SNIP: The Greenland ice sheet is likely to be heavily contaminated with various globally emitted pollutants — such as PCBs, mercury, lead, PAHs, etc. — according to new research published in the journal Environmental Research Letters.

So, despite its image as a relatively pristine environment, Greenland is already heavily contaminated by industrial activity, which means that, as the ice sheet there thaws, surrounding waters are going to experience an influx of dangerous pollutants.

This isn’t too surprising, as much recent research has shown that the Arctic, owing to various patterns of atmospheric circulation, is now home to very high levels of industrially emitted mercury pollution. Other seemingly remote parts of the world, such as the Himalaya mountains, are also known to now be home (in the ice, snow pack, etc.) to very high levels of industrial pollutants.

Lead researcher, Dr Aviaja Hauptmann of the University of Greenland, commented: “Globally emitted contaminants accumulate in the Arctic and are stored in the frozen environments of the cryosphere, essentially meaning they have become reservoirs of toxic chemicals.”
