Ingestion of Microplastics by Benthic Marine Organisms in the Ilha Grande Bay Heritage Site on Southeastern Brazil
AI summary Read the abstract
Researchers documented microplastic ingestion in ascidians and amphipods collected from Ilha Grande Bay, a UNESCO Natural Heritage site in Brazil, highlighting that even protected marine areas are affected by plastic pollution reaching benthic invertebrates.
Inappropriate disposal, management, treatment of litter are the main sources of plastic accumulation. People, animals, wind, storms, and currents spread continuously the plastic in different sites in the world. Diverse animal groups have been ingesting small particles of plastic, the microplastics (MPs), resulting in negative effects in behaviour, consumption, and nutritional rates. Here, we reported the ingestion of MP by two benthic groups, Ascidiacea and Amphipoda from sites around llha Grande Bay, a Natural Heritage of Humanity site in the Southwest of Brazil.

Microplastics in a mosaic of Marine Protected Areas from southeastern Brazil: An assessment based on filter-feeding bivalves
AI summary Read the abstract
Researchers used filter-feeding bivalves as biological monitors to assess microplastic contamination across 28 marine protected areas along a heavily populated stretch of coastline in southeastern Brazil. They found microplastics in bivalves from all sites surveyed, demonstrating that protected status alone does not shield marine areas from plastic pollution. The study highlights how diffuse, transboundary plastic contamination reaches even designated conservation zones.

Contaminação e toxicidade de microplásticos em uma área de proteção marinha costeira
AI summary Read the abstract
This Brazilian study assessed microplastic contamination and toxicity in a coastal marine protected area, finding that sandy beaches accumulate plastic particles carried in by the ocean. The research highlights that even protected coastal zones are not immune to microplastic pollution, which can be ingested by marine wildlife and enter food webs.
