Contaminación por microplásticos en el acuífero kárstico de la península de Yucatán
AI summary Read the abstract
Researchers sampled water from cenotes and wells throughout the Yucatan karst aquifer and identified microplastic particles in every groundwater sample, with fibers comprising 94% of particles and concentrations ranging from 10 to 936 particles per liter, establishing that this primary regional drinking water source is universally contaminated with microplastics.
La contaminación por microplásticos (MP) afecta a los ecosistemas terrestres, acuáticos y aéreos. Existen pocos estudios que han analizado la presencia de MP en aguas subterráneas. El acuífero kársticode la península de Yucatán (AKPY) es la principal fuente de abastecimientode agua de la región. Por lo cual, el objetivo del estudio fue determinarla presencia de MP en AKPY. Se tomaron muestras de agua de cenotes y pozos, se filtraron y el material retenido en el filtro se observó en un microscopio estereoscópico para identificar y clasificar los MP. Las formas de MP observadas fueron las fibras (94%) y el color más abundante fue blanco (51%). La concentración máxima fue de 936 partículas L−1 y la mínima de 10 partículas L−1. Se encontró presencia de MP en todas las muestras de agua subterránea, por lo que es imprescindible determinar lasfuentes para mitigar su presencia en AKPY

First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
AI summary Read the abstract
Researchers conducted the first investigation of microplastic pollution in groundwater in Latin America, analyzing six capped boreholes in a coastal aquifer in northwest Mexico for microplastic abundance, concentration, and characteristics. The study detected microplastics in groundwater samples, establishing baseline contamination data for this understudied environmental compartment and raising concerns about drinking water quality in the region.
First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
AI summary Read the abstract
This is the first study to investigate microplastic contamination in groundwater in Latin America, examining a coastal aquifer in Northwest Mexico. Researchers found microplastics at all six sampled locations and at multiple depths, confirming that groundwater is not immune to this type of pollution. Since millions of people depend on groundwater for drinking water, these findings raise important questions about microplastic exposure through water supplies.

Researchers detected microplastics in drinking water from ten rural wells in two Mexican communities, finding diverse polymer types and morphologies at concentrations that suggest widespread groundwater MP contamination even in areas distant from major urban pollution sources.
Microplastics in Groundwater of Two Rural Communities in Mexico
AI summary Read the abstract
Researchers sampled ten rural drinking-water wells in Mexico over ten months and detected microplastics at concentrations up to 0.41 MP/L, with all particles appearing as fragments composed of nylon, HDPE, PP, PS, PVC, and PET, and found that microplastic abundance was higher in the dry season, suggesting rainfall dilutes groundwater contamination.
