Impacts of Microplastics on Piscivorous Aquatic Birds in the Amazon
Original title: Impactos De Microplásticos Em Aves Aquáticas Piscívoras Na Amazônia
AI summary Read the abstract
Researchers assessed microplastic impacts on piscivorous aquatic birds in the Amazon basin, examining how plastic particles move through freshwater food webs to accumulate in top avian predators in one of the world's most biodiverse river ecosystems.

AI summary Read the abstract
Researchers assessed microplastic contamination in commercial fish species from the Amazon basin, examining ingestion rates and tissue distribution in ecologically and economically important freshwater fish.
Evaluation of Microplastic Pollution in Gills of Freshwater Fish in a Neotropical Hydrographic Basin, Brazil
AI summary Read the abstract
Analysis of gill tissue from 98 freshwater fish across eight species in Brazil's Sorocaba River basin found microplastics in every individual, with fibers comprising 74% of the 385 particles detected and highest contamination in the most disturbed river. The universal gill contamination across species demonstrates that freshwater fish in human-impacted watersheds serve as a direct route for microplastic entry into aquatic food webs and ultimately human diets.
Does deforestation contribute to microplastic contamination in stream fish in the Southwestern Amazon?
AI summary Read the abstract
A study of 584 fish from 20 Amazon streams found that fish in deforested areas ingested significantly more microplastics than those in forested watersheds, with feeding strategy and seasonal flooding also influencing exposure. Deforestation not only threatens biodiversity directly but also increases wildlife exposure to plastic pollution, compounding the ecological damage of forest loss.
Biochemical responses and ingestion of microplastics by native fishes in the Atlantic Forest, southern Brazil
AI summary
Researchers assessed fish health along a contamination gradient in Brazil's Atlantic Forest and found that microplastic accumulation was highest in carnivorous fish at impacted midstream sites, while biochemical stress markers were elevated even in upstream areas considered relatively pristine, underscoring the need for ongoing biomonitoring.
