Clasificación de microplásticos en playas de Colima y Jalisco, México
AI summary Read the abstract
Researchers classified microplastics in sediment samples from 12 beaches in Colima and Jalisco, Mexico, across urban, suburban, rural, and natural beach types. The study characterized the types, colors, and quantities of microplastic particles to document contamination levels along this coastline.
Los microplásticos son una forma de contaminación marina, por ello, se debe identificar su presencia en ecosistemas como las playas, activos ambientales de valor económico que ofrecen diferentes servicios a la población. El presente trabajo identifica y clasifica los microplásticos en 12 playas de tipo urbano, sub-urbanos, rural y natural, ubicadas en los estados de Colima y Jalisco, México. Se colectaron, analizaron y clasificaron un total de 94 muestras de sedimento en la línea de pleamar, identificando mediante flotación e inspección visual un total de 12,001 microplásticos que fueron clasificados por forma, color y tamaño. Los resultados revelan que la presencia de microplásticos en playas naturales o rurales con escaso desarrollo o poco accesibles presentan niveles comparables a las urbanas y suburbanas. Esto muestra que el desplazamiento de estos contaminantes no tiene factores ambientales o antropogénicos limitantes, lo que requiere especial atención ante sus potenciales efectos en los ambientes marinos y costeros

Identificación y cuantificación de microplásticos en sedimentos de tres playas recreativas de la costa de Campeche
AI summary Read the abstract
Researchers identified and quantified microplastics in sediments from three recreational beaches in Campeche, Mexico, comparing concentrations across different seasons and sampling locations. The study found microplastics at all sites, with seasonal variation suggesting that weather patterns influence microplastic distribution on these tourist beaches.

AI summary Read the abstract
This study characterizes microplastic contamination across three sandy beaches along the central coast of Peru, documenting the types, sizes, and distribution of particles present. The findings contribute to the growing body of evidence on microplastic pollution in South American coastal ecosystems, which remain comparatively understudied relative to European and North American coastlines.
Dataset of quantification and classification of microplastics in Mexican sandy beaches
AI summary Read the abstract
This dataset presents the first national survey of microplastic contamination on 35 Mexican beaches across five coastal regions. Microplastics were found at all beaches, with fragments and pellets being the most common types, providing baseline data for monitoring plastic pollution along Mexico's coasts.
Characterization of Microplastics in Marine Sediments from the Gulf of Tehuantepec, Mexican Pacific
AI summary Read the abstract
Researchers characterized microplastics in marine sediments from the Gulf of Tehuantepec along the Mexican Pacific coast, categorizing particles by size, shape, color, and polymer type. They found widespread microplastic contamination in beach sediments near the Tehuantepec River mouth. The study provides baseline pollution data for this understudied region and raises concerns about potential impacts on benthic organisms and the broader marine food web.
