Qualitative and Quantitative Investigations of Microplastics in Pelagic and Demersal Fish Species of the North and Baltic Sea Using Pyrolysis-GCMS: A Pilot Study

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.

Advances in quantification, degradation and ecotoxicology of microplastics in marine resources

AI summary · Read the abstract

Researchers reviewed quantification methods, degradation processes, and ecotoxicological effects of microplastics in marine resources, finding that bivalves, fish, and invertebrates accumulate plastic particles that trigger oxidative stress, cytotoxicity, and inflammation while current detection methods for nanoplastics remain underdeveloped.

A multispecies bioindication framework for assessing microplastic pollution in marine fish

Current State of Research on the Prevalence of Microplastics in Aquatic Fish and Their Impact on Health

AI summary · Read the abstract

Researchers reviewed microplastic contamination in fish across all seven continents, finding marine fish were studied 2.6 times more than freshwater species, and that microplastics trigger oxidative stress, alter biochemical pathways, and accumulate through biotransformation in fish tissues globally.
