Microplastics Contaminate Snow from Alps to Arctic

By Jacqueline Mattos (@mattosjacq) Microplastics are tiny pieces of plastic that pollute the environment and can range from 0.05 to 5 millimeters in length. Bigger plastic items can be fragmented by the action of light, temperature fluctuations, ocean waves, or mechanical abrasion into smaller pieces that are widely dispersed, persistent in the environment, and sometimes accompanied by microorganisms. A recent article by Bergmann et al., published in the periodical Science Advances, assessed quantities of microplastics in the snow from the Alps and other northern European sites to the Arctic and…

The sheer scale of marine plastic pollution is staggering: over 5.25 trillion pieces of plastic are estimated to engulf the oceans. And the amount of plastic entering the oceans is expected to increase by an order of magnitude by 2025. In the “Great Pacific Garbage Patch” located between California and Hawaii, almost half of the waste by size comes from fishing nets. Marine plastic waste is not just…
