sediments of the Western Black Sea
Researchers surveyed the bottom sediments of the western Black Sea and found microplastic particles at every sampling site, with fibers the most common shape and polyethylene/polypropylene the most common polymer types. The widespread presence across the shelf zone, without a clear pattern tied to distance from shore, suggests diffuse anthropogenic inputs rather than a single point source — a finding that complicates clean-up and monitoring efforts for this semi-enclosed sea.
Research and Analysis of Pollution Indicators in Marine and Coastal Ecosystems along the Southern Black Sea Coast
Researchers conducted monthly in situ measurements and laboratory analyses at nine sites across Burgas Lake, the Karaagach River mouth, and Burgas Bay along the Southern Black Sea coast during 2022-2023, performing the first quantitative microplastic analysis in the region alongside toxic metal measurements to assess ecosystem pollution status.
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.
Identification and Quantitative Pollutant analysis: A novel approach for environmental assessment in the Romanian Black Sea Coast
This paper examined multiple pollution factors affecting the Black Sea Romanian coastal zone, including microplastics, heavy metals, PAHs, and emerging substances, with attention to impacts from the ongoing Russian-Ukrainian conflict and military activities. It proposed an integrated multi-pollutant assessment framework for characterizing coastal marine ecosystem health.
High microplastic pollution in marine sediments associated with urbanised areas along the SW Bulgarian Black Sea coast
Researchers measured microplastic concentrations in beach and seabed sediments along the southwestern Bulgarian Black Sea coast. Urbanized coastal areas had significantly higher microplastic levels than non-urbanized areas, with seabed samples averaging over 800 particles per kilogram of dry sediment. The study identified sewage discharges, urban waste, fisheries, and marine litter accumulation as likely sources of the contamination.
Microplastic Contamination of the Seawater in the Hamsilos Bay of the Southern Black Sea
Researchers monitored microplastic contamination in the water column of Hamsilos Bay, a protected natural area on the Black Sea coast of Turkey, over 12 months. They found microplastics at all sampling stations, with fibers being the dominant type and polyethylene terephthalate the most common polymer identified. The study demonstrates that even protected coastal areas are not immune to microplastic pollution and provides important baseline data for this ecologically sensitive region.
