Presença de microplásticos no conteúdo estomacal de Micropogonias furnieri da região estuarina de Santos
AI summary Read the abstract
Researchers examined stomach contents of 30 whitemouth croaker (Micropogonias furnieri) from the Santos estuary in Brazil and found microplastics in 20% of specimens, raising concern about exposure to emerging pollutants — particularly fishing-related materials — in this economically important estuarine species.
Microplásticos (MP) são partículas medindo entre 0,1µm e 5mm, e quando presentes no oceano são capazes de afetar a biota marinha a partir de sua ingestão e/ou toxicidade. Em vista a importância da Corvina, Micropogonias furnieri, à região estuarina de Santos, esse estudo teve o objetivo de analisar o conteúdo estomacal de 30 exemplares da espécie dessa região, relatando a presença ou não de microplástico. Resultou-se que dos 30 exemplares analisados, 20% apresentaram microplásticos. A ingestão desses MP por corvinas reflete em grande desregulação fisiológica a esses animais e alertam à exposição de poluentes emergentes na região de estudo, principalmente a materiais utilizados na pesca.

AI summary Read the abstract
Researchers quantified microplastics in seafloor sediments and digestive tracts of whitemouth croaker (Micropogonias furnieri) across Guanabara Bay, Brazil, finding uniformly high concentrations of transparent polyester fibers in both sediments and fish, with smaller fish ingesting proportionally more plastic, suggesting direct sediment ingestion as a primary exposure pathway.

Researchers analyzed stomach contents from 40 Guiana dolphins (Sotalia guianensis) collected over 10 years off the Ceará coast of Brazil, finding that 95% were contaminated with plastic, with microplastics (averaging 7.77 particles per individual) far more prevalent than larger plastic items and polyurethane, PET, and EVA as the most common polymers.

Researchers evaluated the ingestion of microplastics by 28 Sciaenidae and 12 Ariidae fish species from estuaries in Tumaco and Buenaventura Bay, Colombia, examining stomach contents of 1,652 specimens across high and low precipitation seasons in 2020-2021 and analyzing how trophic level and other biological characteristics influence microplastic uptake.
Differential microplastic contamination of waterbirds in a coastal region associated with trophic groups and spatial distribution
AI summary Read the abstract
A study of waterbird feces in southern Brazil found that shorebirds feeding in sediments had far higher microplastic loads than fish-eating birds, and contamination was worst near urban areas, with polyester and PVC the most common polymers detected. Trophic position and proximity to cities both shape how much plastic wildlife ingests, providing a natural monitoring system for tracking coastal microplastic pollution.
