"Scientists in Germany are raising the alarm after finding a significant amount of microplastics in snow samples in the Alps and the Arctic — two of the most pristine locations on Earth. In a study published in the journal Science Advances last week, the researchers said their findings point to a troubling possibility: that plastics aren’t just polluting our lands and clogging our waterways, but befouling the air around us as well. “I was really astonished concerning the high concentrations” of microplastics found in Arctic snow, study co-author Gunnar Gerdts told the Los Angeles Times. Microplastics are tiny fragments of plastic that often originate from larger debris that have degraded over time. Gerdts’ team said it found up to 14,400 microplastic particles per liter of melted Arctic snow ― a staggering amount for a remote region where few humans reside. “We found a lot of microplastics, like record concentrations,” Gerdts said of the Arctic snow, “and the question arose: From where does the microplastic originate?” There are just two possibilities, he noted: “from the water or from the air.” While it’s known that microplastics and other plastic debris is transported by ocean currents, scientists have become increasingly convinced that small plastic fragments are also being carried through winds and precipitation."
