Researchers have found microplastics in 20 of 21 snow samples taken from the Arctic . A study published in Science Advances analysed the microplastic ##s in the Arctic , comparing them to snow in the Swiss Alps and samples from Fram Strait ice floes . The concentrations found in Arctic snow , while still significant , were much lower than in Europe . The sizes of detected microplastic particles were in the smallest measurable size range , indicating there may be large amounts of particles below the detection limit . Exclusion of this value decreases the mean to 0.18 ± 0.07 × 103 N liter−1. The particles ' transport to the Arctic is unclear , but atmospheric transport and deposition are likely methods .
