MonitoringplasticandHgpollutionimpactsontwo commercial species from the North Evoikos Gulf
AI summary Read the abstract
Researchers sampled 230 bogue fish and 203 Norway lobster from the North Evoikos Gulf and detected microplastics in 56% of fish and 79% of lobster, with lobster carrying an average of 3.72 MPs per individual. Mercury concentrations were also measured, and the study linked both contamination types to anthropogenic pressures in this semi-enclosed sea.
This study examines the presence of microplastics (MPs) and mercury (Hg) concentrations in 230 Boop boops L., and 203 Nephrops norvegicus L., sampled from the North Evoikos during the years 2021, 2022 and 2024. Microplastics were detected in 56.1% ofB. boops, with a mean abundance of 1.74 MPs/individual, and in 79.3% of N. norvegicus, with a mean of 3.72 MPs/ individual. Polymer composition analysis revealed species-specific differences in the dominant MP types. Mercury concentrations remained within the permissible limits established by European regulatory standards, with mean levels of 0.32 mg/kg w.w. in N. norvegicus and 0.05 mg/kg w.w. in B. boops indicating no immediate risk to human health (THQ <1).

Microplastics in marine biota of North Aegean Sea: Summarizing and comparing preliminary findings
AI summary Read the abstract
Researchers examined microplastics ingested by three commercially harvested marine species — bogue fish, Mediterranean mussels, and blue crabs — in the North Aegean Sea, finding between 1 and 3 microplastic items per individual on average. Fragment-shaped particles smaller than 200 micrometers were most common, with polyethylene among the dominant polymer types, highlighting the contamination of seafood that humans consume.
Assessment of microplastic pollution in eleven commercial fish species in the Gulf of İzmir (Aegean Sea, eastern Mediterranean)
AI summary Read the abstract
Researchers examined 152 fish from 11 commercially important species in the Gulf of Izmir, Turkey, and found microplastics in 42% of them. Polyethylene fragments and fibers were the most common types found in fish digestive tracts, with surface-dwelling fish species showing higher contamination than bottom-dwelling ones. Since these are species commonly sold and eaten by people in the region, the study highlights a direct pathway for microplastic exposure through seafood consumption.
Assessing the relationship between the abundance of microplastics in sediments, surface waters, and fish in the Iran southern shores
AI summary Read the abstract
Researchers found microplastic contamination across sediments, surface waters, and four fish species along Iran's Persian Gulf coast, with concentrations of 190 items/kg in sediments and 9.28 items/km in surface waters, though no correlation was observed between MP abundance across the different environmental compartments.
Microplastics and Mercury Detection on Anchovy from Alor and Balikpapan Harbors, Indonesia
AI summary Read the abstract
Microplastics and mercury were detected together in anchovies from two Indonesian harbors, with both contaminants present in the digestive tracts. The co-occurrence of microplastics and a neurotoxic heavy metal in a widely consumed fish species raises compounded concerns about food safety.
Abundance and characteristics of microplastic in some commercial species from the Persian Gulf, Iran
AI summary Read the abstract
Scientists examined microplastic contamination in the digestive tracts of five commercially important fish and shellfish species from the Persian Gulf, finding plastic particles in nearly 73 percent of all individuals sampled. Microfibers were the most common type, making up about 58 percent of particles found, and polymer analysis identified polypropylene and polyethylene as the dominant plastics. The study highlights that seafood from the Persian Gulf region is widely contaminated with microplastics, raising concerns about potential exposure for human consumers.
