A team of scientists from the University of Strathclyde in Scotland, in collaboration with researchers from Norway and the UK, has uncovered shockingly high levels of microplastic pollution in meltwater from glaciers on the Svalbard archipelago in the Arctic. Their study focused on three glaciers: Midtre Lovénbreen, Vestre Brøggerbreen, and Austre Brøggerbreen, where microplastic concentrations reached up to 1,000 particles per liter—a density comparable to pollution levels found in urban rivers like the Thames or the Yangtze. The study, published in Environmental Research, reveals that these glaciers—previously thought to be pristine—are now releasing microplastics into Arctic ecosystems as they melt.
The research team identified over 25 different types of plastic polymers, including polyethylene (used in packaging) and polyester (used in textiles), indicating that the pollution likely came from a mix of atmospheric deposition, ocean spray, and long-range transport. These findings suggest that Arctic glaciers are not just victims of climate change but also reservoirs of global pollution, now releasing contaminants into marine food chains. Scientists warn that this slow but steady release of microplastics could have long-term consequences for Arctic biodiversity and global ocean health. The study underscores the urgency for global plastic reduction policies and more intensive research into pollution stored in cryospheric systems. More
