Sandra Schoettner (marine biologist and oceans campaigner with Greenpeace Germany) doing water sampling on Joinville Island in the Antarctic Sound to investigate the presence of persistent organic pollutants like PFCs (per- and polyfluorinated chemicals) in the Antarctic environment. PFCs are widely used in industrial processes and products. The outdoor industry applies them for waterproof gear like jackets and shoes. Greenpeace has already performed this kind of sampling in other remote and seemingly pristine places in China, Russia, Turkey, Scandinavia, the Alps, and Patagonia.
