In a groundbreaking study, scientists have detected microplastics in freshly fallen Antarctic snow for the first time. Samples collected from 19 sites across the Ross Island region revealed an average concentration of 29 microplastic particles per liter, with polyethylene terephthalate (PET) being the most common polymer identified. This discovery underscores the pervasive nature of plastic pollution, even in Earth’s most remote regions, and raises concerns about its potential impacts on Antarctic ecosystems.
