ClearMicroplastic occurrence in coastal waters and aquatic faunas of the Western Black Sea
Researchers assessed microplastic occurrence in coastal waters and aquatic fauna of the Western Black Sea region receiving Danube River inputs, characterizing MP distributions in a coastal ecosystem under pressure from tourism, fishing, regional conflicts, and inadequate waste disposal across the Danube basin.
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.

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.
An analysis of the current and forecasted ecological risk related to the presence of microplastics on the Romanian Black Sea coast
Researchers analyzed microplastics along 82 km of Romania's Black Sea coastline, finding densities between 122 and 536 particles per kilogram of sediment, with polyethylene as the dominant polymer. Forecasting models predict a sharp rise in ecological risk if plastic waste reduction and management practices are not urgently improved.
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.
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.
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.
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.
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.
Hydrodynamic Observations on Microplastic Abundances and Morphologies in the Danube Delta, Romania
This study measured microplastic abundance and morphology in fluvial and lake environments of the Danube Delta in Romania, finding microplastics distributed throughout the system. The findings show that the Danube Delta — an important biodiversity hotspot — receives significant microplastic inputs from the river.
Current status and comparative risk assessment of microplastic pollution in surface water and sediment from the Black Sea coastline using geospatial analysis
Researchers conducted the first comprehensive microplastic survey of Turkey's Black Sea coast, documenting a roughly 78% annual increase in surface water particle concentrations and a threefold rise at some sediment stations, with fibers and high-risk polymers like PET and PVC dominating both matrices and most sites rated high ecological risk.
Quantitative and qualitative analysis of microplastic pollution in a large European river
Researchers sampled the Budapest reach of the Danube River at multiple water column depths using a Multilevel Manta net, finding an average microplastic concentration of 0.311 mg/m³ (142 particles/m³) dominated by polystyrene, polyethylene, and polypropylene fragments, and estimating substantial microplastic mass flux that underscores the Danube's role as a major transport pathway for plastic pollution.
Microplastic pollution in stream sediments discharging from Türkiye's eastern Black sea basin
Researchers characterized microplastic pollution in stream sediments from rivers discharging into the southeastern Black Sea from Turkey. The study found microplastics across 59 sampling sites, with varying composition and abundance, confirming that rivers serve as a principal transport route for terrestrial microplastics into this semi-enclosed sea.
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.
Microplastics in the Black Sea sediments
Microplastics in Black Sea sediments were characterized by occurrence, morphology, and polymer type for the first time, using samples collected across a depth range of 22 to 2131 meters. The study tested a non-invasive filtration method and found microplastics across the sampled depth range, demonstrating vertical distribution of plastic pollution in the Black Sea.
