Researchers assessed microplastic contamination in five commercially important fish species and Mediterranean mussels from the southern Marmara Sea in Turkey. They found microplastics in all species examined, with varying levels of contamination across different collection sites, and calculated hazard indices to estimate potential risks. The study provides evidence that seafood consumers in the region may face meaningful dietary exposure to microplastics.
Study on microplastic particles ingestion and the occurrence of related chemical additives in commercial fish species across different habitats of North Aegean Sea
This study examines microplastic ingestion in commercial fish species from the North Aegean Sea, along with chemical additives associated with the plastic particles. Different fish species from various habitats showed varying levels of contamination, suggesting that where and how fish feed affects their microplastic exposure. These findings are relevant to seafood safety since these are species commonly consumed by people.
Heavy metals and microplastics in the stomach contents of two fish species: Trachurus trachurus and Zeus faber along the North and Central Atlantic Coast of Morocco
Scientists examined the stomachs of two popular commercial fish species along the Moroccan Atlantic coast and found microplastics in 46% of the fish, mostly in the form of fibers made from polyamide, polystyrene, and acrylic. Heavy metals like mercury, cadmium, and zinc were also detected in 97% of samples, though levels stayed below regulatory limits. While the contamination risk from microplastics was generally low, the study flagged potential health concerns for children who frequently eat these fish.
Mercury Biogeochemistry and Biomagnification in the Mediterranean Sea: Current Knowledge and Future Prospects in the Context of Climate Change
This review examines mercury contamination in the Mediterranean Sea, where fish contain much higher mercury levels than Atlantic species, mainly due to environmental conditions that promote conversion of mercury into its most toxic form. Climate change is expected to worsen the problem by altering the marine food web in ways that increase mercury accumulation in predatory fish like tuna. While focused on mercury, the findings are relevant to microplastics research because microplastics can absorb and transport mercury and other heavy metals through aquatic food chains.
Formulation of a Target Plastic Model to estimate critical plastic burdens of toxicants.
This study created a "Target Plastic Model" to estimate the concentration of toxic chemicals in common plastics at which they would harm aquatic organisms, adapting an established chemical toxicity framework to plastic polymers. The model accurately predicted lethal concentrations for fish exposed to a range of chemicals, offering a new tool for assessing the risks posed by plastic-adsorbed pollutants and improving the design of passive sampling devices used in environmental monitoring.
The influence of ecological factors in the modulation of pollution biomarkers of two small pelagic marine fish
Researchers examined how ecological factors such as body condition, sex, and season modulate pollution biomarker responses in two small pelagic fish species, finding that biological variability must be accounted for when using hepatic biomarkers to assess marine contamination levels.
Abundance and ecological risk of microplastics in commercial fish species from northeastern Mediterranean Sea
Researchers examined nine commercially important fish species from the northeastern Mediterranean Sea and found microplastics in both their digestive tracts and gills. The most common particles were small polyethylene and polypropylene fibers, and bottom-dwelling fish species had higher contamination levels. While the ecological risk was rated low to medium, the presence of microplastics in widely consumed fish species highlights a potential pathway for human exposure through seafood.
Quantification and characterization of microplastics in the Thermaic Gulf, in the North Aegean Sea
Researchers collected and analyzed microplastics from seawater, beach sediments, and seven commercial fish species in the Thermaic Gulf of the North Aegean Sea in Greece. They recorded over 28,000 microplastic particles across all environmental samples, classifying them by size, shape, color, and polymer type. The study adds to the growing evidence that the Mediterranean Sea is heavily affected by microplastic pollution across multiple environmental compartments.
Exploring the Impact of Contaminants of Emerging Concern on Fish and Invertebrates Physiology in the Mediterranean Sea
This study examines how emerging pollutants including pharmaceuticals, heavy metals, pesticides, and microplastics affect marine organisms in the Mediterranean Sea. Researchers used catsharks and mussels as indicator species to measure contamination levels and biological effects. The findings are relevant to human health because contaminated seafood from the Mediterranean is widely consumed across Europe.
Ingestion and accumulation of microplastics in small marine fish and potential human exposure: case study of Binh Dinh, Vietnam
