Occurrence of Microplastics in the Gastrointestinal Tracts (GITs) of the Common Dolphinfish, Coryphaena Hippurus, from the Western Mediterranean Sea

AI summary Read the abstract

Researchers examined the gastrointestinal tracts of dolphinfish caught in the Western Mediterranean Sea and found microplastics present, adding to the growing body of evidence that plastic ingestion is widespread among commercially fished species in European waters.

Body Systems

Plastics are the most common marine litter typology found on the beaches and seafloor or floating on the sea surface and water column [1–3]. When these plastic items reach micro size (<5 mm) they are commonly known as microplastics (MPs) [4].

May Mesopelagic Fishes Play an Important Role as Vector of Microplastics Across the Mediterranean Trophic Web? A Case of Study in the Strait of Messina

AI summary Read the abstract

Researchers examine whether mesopelagic fish in the Strait of Messina act as vectors transferring ingested microplastics up the Mediterranean food web, finding that plastic ingestion by these deep-water species could play a significant role in contaminating higher trophic levels.

Microplastic in fish – A global synthesis

AI summary Read the abstract

A global synthesis of microplastic ingestion data from marine, freshwater, and estuarine fish found that 49% of sampled fish worldwide had ingested plastic, averaging 3.5 pieces per fish, with freshwater fish and those from aquaculture sources showing higher ingestion rates than wild marine fish. This comprehensive analysis reveals that microplastic contamination of fish — a primary human protein source globally — is now the rule rather than the exception, underscoring urgent risks to food safety.

Microplastics in the Mediterranean Biota

AI summary Read the abstract

This review synthesized evidence on microplastic ingestion, accumulation, and biological effects across Mediterranean marine biota — including fish, invertebrates, and marine mammals — assessing the ecological consequences of widespread contamination. Because Mediterranean seafood is a dietary staple for hundreds of millions of people, plastic accumulation throughout its food web represents a significant and poorly quantified source of human microplastic intake.

Preliminary Assessment of Microplastic Accumulation in Wild Mediterranean Species

AI summary Read the abstract

Wild Mediterranean marine species show measurable microplastic accumulation, reflecting the basin's disproportionately high contamination relative to global averages. These findings highlight the ecological risk microplastics pose to Mediterranean biodiversity and the seafood consumed by millions of people.
