The Assessment of the Bioaccumulation of Microplastics in Key Fish Species from the Bulgarian Aquatory of the Black Sea
Researchers found microplastics in the soft tissues of five commercially important Black Sea fish species collected off the Bulgarian coast, with polyethylene and polyethylene terephthalate as the dominant polymer types. Pellets were the most common particle shape, found across all specimens regardless of species. The results indicate significant microplastic contamination in a major regional seafood source, raising concerns about the potential for plastics to move up the food chain and reach people who consume these fish.
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.
The Global Spread of Microplastics: Contamination in Mussels, Clams, and Crustaceans from World Markets
Researchers used a standardized method to analyze microplastic contamination in commercially sold clams, mussels, and crustacean shellfish from markets in Belgium, Croatia, Serbia, and South Korea. Microplastics were found in about 44% of the 190 samples, with less than one particle per individual on average, and crustacean shellfish had the lowest contamination per gram of edible tissue. The type of shellfish was a stronger predictor of contamination levels than geographic origin, and the data did not support bioaccumulation with animal size.
An examination of the occurrence and potential risks of microplastics across various shellfish
Researchers compared microplastic contamination levels in commercial shellfish from northern (Qingdao) and southern (Xiamen) China, finding microplastics in 70-100% of samples. The study assessed potential human health risks from consuming contaminated shellfish, with microplastic abundances varying across species and geographic locations.
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.
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.
Microplastics contamination in bivalves from the Daya Bay: Species variability and spatio-temporal distribution and human health risks
Researchers assessed microplastic contamination in six species of bivalves from Daya Bay, China, finding microplastics present in 87 to 93% of individuals sampled. Sediment-dwelling bivalves had higher microplastic levels than water-dwelling species, and the types of microplastics found in the shellfish matched those in the surrounding seawater and sediment. A risk assessment based on polymer hazard levels indicated that microplastic contamination in these bivalves may pose health risks to humans who consume them as seafood.
Microplastic Contamination from Ready-to-Cook Clams: Implications for Food Safety and Human Exposure
Researchers characterized microplastic contamination in ready-to-cook frozen clams from commercial sources, assessing particle morphology, chemical identity, and polymer hazard index, and estimated average daily intake for consumers to evaluate food safety implications of microplastic contamination in bivalve seafood.
Multi-matrix approach to microplastic pollution in the bivalve Donax trunculus, sediment and water along the Mediterranean coasts
Researchers studied microplastic contamination across three connected elements along Italy's Mediterranean coast: wedge clams, sediment, and seawater. Both young and adult clams contained microplastics, with fibers being the most common type, confirming that these shellfish accumulate plastic particles from their environment. Since wedge clams are harvested for human consumption, the study highlights how microplastics in coastal waters enter the seafood supply.
Evaluation of human exposure to microplastics and nanoplastics related to the consumption of the striped venus clam Chamelea gallina caught in the Central Adriatic Sea (PLASTICVONG project)
Researchers quantified microplastic and nanoplastic contamination in striped venus clams from Italian coastal waters and estimated consumer exposure through shellfish consumption. Both microplastics and nanoplastics were found in clam tissues, with exposure levels dependent on harvesting location and consumption frequency.
Microplastics in commercial fish and their habitats in the important fishing ground of the Black Sea: Characteristic, concentration, and risk assessment
Researchers analyzed microplastic contamination in six commercial fish species from the Black Sea and found microplastics in all environmental areas studied, including surface water, the water column, sediments, and fish. Fibers were the most common type of microplastic found, and bottom-dwelling fish had higher contamination levels than fish living closer to the surface. Since these are commonly eaten fish species, the findings are relevant to human dietary exposure to microplastics.
