Relatos de Microplásticos em Três Espécies de Peixes Comerciais no Vale do Juruá
AI summary Read the abstract
Researchers documented microplastic occurrence in the digestive systems of three commercially important fish species — Mylossoma duriventre, Prochilodus nigricans, and Triportheus angalatus — from the Juruá Valley in the Brazilian Amazon, reporting 21 total fragments and the first recorded microplastic detection in Triportheus angalatus.
A presença de microplásticos tem sido relatada em diversos estudos, em diferentes localizações geográficas e ambientes, devido ao consumo humano, como alimentos e bebidas, gerando crescentes preocupações na comunidade científica. Assim, o presente trabalho objetivou relatar a ocorrência de fragmentos plásticos no sistema digestório em três espécies de peixes de valor comercial no município de Cruzeiro do Sul, Acre, Brasil. Foram analisadas 30 amostras das espécies Mylossoma duriventre, Prochilodus nigricans e Triportheus angalatus, sendo 10 indivíduos de cada espécie. As análises indicaram a presença de microplásticos nas três espécies, com um total de 21 fragmentos observados, sendo a maioria encontrada nas espécies Mylossoma duriventre e Prochilodus nigricans, e a primeira ocorrência de microplásticos na espécie Triportheus angalatus. Os resultados obtidos visam contribuir para um melhor entendimento dos riscos associados aos microplásticos, por se tratar de espécies comerciais na Região do Vale do Juruá.

Presença de resíduos plásticos no trato digestório de tainhas (Mugil liza) do estuário de Cananeia, sudeste do Brasil
AI summary Read the abstract
Researchers analyzed the digestive tracts of mullet (Mugil liza) from a Brazilian estuary for the presence of plastic residues, finding ingested plastic fragments in a substantial proportion of examined fish. The study links plastic ingestion rates to proximity of fishing sites to urban waste inputs and adds to evidence of widespread plastic ingestion in commercially important fish species.
