Microplastics Are Literally Raining from the Sky—Even in Remote Mountains

9. Bioaccumulation in Soil and Water

After falling with rain or snow, microplastics accumulate in mountain soils, rivers, and lakes, where they can persist for years.
These tiny particles are often ingested by microorganisms, insects, and aquatic life, gradually moving up the food chain.
This process of bioaccumulation raises concerns about potential toxicity and long-term ecological impacts on wildlife and ecosystems.
