Presencia de microplásticos en especies marinas del Parque Nacional Marino las Baulas
AI summary Read the abstract
Researchers detected microplastics in the digestive systems of seven pelagic fish species and one benthic crustacean from Marino Las Baulas National Park on Costa Rica's Pacific coast, finding microplastics in 89% of fish (averaging 3.75 particles/fish, predominantly fibers) and 76% of crustaceans. This first report from this protected area confirms plastic contamination has reached high-trophic-level marine species in the region.
La ingesta de microplásticos (MPs) en diversas especies marinas ha sido reportada en la literatura, sin embargo, el grado de contaminación en los sistemas y la biota asociada a estos es poco conocido. En este estudio se presentan los resultados de la presencia de microplásticos en siete especies de peces pelágicos y de una especie de crustáceo bentónico, todos de alto nivel trófico del Parque Nacional Marino Las Baulas. Mediante digestión química e inspección visual se extrajeron microplásticos del sistema digestivo de 56 individuos. Un total de 90 piezas fueron extraídas del 89% de los peces (93% fibras) con 3,75±1,70 (SD) microplástico/pez. Se determinó una cantidad significativamente menor en los crustáceos con un total de 58 piezas extraídas del 76% de los individuos analizados con 2,64±1,36 (CF) microplástico/jaiba. Se realiza una búsqueda de microplásticos en tejidos musculares mediante la técnica de histología y se encontraron lesiones en el tejido muscular de los peces, pero los resultados no fueron atribuibles a MP, por ende, no se ahondará en estos datos. Este artículo reporta la presencia de estos contaminantes en especies marinas de alto nivel trófico en la costa del Pacífico de Costa Rica, lo cual confirma la afectación por plásticos en la zona de estudio, reforzándose la necesidad de una gestión adecuada de los residuos sólidos generados por la población, tanto en la zona terrestre como en la zona marítima.

Microplastic in high tropical level marine species
AI summary Read the abstract
Researchers examined microplastic ingestion in seven pelagic fish species and one benthic crustacean from a Costa Rican national marine park, all of high trophic level. Microplastics were found across species, with variations in abundance and type linked to feeding strategy and habitat. The findings raise food safety concerns and suggest that top-trophic marine species in protected areas are not shielded from plastic contamination.

Researchers conducted a comprehensive assessment of microplastic contamination across global Marine Protected Areas, finding that these conservation zones are not immune to plastic pollution and highlighting the need for targeted mitigation strategies.
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.
Microplastics found in the World Heritage Site Cocos Island National Park, Costa Rica
AI summary Read the abstract
Microplastics were found in both marine and freshwater environments of Cocos Island, Costa Rica, a UNESCO World Heritage Site. Samples from ocean surface water, freshwater streams, and sediments all contained plastic particles, despite the island's remote location. The findings demonstrate that protected marine areas are not immune to microplastic contamination.
