Scientists have for the first time found microplastics in freshly fallen Antarctic snow. Microplastics stem from the erosion of plastic materials and are smaller than a grain of rice – sometimes even invisible to the naked eye. They identified 13 different types of plastics and the most common was polyethylene terephthalate (PET), mostly used in soft-drink bottles and clothing. This was found in 79% of the samples.The most likely source of these airborne microplastics is local scientific research stations. WHy should this be worrying ?
