El impacto de los desechos plásticos y los microplásticos en la costa bonaerense
AI summary Read the abstract
Researchers reviewed the state of plastic waste and microplastic contamination along more than 1,200 km of Buenos Aires province coastline, covering occurrence, distribution, dynamics, and transfer to biotic components, identifying key vulnerabilities across fishing zones, tourist beaches, commercial ports, and conservation areas.
La investigación en torno a la basura plástica y los microplásticos (MPs) en zonas costeras/marinas ha generado un gran interés por parte de la comunidad científica y los organismos tomadores de decisiones, debido a los alcances globales que presenta este tipo de contaminación y al aumento casi constante la presencia en el medio ambiente. Los MPs están presentes en diferentes matrices abióticas (marinas y costeras) y accesibles para la ingestión por una gran variedad de organismos. La provincia de Buenos Aires extiende su línea costera de más de 1200 Km desde el Río de la Plata hasta la desembocadura del Río Negro, constituyéndose en un área de gran importancia para el sector productivo costero (pesca y turismo) que incluye regiones prioritarias en cuanto a su conservación, playas turísticas, cinco puertos comerciales y un puerto militar que no escapan a la problemática de los desechos plásticos y MPs. En este contexto, el presente capítulo propone revisar el estado de esta problemática para las costas de la provincia (ocurrencia, distribución, dinámica y transferencia al componente biótico) identificando sus potenciales vulnerabilidades y oportunidades que enfrenta la región.

Estudio de microplásticos en la columna de agua, sedimento intermareal y biota residente en la costa del estuario del Río de la Plata (Franja Costera Sur)
AI summary Read the abstract
Researchers studied microplastic distribution in the water column, intertidal sediment, and biota along the Rio de la Plata estuary coast in Argentina, finding contamination at all sites and in multiple organism types. The study is one of the first comprehensive assessments of microplastic pollution across multiple environmental compartments in this major South American estuary.
Transport of microplastics in the Argentine Sea: from the coastal to the Rincón and continental slope front
AI summary Read the abstract
Microplastics were sampled from both coastal and open sea areas of the Argentine Sea and found to be predominantly fibers in all locations, with concentrations decreasing from coastal to offshore stations. Fibers made up nearly all particles found at coastal sampling sites, indicating that land-based and shipping sources dominate the contamination. The study provides important baseline data for understanding microplastic distribution across a large and undersampled South Atlantic marine ecosystem.
