Data and script contained in the article "Dark microplastics trigger changes on snow metamorphism that depend on snow initial density"
AI summary Read the abstract
This dataset and analysis script support a study examining how dark microplastics affect snow metamorphism, with effects depending on the initial density of the snowpack. The data was collected as part of research into microplastic interactions with snow physical properties in mountain environments.
This folder contains raw data and the script used to perform statistical analysis and create the figures included in the article "Dark microplastics trigger changes on snow metamorphism that depend on snow initial density”, by Isabel Marín-Beltrán, Javier Bandrés, Pablo Domínguez-Aguilar, Jorge Pey, Jesús Revuelto and Juan Ignacio López-Moreno.

Dark microplastics trigger changes on snow metamorphism that depends on the snow initial density
AI summary Read the abstract
Field experiments in the Spanish Pyrenees tested how dark microplastic particles affect snow, finding that effects depended heavily on the snow's age and density. On fresh, light snow, microplastics caused changes in snow crystal structure but minimal extra melting; on older, denser snow, heavy microplastic accumulation increased melt rates by 17% compared to uncontaminated snow. This is the first field evidence that microplastics can accelerate snowmelt, with implications for water supply timing and glacier loss in mountain regions.
On the role of Microplastics as Light Absorbing Particles in seasonal snowpacks: First evidence from the Central Pyrenees
AI summary Read the abstract
Researchers conducted six in situ lysimeter experiments in the Spanish Central Pyrenees during the 2023-2024 snow season, providing the first experimental evidence that microplastic particles act as light-absorbing impurities capable of affecting snow albedo and metamorphism in seasonal mountain snowpacks.
Supplementary data to: Nanoplastic Detection and Quantification in High-Altitude Glacial Snow Samles from Italy, Switzerland and France
AI summary Read the abstract
Researchers release the complete supplementary dataset — processed spectral data, upscaling calculations, polymer library files, and analysis code — for a nanoplastic detection and quantification study conducted on high-altitude glacial snow samples collected from Italy, Switzerland, and France.
Datasets associated with the manuscript titled "Wet and dry atmospheric deposition of microplastics at urban, suburban, rural and mountainous sites in Switzerland"
AI summary Read the abstract
Scientists tracked microplastic pollution falling from the air—both in rain/snow and as dry dust—at city, suburban, rural, and mountain sites across Switzerland over a full year. This matters because it shows that tiny plastic particles aren't just in oceans and soil—they're literally raining down on us everywhere, including remote mountain areas far from cities, meaning we're likely breathing and ingesting these particles no matter where we live. This dataset provides real measurements that researchers can use to better understand how much microplastic exposure people face just from the air around them.
