Microplastics ingestion by Fish in the Biawak Island
AI summary
This research characterized microplastics in the atmosphere above a remote mountain observatory, collecting samples over multiple seasons to assess long-range atmospheric transport. Results demonstrated that detectable microplastic concentrations persisted even at high altitude remote sites with no local sources, with particle types and trajectories consistent with origin from coastal urban centers hundreds of kilometers distant.

AI summary Read the abstract
Researchers synthesized data from 175 assessments of plastic ingestion by fish species across Thailand's aquatic habitats, revealing widespread microplastic occurrence and raising significant concerns about ecosystem health and the potential transfer of plastic contaminants to humans through seafood consumption.
Investigation of Microplastic Abundance from Commercial Marine Fish in Bintulu, Sarawak, Malaysia
AI summary Read the abstract
Researchers investigated microplastic contamination in six commercial marine fish species from Bintulu, Sarawak, Malaysia, finding abundances between 1.48 and 3.51 particles per gram, with blue fibers under 1 mm most common and polystyrene and polyamide confirmed by FTIR analysis.
Impact of Plastic Waste Ingestion by Fish
AI summary Read the abstract
This review synthesized experimental evidence on how microplastic ingestion affects fish physiology and behavior, finding that plastics act as vectors for toxic chemicals including mercury, cause oxidative stress, and transfer contaminants up the food chain to human consumers. Because microplastics bioaccumulate through trophic levels, populations relying heavily on seafood—particularly from coastal regions—face compounded exposure risks that extend well beyond the plastic particles themselves.
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.
